The nasopharyngeal swab test does not produce painful symptoms, and some patients experience discomfort. This inspection is to use a medical flocked swab to enter the nasopharynx to take a small number of secretions and send them for inspection. The pathogenic bacteria can be isolated through bacterial culture. During the operation, the patient will experience mild nausea and discomfort, which is generally within the tolerable range. During the operation, the medical staff is gentle and skilled, so there will be no pain.

Activates unconscious, instinctive reflexes. Depending on the intensity of the body’s response, discomfort, tearing, pain, and other reactions can result. Some people gag, cough, sneeze – it’s all part of the same reflex. For people who are more prone to headaches, this can cause intense discomfort.

Swab testing generally takes nasal swabs and throat swabs, and the sampling methods of these two are also different.

A nasal swab refers to a swab deep from the nasal cavity, all the way to the nasopharynx, and the secretion is taken for smearing.

Throat swabs are taken directly from the posterior pharyngeal wall of the oral cavity and the tonsillar fossa by opening the mouth. Nasal swabs are generally slightly more painful than throat swabs because they need to be passed through the nasal cavity. If there are structural abnormalities in the nasal cavity, such as a deviated nasal septum or hypertrophy of the turbinate, or there is hyperplasia in the nasal cavity, such as nasal polyps or the operator does not know much about the anatomical structure of the nose, it is possible that a cotton swab may not easily reach the nasopharynx through the nasal cavity. Partial or damaged nasal mucosa, causing local bleeding or pain and other discomforts.

Nasal swab and throat swab which is painful?

Which is more accurate between nasal swab and throat swab? Essentially, if the operation is standardized, there is basically no difference between the two sampling methods, but we usually eat and drink water, etc., which will reduce the virus accumulation in the oropharynx to a certain extent. , In practice, the positive detection rate of nasal swabs is slightly higher than that of throat swabs. In general, oropharyngeal swabs are suitable for most people and are convenient and fast, while nasopharyngeal swabs are slightly more accurate, but the human body does not feel comfortable.

Precautions before nasal swab testing?

1. Try to avoid eating 2 hours before the nucleic acid test to avoid vomiting;

2. During the inspection, reduce swallowing and do not do throat clearing (such as expectoration and spitting).

3. Pay attention to maintaining a distance of more than 1 meter between people and minimize conversations;

4. Do not drink beverages (including water), smoke, drink, chew gum, etc. 30 minutes before sampling;

5. The tested person should be informed Whether the collection personnel have a relevant past medical history (such as the history of nasal surgery, deviated nasal septum, blood disease, throat disease, etc.);

The person who did a few nasal swabs tells you how to do it without pain.

I’ve done nasal swabs several times and it’s been painless every time. Much more comfortable than a throat swab. I see a lot of netizens saying that the nasal swab is very painful and sour, this is because your posture is not correct! !!

Looking at this schematic diagram, in fact, no matter the nasal swab or the throat swab, their purpose is to let the cotton swab sample from the inner wall of the throat. Nasal swabs are not meant to poke your heavenly lid!

Therefore, you should tilt your head as far back as possible to allow the flocked swab to go in horizontally. That way the only thing you feel is a little bit of cold, and it’s over in less than 5 seconds. But if you keep your head upright, the cotton swab can only be stabbed from the bottom to the top, which will definitely stab the upper part of the nasal cavity. That position is very sensitive, and it hurts when stabbed. And because the doctor can’t see the location, he can only stir in it by the feel of the hand, so you will be sour to tears.

The Mission of A Virus Test Swab

From the sampling point to the testing room, then to the temporary storage point of medical waste.

Then to the hazardous waste centre, to the power plant, and finally to the soil.

A swab for nucleic acid detection completed the task and became a piece of pollution-free ash and fill it in the soil.

At present, we are in a critical period of anti-epidemic.

An ordinary hospital has a maximum of 11,220 samples per day at a single sampling point.

The Mission of A Virus Test Swab

The Mission of A Virus Test Swab

At nine o’clock in the morning, at the nucleic acid testing and sampling service point, citizens who were ready to test lined up.

Everyone wears a mask and consciously separates one meter from each other.

At the beginning of the inspection window, the heavily armed nurses washed their hands with an antiseptic solution.

And then removed a flocked swab about 15 cm long from the packaging bag to take a sample before taking the throat swab.

The nurse opened the collector’s mouth wide, and she skillfully inserted the flocked swab into her pharynx.

Then picked up a sampling tube (virus transport medium) with her left hand. And inserted the collection stick into the sampling tube with her right.

