To talk to you in detail
Covid nucleic acid test!

But in the face of the “nucleic acid swab test”
This unfamiliar and familiar word
Do you have many questions?

Do you want to do a nucleic acid test when you go back?

Will it be difficult to make an appointment for nucleic acid testing?

How long does it take to get the results of a nucleic acid test at the hospital?

Should I Swab My Throat or Nose for Rapid COVID-19 Tests?

To answer your questions.
Today.
I’m going to tell you.
Those things about nucleic acid testing.

01. What is nucleic acid detection?

At present, nucleic acid detection is the main method for laboratory diagnosis to determine whether a patient is infected with the new coronavirus. It can achieve early detection, early diagnosis, and early treatment. Real-time fluorescent PCR can be used to detect throat swabs, sputum or blood samples. to covid nucleic acid, or detected by viral next-generation gene sequencing.

simply put

Nucleic acid testing is done by

After collecting human secretions

Tested by the instrument

to see if we have the new coronavirus in our body

If so, the test result is positive

On the contrary, if it doesn’t, it’s negative.

02. How to test the COVID swab?

“Sir, oropharyngeal swab, nasopharyngeal swab, and anal swab, which one to choose?”

How do you do a nasopharyngeal swab?

Nasopharyngeal swabs must be performed with the patient sitting upright with the head in an upright position, as this allows for easy visualization and access to the nasal floor perpendicular to the central axis of the patient’s face.

Insert the swab into the patient’s nose and align it parallel to the nose and the base of the septum. As long as there is no obstruction in the nasal cavity, the swab continues to move in this direction until it reaches the nasopharynx, at which point the tester feels resistance.

Once the swab reaches the nasopharynx, a gentle rotation and two complete 360-degree rotations are recommended to allow secretions from this area to be absorbed.

Once the swab is removed from the patient’s nose, it is immediately inserted into a viral sample containing a viral transport medium. The handle of the swab extending through the opening of the vial was broken off to allow the tube to be closed.

So
Now that there are oropharyngeal swabs and nasopharyngeal swabs
Why add anal swabs?
To answer your questions
Let’s take a look at their respective advantages and disadvantages

The specific operation of the anal swab is as follows:

Soak a flocked swab in saline, insert it 2-3 cm into the anus, wipe from the folds around the anus, or rotate it gently inside the anus, and insert it into a test tube containing saline.

anal swabs

For fecal swab cultures, all of the above requires the use of sterile equipment and placing the swab in a sterile tube.

So
Now that there are oropharyngeal swabs and nasopharyngeal swabs
Why add anal swabs?
To answer your questions.
Let’s take a look at their respective advantages and disadvantages.

Oropharyngeal swab: relatively simple to operate, less irritating, suitable for large-scale screening. Therefore, the nucleic acid test of oropharyngeal swabs is mainly used in the screening of new coronary pneumonia for the epidemic-related population, which is used in the routine nucleic acid test clinic of the First Affiliated Hospital of NTU.

Nasopharyngeal swab: The technical requirements are high, the human body does not feel comfortable, and the accuracy rate is higher than that of the oropharyngeal swab. However, for some asymptomatic or mildly infected people, the condition recovers quickly after infection, and the pharyngeal nucleic acid may not be detected in 3 to 5 days.

Anal swab: high accuracy, reduce missed diagnosis. The study found that the duration of nucleic acid-positive feces or anal swabs of some infected persons is longer than that of the upper respiratory tract. Therefore, anal swab tests will be carried out for key groups such as isolation points or some imported overseas.

In conclusion.
The three swabs have different lengths.
If you have to test an anal swab.
Don’t be shy.
Whatever the swab,
It is a good swab that can accurately identify the virus.

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.

What is a Medical Swab

In the COVID-19 sampling, medical flocked swabs are the most commonly used testing method.

Application: oral mucosal cells, oral microorganisms, virus sampling and transportation, DNA/RNA collection, throat sampling, cervical sampling, nasopharyngeal sampling and other fields.

In addition, we can also use medical cotton swabs for the collection and transportation of DNA for paternity testing.

As well as the collection, preservation and transportation of flu specimens.

