COVID-19: Main Symptoms

The three main symptoms of “new crown”: are fatigue, brain fog and muscle pain, the specific manifestations vary from person to person. Other more common persistent symptoms include shortness of breath, chills, body aches, headache, joint pain, chest pain, cough, and persistent loss of taste or smell.

 Forgetfulness, anxiety: “I feel useless”

Many people with long-term symptoms report cognitive impairment or memory loss that affects their ability to make everyday decisions, speak, follow directions and drive, and impair their quality of life.

Xiao Liu (pseudonym) works in British media. Three years ago, he suffered from depression. He largely recovered before contracting Covid-19 in November 2021 and has stopped taking antidepressants. But after she contracted Covid-19, the depression returned. The doctor assessed and judged that one of the symptoms of the new crown-brain fog persisted.

“After I got the new crown, I felt that I was ‘brainless’, I didn’t want to do anything, and I was extremely anxious.”

It starts with cold-like symptoms, headache, cough, fever, and loss of taste and smell. There are also chest tightness, shortness of breath, fatigue, insomnia, loss of appetite, forgetfulness, inability to concentrate, unresponsiveness, anxiety, etc.

“The overall condition is not good, and the weight has lost four kilograms”

After Xiao Liu fell ill, the children became sensible. I get up every morning looking for a school uniform to wear, and my 11-year-old will scramble eggs, eat breakfast, and go to school alone. My brother was hungry at night, so he cooked instant noodles and ate them together.

Xiao Liu remembers coughing for three weeks, being bedridden for a month, and then taking a long sick leave of more than three months.

“I couldn’t get out of bed to cook at all. The children ate takeaways every day, and my mouth ulcers had developed for a long time. Fortunately, some friends helped us and often brought us home-cooked food. At that time, the volunteers in the community even gave me anti-inflammatory drugs. Depression. Come to my house and make sure I take it on time. My family doctor advised me to call my psychiatrist again.”

“The biggest motivator for me was the several home visits from the social worker in charge of child welfare. The kind help made me extremely anxious and insomniac, and I felt like an incompetent mother who couldn’t do even the most basic things to take care of her children.” Covid has cost me! It’s unacceptable to me.”

“Regular doctor consultations and cordial greetings from unit leaders also made me feel like I was a burden. I didn’t want to be sick all the time. Everyday burnout and bedridden made me feel like I was useless.” “

For a long time, Xiao Liu felt that he had Alzheimer’s disease. Can’t remember anything, looking for something every day. It takes a few repetitions to understand what the doctor says. Sometimes after calling in the morning to confirm, call in the afternoon to ask.

“Sometimes I don’t know if I have taken medicine or not. Once I enter the kitchen, I forget what I am doing. I look at the pills with a water glass and ask myself if I just took the medicine or not?”

Because of the confusion caused by many small things, Xiao Liu deeply doubts his ability to do things. She feels that she must first learn to forgive herself and accept herself who is often tired and forgetful now.

Xiao Liu said that now he wants to make himself happier and more optimistic by doing one small thing every day. Doctors want to taper off antidepressants over a year.

Fatigue: “Three hours of sleep when I get back from the store”

Severe fatigue is by far the most common symptom of COVID-19. Other symptoms include muscle pain, hearing and vision problems, headaches, loss of taste and smell, damage to the heart, lungs, kidneys, and intestines, diarrhea, and mental health problems, including depression, anxiety and distraction, and stupor.

Before being diagnosed with “coronavirus”, she had been suffering from persistent fatigue, fever, and loss of smell and taste for months, for which she consulted several doctors of different specialties.

At first, my temperature rose slightly, I felt dizzy, and then my throat started to hurt. A day later, my fever reached 38.5°C. 

Later, I went for a checkup and received treatment. 

After three weeks of conventional viral infection treatment, tachycardia was found, while fatigue symptoms did not decrease.

Frequent blood tests, blood pressure measurements, and lung monitoring are performed. After taking antibiotics and vitamins for three weeks, the treatment failed, and he underwent ENT, pulmonology, cardiology, virology, rheumatology and immunology tests. Found chronic sinusitis, and heart adhesion, but not sure if it is caused by the new crown, it was still there before.

After a month, blood cell counts stabilized, but mental and physical fatigue and fever persisted.

For seven months, I was unable to concentrate, disoriented, felt hot, shivering, tired, didn’t know when it was going to pass, and felt scared every day.