With a little force, the tip of the cotton swab breaks enters the sampling tube, seals it. And throws the long stick into the yellow medical waste bin.

As a testing point for ordinary citizens and inpatients, as an ordinary citizen and inpatients, the use of cotton swabs in an ordinary hospital reached 11,220.

Medical waste treatment forms closed-loop management in nucleic acid testing laboratories.

Take the flocked swab, put the swab head into the sampling tube, and paste a barcode similar to “ID card”. And carefully seal it, put it into a transparent sealed box.

And then send it to the transfer cabin of the PCR laboratory of the Department of Infectious Diseases by staff wearing protective clothing.

The PCR laboratory is under negative pressure, and after the virus enters, it cannot come out. After the outbreak, the PCR laboratory strictly abides by the medical waste treatment process, forming closed-loop management of the laboratory.

An hour later, staff in protective suits transported medical waste out of the ward in sealed yellow bags and sealed with “extremely infectious waste”.

Then, the workers send these medical wastes by trolleys to the medical waste temporary storage area at the nucleic acid collection point 100 meters away. For the medical wastes for nucleic acid testing, he transports an average of about 35 kilograms per day.

We need to place the virus sampling tube for 48 hours during the transfer process

Except for professionals, our PCR laboratory does not allow patients and the public to enter here.

To ensure safety, all medical waste from nucleic acid testing collection points, including swab sticks, is kept here for 48 hours.

After our test results come out and are confirmed to be correct, they will be sent to the hazardous waste treatment centre by a medical waste transfer vehicle.

At ten o’clock in the morning, the staff of the hazardous waste centre arrived at the scene. Unload the empty shipping box and load the ship with medical waste that has been sitting for 48 hours.

The sampling flocked swabs used must be incinerated at high temperatures above 1100°C.

There are two buildings, an incineration workshop and a cooking room, in the yard of the Hazardous Waste Center.

The staff in protective suits skillfully unload boxes of medical waste from the transfer vehicle and load boxes of hazardous waste into bucket elevators.

How to Swab For Covid Test

Since the outbreak of novel coronavirus pneumonia, we must have experienced nucleic acid testing. Covid swab test Nucleic acid detection plays a very important role in the process of infection diagnosis of COVID-19. It can not only find asymptomatic patients in the incubation period as much as possible but also greatly reduce the risk of infection.

Nucleic acid detection is so important. Next, Dr Li will take you to have an in-depth understanding of the relevant principles of nucleic acid detection, the difference between mixed collection and single collection of nucleic acid detection, and the matters needing attention in nucleic acid detection, to help you better protect yourself while popularizing knowledge.

To understand nucleic acid detection, we must understand the detection principle. Let’s take a look at its detection principle first.

The doctor is testing the patient's nasopharynx swab

The doctor is testing the patient’s nasopharynx swab

What is the principle of nucleic acid detection?

Nucleic acid, the genetic factor of the virus, is a macromolecular chain composed of four nucleotides. Different molecules represent different nucleotides and form a long chain. Nucleic acid detection is through the detection of nucleic acid in the chain, and this segment of nucleic acid is COVID-19 specific, other viruses do not.

Pcr test nasal swab and an antigen test difference for covid 19

The substance detected by the nucleic acid is the nucleic acid of the virus. At present, the detection technology is mainly through PCR (polymerase chain reaction) technology to detect the nucleic acid of the virus. During the detection, the nucleic acid chain of COVID-19 was used as the detection target, and the target gene sequence was amplified by PCR Test, which was combined with a fluorescent labelled probe added in the test reagent to produce a fluorescence signal.

The three forms of nucleic acid detection have their advantages.

Nasal swab test

This test method is to insert the test swab vertically into the nostril. And gently rotate the swab, stay in the nasal cavity for about 15 seconds, to test.

Compared with throat swabs, nasal swab testing is more accurate for inexperienced testing personnel. And the risk of exposure is lower. However, it is not suitable for some patients with nasal allergies, high blood pressure and people who take anticoagulation and antiplatelet for a long time.

Throat swab test

At present, the most widely used detection method is also a form that is often used by everyone. During the sampling process, the patient opened his mouth and made an “ah” sound, and the testing personnel used a sterilized cotton swab to gently and quickly wipe the pharyngeal lateral wall and posterior pharyngeal wall of the subject many times.

COVID-19 Testing: Throat swab test

Throat swab testing: Often used in the testing process because it is more convenient and fast to collect, and it is more acceptable to the public, but the risk of exposure is also greater.

Anal swab test

This test method is a method of inserting a test swab into the anus and taking a sample at the fold of the anus or taking a sample at 2 to 3 cm for a new coronavirus test.