According to the material, medical swabs can be divided into cotton swabs, foam swabs, non-woven swabs, flocked swabs and other products. Among them, the market share of cotton swabs is higher, reaching 76%.

According to the application field, medical swabs include gynecological, cervical and vagina sampling swabs; oral, nose, and pharynx sampling swabs; laboratory test sampling swabs; virus and bacteria sampling; disposable sampling swabs; sterile cell sampling And other products.

However, due to the influence of new coronary pneumonia and the popularization of nucleic acid testing, the proportion of medical swabs used for specimen sampling is increasing.

With the continuous improvement of medical conditions in developing countries around the world, the application demand for medical swabs is on the rise.

In 2020, the global medical swab market will reach 400 million U.S. dollars, with an output of about 38.4 billion pieces.

Moreover, due to the development of the world economy, the price of medical cotton swabs has shown an upward trend.

Choose the right medical swab

Swabs are one of the most commonly used disposable devices in the medical industry. But how do you know which application to choose? We have put together a brief overview on how to choose the right medical swab for your specific needs.

Cotton swab

The tip of American pharmaceutical-grade spun cotton fiber has become the standard for applicators for all applications from basic patient care to crime scene investigation.

With strong water absorption capacity, softness, low cost and safety, the performance of the cotton swab is consistent and reliable.

However, it is generally not recommended to use cotton swabs for specimen collection.

why? The characteristics of this natural material prevent the sample from being effectively released, and the naturally occurring fatty acids in this material interfere with the processes used in microbiology and DNA extraction and have proven harmful to organisms.

Rayon cotton swab

"<yoastmark

Rayon is a synthetic fiber made from wood pulp.

Although classified as synthetic fiber, it is actually a natural material.

Unlike cotton, artificial fiber removes materials that may sample or react to samples for transportation and processing during the production process, so it is usually used to sample for diagnostic tests.

Polyester fiber swab

"<yoastmark

Swab head material adopts polyester filament winding.

Polyester fiber is used for microbial collection, rapid diagnosis and PCR detection.

The polyester scraper has a higher release rate, but its cost is higher than cotton swab and rayon swab.

Foam tip swab:

Foam swab

Foam swab

The swab made of medical polyurethane is a very good diagnostic material, especially suitable for cell sampling.

The number of holes on the surface is generally 100 PPI (holes per inch).

This material has good hydrophilicity and poor absorption of hydrophobic substances.

Used in occasions where resistance to chemical corrosion is required, and it is also used for DNA and microbial sampling.

Synthetic swabs (rayon and polyester) are used to collect bacterial culture specimens, rather than cotton swabs that may contain inhibitory or toxic substances.

Flocked swab:

flocked swabs

flocked swabs

First developed flocking technology for cosmetics and industrial production.

Because of the planting process and the use of multi-head bifurcated polyester fiber materials.

The flocked swab has a very high absorption and release rate, and it is also effective for molecular sampling and absorption.

Some institutions designate to conduct research on nucleic acid sampling and certain genome analyses.

At present, the development of swabs not only reflects the changes in the materials of sampling swabs, but new demands in the fields of nursing, testing, and scientific research have led to the multi-dimensional development of swabs.

What’s The Difference Between COVID-19 Rapid and PCR Tests?

What’s The Difference Between COVID-19 Rapid and PCR Tests?

As New Year’s Day approaches, the number of new crown infections is also rising. Therefore, once you have symptoms of infection. Or you are exposed to the new coronavirus. If you are going to an environment with a high risk of infection.

You must continue to be tested.

Currently two COVID-19 detection methods-polymerase chain reaction (PCR) test (also known as reverse transcription-polymerase chain reaction test) and a rapid antigen test.

So, which detection method should we choose? What is the difference between the two?

On the COVID-19 website, terms such as PCR, rapid test, and antibody test are difficult to understand and which one is correct for you. In this article, our goal is to explain the difference between the two most common tests for diagnosing COVID-19: rapid antigen test and polymerase chain reaction (PCR) test.