At the doctor’s advice, make a “resurrection” plan, start walking, but take breaks from time to time, sleep at least three hours after going to the store or spend an hour in front of the computer.

Feeling changes, headaches, fatigue and brain fog are just a few of the symptoms of ‘coronavirus’

 Cognitive Function and Brain Fog: “IQ Decreases…”

“I’m not back to normal, from a cognitive standpoint, I’m not back to where I was before the coronavirus, in terms of focus, agility, flexibility… a year and a half later, I feel like I’ve only lost 30-40 %”. she says. % has been restored. I’m not the same as before, my IQ has dropped. “

“After a year and a half, after a lot of hard work, a lot of self-discipline, and all things considered, my condition has improved. I have anxiety (cognition) and I won’t fully recover, but I’m slowly accepting the possibility.”

COVID-19 Testing Sampling

COVID-19 Testing Sampling: Introduction to Throat Nasopharyngeal Swab

 Sampling for COVID-19 Testing: Introduction to Nasal Swabs, Pharyngeal Swabs, Nasopharyngeal Swabs

1. Material introduction:

1. Flocked swab: It is made of nylon fibre crowding modern technology, and also the front end is coated with nylon brief fibres repaired in a vertical manner so that there is no absorption hole in the whole tasting area of the tasting swab. As well as the sampling example, will certainly not be scattered as well as preserved in the fibers. Which promotes much faster and also a lot more efficient elution. Traditional cotton swabs can not entirely collect and also elute samples, while flocked swabs can elute 95% of examples. widely used.

2. Cotton Swab: The cotton bud is made from sterilized cotton wrapped around a wooden stick or a plastic pole. Because the all-natural product of cotton has a reduced release rate to the example, and also several of the natural fatty acids in it will harm microbes, the, even more, are much less as well as much less used for sample collection.

3. Rayon Head Swab: Rayon is a synthetic fiber made from wood pulp. Although categorized as an artificial fibre, it is basically a natural material. It is often the standard for diagnostic testing.

4.  Polyester Fibre Head Swab: The head product of the polyester fiber swab is made from polyester long fiber winding, which was very first presented in the field of medical screening by DuPont. Polyester fibres for microbial collection, rapid diagnostics, and also PCR screening. Swabs have a high launch price yet are extra expensive than cotton and also rayon swabs.

5. Foam Tip Swabs: Swabs made of medical quality polyurethane are superb materials for diagnosis, especially for cell sampling. This product has great absorption of hydrophilic substances and inadequate absorption of hydrophobic compounds. For some circumstances that need resistance to chemical rust, and also for DNA as well as microbial testing.

2. Introduction of sampling site:

Nasal Swab: Sampling of the nasal cavity.

Throat swab: Sampling of the throat area.

Nasopharyngeal swab: Sampling from the nasal cavity to the throat.

3. Safety factor and material:

Ordinary people can operate it. The new crown self-test products on the market generally use nasal swabs, and Foam Tip fibre heads are the first choice.

Throat swab: Professional operation is required, because the throat is more prone to injury, flocking swabs are the first choice.

Professionals must operate it, and it needs to be very careful from the nose to the throat. Generally, Westerners are easier to accept, while Orientals are less acceptable.

COVID-19: Will The Pandemic End in 2022?

COVID-19: Will The Pandemic End in 2022?

Only one month after the US lifted the mask order, Philadelphia will usher in a mandatory mask order again.

Beginning April 18, local time, more than 1.6 million Philadelphia residents must wear masks again when entering indoor public places. Philadelphia became the first major U.S. city to impose a mask mandate as cases rose again.

On April 13, the World Health Organization (WHO) New Crown Pandemic Emergency Committee held a meeting. After discussion, it was determined that the new crown pandemic continued to constitute a “public health emergency of international concern”, and countries were advised to prepare for it at any time. Do a good job in vaccination and PCR swab testing.

WHO Director-General Tedros Adhanom Ghebreyesus said: “It’s far from the time to let our guard down.”

According to the latest data from Johns Hopkins University in the United States. The number of confirmed cases of new coronary pneumonia in the world has exceeded 500 million. And the number of deaths has exceeded 6.1 million.

Endorsed by the WHO, in other words, one in 16 people in the world will carry the covid virus.

Since December last year, Omicron has been rampant around the world, with more than 200 million new confirmed cases worldwide in 2022.

500 million, or 5 billion?