Many patients reject anal swab testing, but anal swabs can improve the accuracy of testing for new coronavirus infections to a certain extent. Some patients indeed have negative throat swabs, but positive ones are detected by anal swabs. In some patients, the anal swab test was still positive after the other two tests turned negative.

Why do multiple nucleic acid tests need to be performed?

Multiple nucleic acid tests are necessary for epidemic prevention and control.
A negative nucleic acid test does not mean that the tested person is not at risk of infection. Any detection method has the possibility of errors, especially in high-risk areas. To ensure the accuracy of the inspection results and better prevent and control the spread of the epidemic, multiple rounds of inspections must be carried out. There are also the following reasons for taking multiple rounds of detection:

After virus infection, the human body has a certain value-added period. When testing, if the virus in the body does not reach a certain concentration, we may not detect the virus.

When the specimen was collected, due to the different sampling methods, no virus cells were collected. False-negative specimens can also lead to inaccurate collection results.

Errors in the transportation process and storage of samples for inspection will also affect the results of nucleic acid testing.

Therefore, for risk areas and special populations, multiple rounds of nucleic acid testing must be carried out to more accurately and effectively detect the virus source, so as to better and more accurately prevent and control and identify infected people, and cut off the source of the virus. No matter what kind of inspection process, attention must be paid.

During the outbreak of the new coronavirus pneumonia, while everyone is doing personal protection, they are also very concerned about the epidemic situation.

Originally, the social season in winter and spring was a period of the high incidence of common colds and flu, and the most important means to control the epidemic was to screen out the real patients with new coronary pneumonia from many respiratory patients.

The following small series will introduce some common virus sampling detection methods for you.

Nasopharyngeal swab

Collect nasopharyngeal swab specimens within 3 days of the onset of the patient as much as possible.

Measure the distance from the tip of the nose to the earlobe with a swab and mark it with your finger, insert the swab into the nasal cavity in the direction perpendicular to the nose (face), and the swab should be at least half the length from the earlobe to the tip of the nose so that the swab stays in the nose for 15 ~30 s.

Gently rotate 3 to 5 times, quickly put the swab into a sample collection tube containing 2 ml of lysis buffer (the same as the lysis buffer in the nucleic acid extraction kit) or a cell preservation solution containing RNase inhibitors, and insert the swab.

Then break the sterile swab rod near the top, screw the cap tightly and seal it with parafilm.

Oropharyngeal swab

Collect throat swab specimens from patients within 3 days of onset as much as possible. It is advisable to use a sterile flocked swab for sampling, wiping the posterior pharyngeal wall with moderate force, avoiding touching the tongue; quickly put the sterile swab into the collection tube used for collecting nasopharyngeal swabs, and break it near the top Sterile swab rod, screw cap tightly and seal with parafilm.

Anal swab (feces)

For patients with gastrointestinal symptoms such as diarrhea in the early stage of the disease, an anal swab should collect a stool sample (soybean size) of 3-5g.

The specimens were collected in a screw-cap specimen collection tube containing 2 ml of normal saline (RNase inhibitor can be added if available) and sealed with parafilm.

How to collect nasopharyngeal swabs

There is absolutely no need for the sampler to stand directly opposite the patient. Regardless of whether the patient is sitting or lying, right-handed patients can stand on the right side of the patient, and left-handed patients can stand on the left side for sampling operations.

The advantage of standing on the side is that if the patient has a cough, sneeze, etc., it can be avoided in time.

After the nasopharyngeal swab is passed through the nostrils.

It is perpendicular to the coronal plane of the head or the face and penetrates deep from the inferior meatus to the posterior wall of the nasopharynx, and it is enough to feel the wall.

The nasopharyngeal swab enters the nasal cavity to a depth of approximately the distance from the tip of the nose to the earlobe (see figure).

The “American Society for Microbiology Clinical Microbiological Specimen Submission Guidelines. ” We ask to twist the nasopharyngeal swab on the nasopharyngeal mucosa, hold it for 10-15 seconds, and then take out. Children’s cooperation is poor.

We generally take out the Flocked swab in three to five seconds after fully twisting it 2-3 times.

Except for paying attention to the depth of the swab. We should also note that there is always the habit of having the patient lift their head completely, bend the swab, and take a sample. This is wrong.

In fact, the above approach is wrong. This operation will cause the swab head to stay in an incorrect position. And the final sample obtained is not a standard nasopharyngeal swab specimen.