Rapid antigen test

Antigen test (often called rapid test). This test detects protein fragments specific to coronavirus. We can do the antigen test in a clinic, doctor’s office or hospital. The turnaround time for results is usually very fast, and in some cases, we can get report results within 15 minutes. There are usually false negatives (the results indicate that the patient does not actually have a coronavirus) or false positives (the results indicate that the patient does not actually have the coronavirus).

If you feel unwell and have undergone a rapid negative test, you may need to undergo a PCR test for further confirmation. However, when someone is at the peak of infection, rapid antigen testing usually provides accurate results because this is when the virus levels in the body are highest.

The rapid antigen test is usually used as a screening tool to detect that you may be infected with the new crown, but PCR monitoring is required to confirm the final result.

Although a negative rapid antigen test result does not necessarily mean that you are not infected, it at least protects your contacts than not testing at all.

PCR TEST

PCR swab tests are similar to rapid tests in several respects because they can be used in symptomatic or asymptomatic patients and can be tested with nasopharyngeal swabs.

The swab test is considered the “gold standard” for SARS-CoV-2 detection. This test actually detects RNA (or genetic material) unique to the virus, and it can detect the virus within a few days of infection, even for those who have no symptoms. This test can be performed in a clinic, hospital or even in your car. The turnaround time is longer, generally in the range of 2-3 days, but the result may be within 24 hours. When the demand is high, the result may take a week or more.

What if the rapid test is negative but there are still symptoms?

The current recommendation is that if you still have symptoms and the rapid test is negative, you should have a confirmation test (PCR test). This is especially true if you have high-risk exposures. High-risk exposure is considered to be contacted with a COVID-19 positive individual for more than 15 minutes within 24 hours, and the distance between you and the individual is no more than 6 feet.

What kind of test should be done? When will it be done?

RT-PCR (reverse transcriptase-polymerase chain reaction) detection if the following situations occur:

1. Symptoms of new crown infection appear.
2. Having contact with people infected with the new crown.
3. The rapid antigen test result is positive, and PCR identification is required.
4. The Ministry of Health requires testing before lifting the quarantine.
5. The Ministry of Health requires that an inspection must be carried out before obtaining permission to travel to a certain area.

If you want a quick antigen test:

1. Have a plan to go to a place with a high risk of infection.

2. Contact with high-risk groups (such as the elderly) and hope to protect them.
3. You have symptoms of COVID-19, but you cannot go to the PCR test site.
4. Activities with a large number of participants in the field, if indoor activities are carried out, the risk of infection is greater.
5. Check whether you have the SARS-CoV-2 virus as soon as possible.
6. Participate in regular COVID monitoring projects.

    How does a Covid Mouth Swab Test work?

    I went for a swab test for the new coronavirus the day before yesterday, and the result came out yesterday and it was negative. Some friends asked me, is the throat swab test painful? How to do it? What are the types of COVID-19 tests? What COVID-19 test is more accurate? Today, Dr Lee came to give everyone a popular science.

    You can use a variety of tests to determine whether you have COVID-19. Some tests are collected by mouth swabs, and some are collected by nasal swabs or saliva. In the experiment, an oral flocked swab was used to collect samples from the oral cavity for oral inspection. This is different from a saliva test, which spits out saliva into a small container.

    On this page, you will learn:

    1. What is a mouth swab? Painful? 
    2. How to do a mouth swab COVID-19 test
    3. What are the types of COVID-19 tests?
    4. What COVID-19 test is more accurate?

    What is a mouth swab? Painful?

    The COVID-19 test is the most important way to diagnose the new coronavirus. Nucleic acid is the genetic material RNA of the new coronavirus. The nucleic acid test is to check a certain segment of RNA. If it is positive, it means that you are infected with the new coronavirus.
    According to different sampling sites, nucleic acid detection can be divided into many types, such as throat swabs, anal swabs, tracheal secretions, alveolar lavage fluid, and so on.
    Among them, throat swabs are the most commonly used, and oropharyngeal or nasopharyngeal secretions are taken for laboratory tests.

    Oropharyngeal swab, the inspection process is very fast, no more than 10 seconds, only needs to open the mouth, and the staff uses a cotton swab to take a sample in the oropharynx.

    When sampling, there will be a slight pain, and when the throat is stimulated, there will be a feeling of vomiting.

    But the feeling is not strong, and it will be fine for a while.

    According to British colleagues, the nasopharyngeal swab is more uncomfortable, and the pain will be greater because the nasopharyngeal swab needs to be completely pricked into the nose. Learn more about nasal swabs Please click here

    How to interpret the results of the Oral swab test?

    Nucleic acid(COVID-19) testing usually produces results within 24 hours. If you check today, the results will be known the next day. The results are nothing more than two cases, negative or positive.

    Does negative mean there is no infection?

    It is not 100% certain, because nucleic acid testing has a certain probability of false negatives. For example, in the early stage of the disease, the virus content is very low, and it may not be detected, or the sampling is not taken properly, and the sensitivity of the detection reagents, operation Whether it is standardized or not, etc., are affected by many factors.

    How to do a mouth swab COVID-19 test

    How to use mouth swab

    How to use mouth swab

    There are different ways to do a COVID-19 mouth swab:

    • 1. The patient needs to sit with his head back, open the mouth, and then remove the nasal cavity and the secretions on the oral surface.
    • 2. The collector uses a special tongue depressor to fix the patient’s tongue, and then cross the throat with the collecting tool, and the tonsils directly to the position where the specimen is taken.
    • 3. After repeated wiping of the collection table, mucosal cells can be directly extracted.
    • 4. Take out the collected throat swabs. Be careful not to touch the oral mucosa, tongue and saliva secreted by the oral cavity during this process to prevent inaccurate test results.
    • 5. Put the extracted throat swab into a special device and transport it to the laboratory for examination.

    You may need to take specific steps before the test so that the results are as accurate as possible. If you need to book an appointment, ask if there’s anything you should avoid on the day of your test. Some types of tests that use saliva require that you don’t eat, drink, smoke, brush your teeth, or chew gum 30 minutes before the test (FDA, 2020).

    What are the types of COVID-19 tests?

    In the UK, when diagnosing COVID-19, there are usually two main types of tests:

    Molecular biology tests, such as PCR (polymerase chain reaction), are used to find viral genetic material.

    Look for the antigen detection of the virus shell.

    Either test can be done with a nasal swab or a mouth swab. Saliva can also be used for PCR detection (FDA, 2021a). Although saliva and oral swab tests may sound the same thing, they are actually slightly different. The saliva test requires you to spit into the tube, while the oral swab test is to wipe a sample in the mouth with a cotton swab.

    Nasal mucosal secretions follow the same rules, but the difference is that you or a health care professional collect the sample from your nose instead of your mouth.

    Another type of test is antibody testing (also called serological testing). These two data can’t tell you whether you are infected now but can tell you whether you have been infected before or if you have been vaccinated before. Antibody testing usually requires a blood sample.

    What COVID-19 test is more accurate?

    How to interpret the swab test results

    Nucleic acid testing usually produces results within 24 hours. If you check today, the results will be known the next day. The results are nothing more than two cases, negative or positive.

    Does negative mean there is no infection?

    It is not 100% certain, because nucleic acid testing has a certain probability of false negatives.

    For example, in the early stage of the disease, the virus content is very low, and it may not be detected, or the sampling is not taken properly, and the sensitivity of the detection reagents, operation Whether it is standardized or not, etc., are affected by many factors.

    With the continuous optimization of detection methods and the continuous updating of reagents, the sensitivity of detection is now higher, and the probability of false negatives is lower than before.

    If it is negative, there is a high probability that it has not been infected with the new coronavirus.

    For some high-risk groups, close contacts, and suspected clinically highly suspected cases, one negative may not be enough, and two, three, or even multiple tests may be required.

    Notice

    Even if you have been tested before, COVID-19 testing is difficult to cope with. But the test should be able to relieve stress and not cause stress.
    In any case, the knowledge of COVID detection technology is constantly changing. If you want to know if you want to be tested and how it works, we will help you at any time. Here is some information about oral swab COVID testing and other information to determine whether COVID-19 is COVID-19, you need to know.

    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.

    Speaking of a Covid sampling Swab. We believe everyone will not be unfamiliar at this time. Because the detection tool used at this time is a possible sample.