COVID-19 Swab Test : Positive Covid Test

Posted on by

Despite the recent surge in coronavirus cases, most Premier League clubs hope to continue playing during the holiday season. Due to the Covid-19 outbreak, only half of the game last weekend was left, and each round of new swab tests will continue to yield results of increasing cases.
This led several top coaches to question the safety of continuing.
Currently, all fans can still enter the stadium. However, there are reports that the UK may adopt secondary measures after Christmas. According to these regulations, only 2,000 spectators are allowed to watch the game.

Here is how to test for COVID-19 and what to do if the test result is positive.
 Stock up on healthy foods and anti-fever medicines, and avoid contact with others. Try to watch football matches at home.

COVID-19 testing methods.

COVID-19 infections have surged again, so you may find that you test positive.
With the highly contagious variant of Omicron circulating in many countries, reinfection is common, and people who are vaccinated may be susceptible to mild infections.
It is important to take precautions and be prepared to act if you are infected.

Here is how to do it:

How to confirm if you have COVID-19

As we all know, the symptoms of Covid-19 include “fever, fatigue, and dry cough”. Some patients will have symptoms such as nasal congestion and runny nose. Viruses are also a very large family. In the face of a turbulent epidemic, how doctors can quickly distinguish whether it is a “2019-nCoV” virus infection in the first place is obviously the key to fighting the epidemic.

What are the symptoms of COVID-19?

Some people infected with the virus have no symptoms. When the virus does cause symptoms, common symptoms include fever, body aches, dry cough, fatigue, chills, headache, sore throat, loss of appetite and loss of smell. In some people, COVID-19 can cause more serious symptoms, such as high fever, severe cough, and shortness of breath, which usually indicates pneumonia.
People with COVID-19 can also experience neurological symptoms, gastrointestinal (GI) symptoms, or both. These may or may not have respiratory symptoms.
For example, COVID-19 affects the brain function of some people. Specific neurological symptoms seen in people with COVID-19 include loss of smell, tastelessness, muscle weakness, tingling or numbness in the hands and feet, dizziness, confusion, delirium, seizures, and stroke.
In addition, some people have gastrointestinal (GI) symptoms such as loss of appetite, nausea, vomiting, diarrhea, abdominal pain, or discomfort related to COVID-19.
If you have been (or you suspect you may have been) exposed to COVID-19, You should also test whether you are experiencing symptoms.

How to test for COVID-19?

Special diagnostic tests must be performed to confirm that someone has an active coronavirus infection.

In most cases, the clinician will take a nasopharyngeal swab (or nose and throat swab).

Certain tests can be performed with saliva samples. Then check the genetic material of the virus in the sample (PCR test) or specific viral protein (antigen test).

Antibody testing can tell if someone has COVID-19. But an infected person does not immediately start to produce antibodies. It can take up to three weeks for a blood antibody test to become positive. This is why it is not useful as a diagnostic test for people with new symptoms.

How reliable is the test against COVID-19?

COVID-19 Swab Test: flocked swab test kits

COVID-19 Swab Test: flocked swab test kits

Currently, there are two types of diagnostic tests in the United States. The PCR test can detect viral RNA. Antigen tests (also called rapid diagnostic tests) detect specific proteins on the surface of the coronavirus. Antigen test results may recover within 15 to 45 minutes; you may need to wait a few days or longer to get PCR test results.

The accuracy of any diagnostic test depends on many factors, including whether the sample is collected correctly. For PCR tests that are usually analyzed in the laboratory, the test results may be affected by the conditions under which the test is shipped to the laboratory.

The test time will also affect the results. For example, if the test is performed on the day of infection, it is almost certain that the test result will be negative because there are not enough virus particles to detect in the nose or saliva. If the test is performed a few days after infection or a few days after the onset of symptoms, the chance of getting a false negative test result will decrease.

Generally speaking, if the test result is positive, it is almost certain that the person has been infected.

The negative test result is uncertain. The false negative rate of antigen testing is higher. If your antigen test result is negative, your doctor may order a PCR test to confirm the result.

Self-quarantine for 10 days

If you test positive for the virus, you should self-quarantine for 10 days.

CDC says this means don’t leave your home unless there is an emergency.
How soon after contracting the new coronavirus will I start the infection?
Emerging research shows that people are actually most likely to spread the virus to others within 48 hours of the onset of symptoms.

If you live with your family or roommates, keeping your distance is a challenge.
The ultimate goal is that you do not share the air with anyone else.

This means sleeping in a separate room with a separate bathroom, rather than in the same space, such as a kitchen or living room.

Ideally, have friends or family members leave food and drinks outside the door for you to collect.

What does self-quarantine or quarantine mean? What should I or shouldn’t I do?