    Sample swabs directly contact our human organs, such as nasal swabs and throat swabs for testing. Therefore, the selection of the material of the sampling head is very important, and the material of the sampling head is related to the detection of the test.

    Omi Keron strain Covid Swabbing

    The team of Professor Huang of Nankai University discovered this through big data modeling and analysis.

    The infectivity of Omi Keron is about 37.5% higher than the infectivity of the new crown mutant strain Delta.

    The Netherlands and Brazil both reported cases of infection with the Omi Keron strain of the new crown virus on the 28th.

    To reduce the spread of the Omi Keron strain, all the people in Bots have recently appeared in the agency. The movement has a new crown for passengers in Bonawana, Malawi, Lesotho, Swaziland, Namibia, Mozambique, and Zimbabwe. Virus detection.

    On the 28th in Hubei Province, two cases of Miokeron strain occurred in the capital of Ottawa, Canada.

    Following reports of Omi Keron infections in some countries including a week later, this strain was infected with a mutant strain that “needs attention” on the 26th.

    The United Kingdom, Germany, Italy, Russia, and Australia successively reported cases of infection with this strain on the 2nd and 28th. Ireland, New Zealand, Australia, the United Kingdom, Canada, the Netherlands, and the Czech Republic have also reported relevant cases.

    For the spread of the virus strain, many countries have prepared measures and taken protective measures.

    How to obtain a nasopharyngeal swab specimen?

    Overview.

    Nasopharyngeal swab specimen collection of respiratory mucosal surface specimens is a method for the diagnosis of Covid-19 novel coronavirus in adults and children.

    This operation can also detect patients with suspected respiratory infections caused by other viruses and bacteria.

    There are no special contraindications for nasopharyngeal swab specimens. However, clinicians should treat the following conditions with caution: the recent history of nasal trauma or surgery, severe nasal septum deviation, chronic nasal obstruction, and severe coagulation.

    Preparation for nasopharyngeal swab specimen sampling.

    The nasopharyngeal swab is a special sampling tool, which consists of a sampling head made of soft plastic or flocked nylon. In addition to nasopharyngeal swabs, operators also need personal protective equipment (PPE) such as isolation gowns, non-sterile gloves, protective masks, and face shields.

    Before starting to use, please make sure that all virus sampling tubes are labeled, and the analysis application form is filled incorrectly.

    Nasal Swab Sampling Steps

    We recommended that patients with suspected Covid-19 type coronavirus infection wear masks.

    The patient took off the mask and blew his nose with a paper towel to remove excessive secretions from the nasal passages.

    Take out the tissue. Slightly lift the patient’s head so that it can wipe into the nasal passage. Ask the patient to close his eyes to alleviate the slight discomfort caused by the operation.

    Along the nasal septum, gently push the swab above the bottom of the nasal passage forward until you feel a sense of resistance indicating that the swab has reached the nasopharynx.
    Insert the swab in the nostril parallel to the upper jaw.

    If resistance is encountered during pushing the flocked swab, the scraper should be withdrawn, try to adjust the angle and then push again, at the same time closer to the bottom of the nasal passage.

    The depth of the nose insertion should be equal to the distance from the nostril to the opening of the external auditory meatus. CDC recommends keeping the sampling head for a few seconds after it reaches the nasopharynx, allowing the sampling head to absorb the secretions, and then slowly rotating the swab to discharge it slowly (people who have done nasopharyngeal swabs will appreciate which kind of sourness Cool feeling). Your institution may also recommend sampling for a few weeks after exiting the spin. Ask the patient to wear a mask.

    Nasopharyngeal swab specimen processing.

    Open the sampling tube with virus transport medium, put in the flocking swab, fold out the sample tube in the groove, and discard the tail. Tighten the label sampling tube cover, and wipe the sampling tube with a sterile wipe.

    Then place the sampling tube in the biohazard bag opened by the assistant. Some departments may require you to put the samples back in their original packaging and then send them for inspection. According to CDC guidelines, process the swab sample directly, or put the sample in a preservation solution or store it at room temperature.

    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.