It is important not to spread the infection to other people during the recovery process.

Although home isolation or home isolation sounds like a stay, you should be prepared for a long time during which you may feel disconnected from others and feel anxious about your own health and the health of your loved ones.

Staying in touch with others over the phone or online can help maintain social relationships, ask for help, and update others based on your situation.

Separate yourself from other people and animals in the house.

Stay in a specific room as much as possible and stay away from other people in your home. Use a separate bathroom (if available).
Wear a mask when you are sick.

Wear a mask when you are with others or pets, and before entering a doctor’s office or hospital.

Cover up coughing and sneezing.

When coughing or sneezing, cover your mouth and nose with a tissue, and then throw the used tissue into the lined trash can.

After sneezing, immediately wash your hands with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer with an alcohol content of at least 60% for cleaning.

Clean your hands often.

Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing or sneezing; going to the bathroom; before eating or preparing food.

If soap and water are not readily available, use an alcohol-based hand sanitizer with an alcohol content of at least 60% to cover all surfaces of your hands and rub them together until it feels dry.

Avoid touching your eyes, nose and mouth with unwashed hands.

Don’t share personal household items

Do not share dishes, drinking glasses, cups, eating utensils, towels or bedding with others or pets at home.

Monitor symptoms

Check your temperature twice a day to monitor if you have a fever and stay alert for coughing or breathing difficulties.

If you are asymptomatic and start to have a fever or fever, cough or difficulty breathing, immediately limit contact with others (if you have not already done so).

Call your doctor or local health department to determine if you need a medical evaluation.

Cell medical Confirm COVID-19 Diagnostics Cover Omicron Variant

Cell medical Corporation has announced that its established CE-IVD marked Iclean® SARS-CoV-2 flocked swab real-time multiplexed PCR assay reliably detects all SARS-CoV-2 variants.

And in addition, is expected to also provide a clear indication of Omicron (B.1.1.529), recently declared a ‘variant of concern’ by the WHO.

Iclean® SARS-CoV-2 flocked swab is a multiplexed CE-IVD marked PCR assay for the detection and quantification of all major SARS-CoV-2 variants, based on Cell medical´s proprietary technology.

In addition, the assay simultaneously detects the S-gene mutations Del69-70 and N501Y, which are expected to be clear indications that the variant is Omicron (B.1.1.529).

The new Omicron variant shares these mutations with the Alpha variant (B.1.1.7), but the Alpha variant is meanwhile of low epidemiological interest and only gets detected sporadically.

Accordingly, by identifying Del69-70 and N501Y, the laboratory has an indication that the sample most probably is the SARS-CoV-2 Omicron variant.

This can subsequently be confirmed by genomic sequencing, as is standard practice.

The Iclean® SARS-CoV-2 flocked swab also provides a viral load result according to WHO standard (IU/ml), as well as CP values and easy interpretation of mutations.

The test is validated for use with nasopharyngeal and oropharyngeal swabs and contains reagents for 96 reactions.

Sample extraction, amplification, and PCR results are available in under 3-4 hours.

Using the Iclean® SARS-CoV-2 flocked swab assay allows the user to run a screening tool for detecting SARS-CoV-2, viral load, and an early indication of the Omicron variant.

Moreover, Cell medical is pleased to confirm that their full range of other Iclean® SARS-CoV-2 assays is also expected to reliably detect the Omicron variant (B.1.1.529). These assays include:

* Not for Sale in the USA
** Not for use in clinical diagnostics procedures

All our SARS-CoV-2 assays are CE-IVD-labeled according to the European IVD Directive 98/79/EC.

And mainly sold into European Markets.

Iclean® SARS-CoV-2 plus is also registered and sold in some African markets including South Africa.

    As we learn more about COVID-19,

    Protect yourself and others: COVID-19, do a new crown swap test and get a new crown vaccine.

    On this page, you will learn:
    What should we pay attention to during holiday gatherings?

    Of course, Cell Medical recommends minimizing unnecessary gatherings. For you and your family and friends.

    The latest mutation of the new crown epidemic has increased the risk of transmission.

    Faced with the epidemic, but the company arranges to travel, what should I do?

    Please do a nasopharyngeal swab test before going home.

    About nylon flocked nasal swab

    What should we pay attention to during holiday party activities?

    Cell medical company offers a variety of ways to enjoy the holiday tradition and protect your health.

    We encourage colleagues in the United States to take the following steps to make your holiday gatherings safer.

    To do a nasopharyngeal swab test, maybe we have to confirm whether we have been to a high-risk area before the party. Whether to carry the new crown virus, a flocking nasopharyngeal swab test is the best choice.

    Take a COVID-19 swab test so you can find out before you go. You can go to the test site or use the home test program. Of course, we recommend that you go to a professional testing agency for nasopharyngeal swab testing.

    Some locations may be closed on or around holidays. Check it a few hours before departure.

    vaccination. The best way to ensure the safety of your family and friends is to get vaccinated if you and your family are eligible.

    If you feel unwell, please stay at home. If you have symptoms of COVID-19 or a positive swab test, please stay at home and away from others. And notify the government personnel of the first pass to conduct another virus test, and do not attend the party.

    Of course, nowadays, you must wear a mask before going out. This is for the health of you and your family and friends.

    You need to wear a mask when taking public transportation, including buses and airplanes.

    Of course, party us

    Gather in an outdoor or well-ventilated place.

    According to experience, the most likely way of transmission of the virus is through saliva or droplets. Therefore, during the epidemic period, try to avoid contact with others and face-to-face conversations.

    During the party, we should pay attention to eating clean cooked food and boiling water.

    Ask the party host to try not to choose to eat some wild, uncommon, and strange food.

    At the same time, the weather is volatile, and your handsome colleagues pay attention to adding or removing clothing.

    Finally, Cell Medical recommends minimizing unnecessary gatherings.

     

    The latest mutation of the new crown epidemic has increased the risk of transmission.

    Infectivity may increase by 500%! Powerful mutant strains broke out in various countries in the world!

    On the 27th local time, several countries and regions, including the United Kingdom, Germany, Italy, and Israel, discovered the new variant “Omicron” (Omicron) of the new crown.

    At this stage, countries around the world have tightened their epidemic prevention measures at different levels.

    The Israeli government announced that it will gradually prohibit all foreigners from entering the country on the evening of the 28th local time. Resolutely putting an end to the spread of the “new coronavirus mutant strain Omi Keron” has become a new starting point for epidemic prevention worldwide.

    Authoritative American experts think: “The infectivity of the new mutant strain may increase by 500%.”

    On November 27, WHO announced that the new mutant strain discovered in South Africa was named Omicron.

    On the 26th local time, the Federation of American Scientists emphasized that in comparison with the Delta mutation, the total number of “bad thorn gene mutations” in the new mutation was twice that of Delta.

     

    “The B.1.1.529 variant is likely to have a strong charisma of 500%, which is by far the most surprising statistic.”

    On the 26th local time, the United States announced that it will gradually restrict the citizens of South Africa and seven other non-US African states to travel to the United States from the 29th.

    Previously, the United Kingdom, the European Union, and many other places have called for the suspension of flights originating from African countries.
    The new mutant new coronavirus “Omi Keron” first discovered in South Africa has spread rapidly

    According to foreign media reports, in Gauteng Province, where the population of South Africa is more concentrated, 90% of the recent increase in virus cases is related to this strain. The Israeli Ministry of Health issued a statement on the 26th stating that the first case of “Omi Keron” virus infection was found. The case came from Malawi, Africa, my country. The Belgian Minister of Environmental Health, Van den Brock, confirmed that the host country has found the infection case of the mutant strain “Omi Keron”. According to reports, this is also the first diagnosed case in Europe.
    The first case of Omi Kiron strain infection occurred in Italy…

    The spread of new mutant strains is astonishing, which has aroused great vigilance in all countries!!!

    Facing the epidemic, but the company arranges to travel, what should I do?

    Of course, the best option is to refuse a business trip. But often this is not something we can decide.

    Everyone is based on the following suggestions to alleviate the spread of COVID-19 to protect themselves and others.

    The more processes you use to mitigate the spread of COVID-19, the safer you will be. When it comes to avoiding the spread of COVID-19, no step is perfect.

    1. Reduce your risk of COVID-19

    2. Actions and natural environment maps with lower risk and higher risk.

    3. Proposals for participants and theme event planners: COVID-19

    Vaccination. The COVID-19 vaccine is one of the appropriate ways to avoid being infected or spreading COVID-19.
    If you are not vaccinated (including children)

    Maintain a minimum distance of 6 inches from people from other homes.
    When you cannot maintain a 6-inch distance from others, please wear a mask in the room and outdoors.

    If you are vaccinated or not vaccinated, Cell medical strongly recommends that you:

    1. Wash your hands frequently, maintain your hygiene, and open windows every day for ventilation

    2. Try not to go out, if you go out, try to wear a mask

    3. Try not to hold parties and avoid contact if it is not necessary

    4. Pay attention to eating habits, eat more fruits and vegetables, exercise, and keep a good sleep

    5. Cover your nose and mouth when sneezing, and don’t spit anywhere

    If possible, work from home.
    Clean and disinfect the surface.

    Please do a nasopharyngeal swab test and isolation work before going home. For the health of you and your family.

    About COVID-19 Swab Test

    The new crown virus has mutated continuously.

    From Delta to Omi Keron, the COVID-19 virus has continued to mutate, and the global epidemic is prevalent at a high level.

    Canada announced that all entry personnel from all countries except the United States are required to be tested for the new coronavirus.

    At this time, whether you are leaving the country or entering the country.

    I even worry or doubt whether I have contracted the coronary disease.

    Perhaps understanding the new coronavirus test has become a compulsory course for most people.

    What is the new crown swab test, how to collect a nasopharyngeal swab?  Is nasal swab sampling painful?  If your test result is positive, what do we need to do?  Why do most virus tests choose to flock swabs? Is nasopharyngeal swab accurate? Should you be tested for nasopharyngeal swab samples?

    We talked with Dr. Li of Cell medical to learn more.

    What is the COVID-19 test and what are the test methods?

    Nucleic acid detection (RT-PCR Test) method, antibody detection, and antigen detection.

    A swab test simple, effective, and fast way to detect COVID-19.

    Including nasopharyngeal swab testing and oropharyngeal swab testing.

    Medical staff will use flocked swabs to take samples from the nose and throat and put them into the virus sampling tube.

    There are two types of swab sample testing: molecular test (PCR) and antigen test.

    How to perform a COVID-19 nasal swab test?

    The COVID-19 nasal swab test involves inserting a 6-inch flock (a long stick with a very soft brush) into the cavity between your nose and mouth (nasopharynx).

    The medical staff inserts the flocking swab into each nostril for about 15 seconds and rotates it several times to collect enough samples for testing.

    The samples are then sent to the laboratory for testing, and our test results are usually known within or within the next day

    Since the nasopharynx is in a sensitive position of the body, it will produce a lot of very strange sensations.

    On the one hand, the swab is inserted deeply into your nose and it irritates the lacrimal glands.

    At this point, you don’t know if you are moved to tears or you are crying in pain.

    The nasal swab test is not very painful, but it is very uncomfortable. Some people may have nausea during the nasopharyngeal swab test. Nasal swab painful.

    Because the swab will also touch the back of your throat, this reaction is normal.

    Whether it is tearing or nausea, nasal swab testing is a common phenomenon.

    Don’t worry, everything is normal.

    Are there other types of COVID-19 swab test methods available?

    Yes, an oropharyngeal swab is one of the options.

    Of course, if you want to experience another feeling, an anal swab test is also a good choice.

    But they are not as sensitive as the COVID-19 nasal swab test.

    Israel’s development of the new coronavirus “saliva detection method” saliva detection still needs scientists to confirm on a larger scale. There is no conclusion yet, but it is promising.

    In addition to nucleic acid testing for the detection of viral genetic material, there is also antigen testing.

    Currently, nasal swab testing for COVID-19, including nucleic acid testing, is still the best choice.

    How about the covid test kit at home? Are their results reliable?

    The home covid test kit sounds very attractive.

    Home covid test usually refers to individuals collecting samples of themselves or their family members through sampling swabs.

    We put the collected samples in test tubes with a virus transport medium, and then transport them to the testing facility.

    Although you can use the Home covid test kit to test COVID-19 safely and comfortably in your own home.

    However, Dr. Li suggested that it should be carried out at a professional testing institution.

    Because the quality of the samples we collect and the integrity of the samples during transportation will affect the sampling results.

    How accurate is the nasal swab test for COVID-19?

    How to obtain a precise nasopharyngeal swab specimen?

    Polymerase chain reaction (PCR) uses a piece of DNA as a template.

    Then, with the participation of DNA polymerase and nucleotide substrate, the DNA is amplified to a sufficient amount for structural and functional analysis.

    Pcr nasal swab test can be said to be very sensitive.

    Scientists use PCR technology to amplify a small amount of RNA in the sample into deoxyribonucleic acid (DNA) and replicate it until COVID-19 (if present) is detected.

    The following may affect the accuracy of PCR nasal swab sampling.

    1. Smoking, drinking or chewing gum 30 minutes before use may also interfere with the test results.

    2. Touching the swab with the hand or other objects and using the tip of the cotton swab will affect the accuracy of the detection.

    Of course, the professionalism of the most important sampling personnel, we have to choose a professional testing agency for testing. And professional VTM Kits.

    What should I do if the new coronary pneumonia nasal swab test is positive?

    Very bad news!

    If the COVID-19 nucleic acid test is positive, a single room isolation treatment should be carried out immediately.

    Consultation by in-hospital experts or attending physicians will conduct multiple tests.

    Under the premise of ensuring safety, the patient is safely transferred to a designated hospital for diagnosis and treatment.

    Don’t worry. You need to actively cooperate with treatment

    Otherwise, life is likely to be in danger, and large-scale infections will also occur.

    In addition, proper physical exercise should be carried out in life to enhance the individual’s immunity. Colds and fatigue should be avoided.

    Don’t do strenuous exercise, so as not to aggravate the disease.

    A friend around me was infected with COVID-19. But my nasopharyngeal swab was negative. Is there any way to confirm that I have had it or am I immune to it now?

    Certainly.

    Antibody test, also called serological test, can detect the antiviral protein IgM and IgG antibodies produced by your immune system in the blood.

    What are the types of samples for serum antibody testing?

    It is generally blood, including serum, plasma, and whole blood.

    Do a good Virus Swab Test, Epidemic is not over yet.

    Winter has arrived, affected by the new crown pneumonia epidemic in Europe. Such as Cuba, the Netherlands, Germany, the United Kingdom, etc., the epidemic is continuing. More and more European countries have recently stopped restarting and tightening anti-epidemic measures. After the outbreak, European experience proved that: “Dynamic zero adjustment has been mastered” . “continuous changes in temperature rise have been controlled.” Advantages and captures “return to zero” and “constantly switch between limiting adjustments”.

    COVID-19 mutant virus Omi Kiron strain has spread to all provinces in South Africa.

    South African President Ramaphosa said on the 28th that in the next few weeks.

    There may be a fourth wave of new crown epidemics in South Africa.

    And the public should do a new crown virus sampling swab test as soon as possible and get the new crown vaccine.
    In the evening, Ramafosa said in a televised speech that in the past 7 days.

    The number of confirmed cases of the new crown in South Africa has risen to an average of 1,600 per day, while the positive rate of new crown virus testing in South Africa has risen from approximately 2% to 9% in the previous week.

    If the newly emerging confirmed cases continue to rise, South Africa may enter the fourth wave in the next few weeks.
    Lamafosa said that the recently emerged mutated virus, Omi Keron virus, has spread to all provinces in South Africa.

    At present, immunization is still the most important means of protecting oneself and others.

    The emergence of the Omi Keron virus has sounded a wake-up call for the whole world.

    Several countries, including South Africa, have recently reported confirmed cases of Ome Keron, and the World Health Organization listed the virus as a “variety of concern” on the 26th.

    About the European epidemic

    European experts believe that the recent occurrence of the “epicenter” of the global epidemic in Europe is related to factors such as disease awareness, premature “unblocking”, and insufficient vaccines. The most critical factor-the effect of excessive pendulum movement, which swings from side to side at a strict angle. We must do a good job in the swap test of the COVID-19.

    Herd immunity？

    Doing a good job of a virus swab test, testing and vaccination is the top priority.

    At the beginning of the disease outbreak, Patrick Valence, the chief scientific adviser of the United Kingdom, put forward the theory of “herd immunity”. Now in the world, the EU has completed 7% of the population protection range of about 6%, and still cannot solve the fourth wave of epidemics.

    The proliferation of medical resources film festivals appeared. The incidence is higher in the northern region. 79% of people abroad have received local injections. The number of the above cases has reached 9.8 million, and the proportion of the British population is 14.6%. New highs since the beginning of winter, the peaks of the virus wall in various states have taken turns, and no emergencies have occurred. The theory of “in the iron face, group immunity” has broken down.

    “Coexisting with the Virus” Nonsense.

    Mistakes in the fight against the virus continue to disrupt growth and even increase risks. From the beginning of the new century, the “labor shortage” and supply chain crisis in many countries can end this. Over the past year or so, Europe has had to return and fall in the policy choices of “severe cold and epidemic prevention” and “economic recovery”. The vicious circle of “high control-unraveling-epidemic rebound-re-management”.

    However, as the life expectancy of relevant countries or regions has dropped significantly, the problems that gradually emerge after the outbreak of the disease will have a more severe and instantaneous impact.
    It has achieved great success by adhering to the goal of zero-clearing the epidemic. Even eager to announce “coexistence with the virus”, trying to adopt a third response method under the situation of repeated zero-sum dynamics.
    But, there will be such a road there? The result of choosing to “coexist with the virus” at this stage is nothing more than harming more people’s lives.