At the same time, many experts and even the WHO believe that the number of truly infected people in the world is far more than 500 million, and may even exceed 5 billion.

Not to mention India, Africa and other countries and regions with poor medical conditions, weak testing capabilities, and chaotic management, even in the United States, the CDC has previously acknowledged that the number of infections reported nationwide is estimated to be less than 1/4 of the actual number of infections.

So, can the covid-19 stop this year?

COVID-19: Will The Pandemic End in 2022?

Faced with this question, WHO spokesman Tarik Jasarevic did not respond positively, but reiterated that in order to end the acute phase of the new crown pandemic, scientists have developed an effective epidemic prevention and control response.

Viral Transport Medium With Swab

Viral Transport Medium With Swab

He also warned: “As the new crown epidemic continues to spread on a large scale around the world, the emergence of more new crown variants and recombinant variants is foreseeable.”

Tedros said that the WHO is currently closely monitoring the development of BA.2, BA.4, BA.5 and other Omicron subtype strains, as well as the recombinant XE formed by the combination of BA.1 and BA.2 evolution.

BA series and X series, how dangerous?

Although the number of new cases around the world has been declining for three consecutive weeks. There are also some countries and regions where new cases are still climbing.

Many Asian countries are experiencing the Omicron wave for the first time. In South Korea, new infections and deaths have continued to climb since February.  The country now has the world’s highest daily average of new confirmed cases for a week. According to a Reuters analysis, South Korea currently has an average of more than 182,000 new confirmed cases per day, accounting for a quarter of the world’s newly confirmed cases.

Some European and American countries have experienced a wave of Omicron infection peaks at the beginning of this year, but the epidemic has recently rebounded.

In Europe, the daily increase of confirmed cases in France has shown a slow upward trend, and the seven-day average of newly confirmed cases in Germany has declined, but it is still at a high level. Reuters pointed out that the number of new cases in Europe is still huge, with more than 1 million new confirmed cases almost every two days.

At present, BA.2 is the main circulating strain in many countries, accounting for 94% of all gene sequencing.

While BA.4 and BA.5: Found in South Africa and many European countries.

Experts believe that if more people can be vaccinated and more people have the tools to fight the epidemic, then we can reduce severe cases and further reduce infections, thereby gradually ending the pandemic.

He also emphasized that it is very important to continue swab testing while the pandemic is still ongoing so that cases can be accurately tracked.

Flocked Swab

Flocked Swab

Nylon flocked swab

Made of nylon fibre flocking technology, the front end is coated with nylon short fibers fixed in a vertical manner.

Increasing the efficiency of collection and release of cellular and fluid samples.

So that there is no absorption hole in the entire collection area of ​​the swab.

The collected sample does not disperse and remains in the fibre, facilitating faster and more efficient elution.

Traditional spun cotton swabs cannot completely collect and elute the sample, while flocked swabs can elute more than 95 per cent of the sample collected.

So the use of flocked swabs has great advantages for a variety of sample collection applications.

Because most of the testing tools used for nucleic acid testing are disposable sampling swabs, we usually see more nasal swabs and throat swabs.

Improve analytical sensitivity, no sample residue, and speed up sample processing.

PS stickers come off easily. Suitable for cervical, nasopharyngeal, oral, forensic collection systems and DNA collection, etc. Individually packaged.

Flocked swabs are biocompatible and ideal for PCR work.

PCR is compatible, free of RNase and DNase, so the new flocked swabs are ideal and a good choice for scientists working with PCR technology.

Flocked swab sampling is more comfortable and easier to use;

CellMedical’s flocked swabs use the existing technology “spraying technology”, which is to vertically attach millions of nylon fibres to the head of the medical swab shaft through electrostatic charges in the flocking hair.

The vertical nylon fibres resemble a soft brush.

During sampling, the user will have no foreign body sensation.

In addition, different parts have different breaking points of the flocking swabs used, and the thickness of the swab rod is also different.

So there is a big difference in softness.

For example, for nasal swabs, the upper end of the swab rod is thin and soft, and the breaking point is also relatively back.

What to do before swab test

What to do before swab test

What to do before the swab test?

Why implement full coverage of DNA swab testing?

What should be paid attention to in DNA testing?

The latest statistics on the COVID-19  released by Johns Hopkins University in the United States on the 9th show that the cumulative number of confirmed cases in the United States has exceeded 60 million.

Nucleic acid detection is an effective method for precise prevention and control.

After the COVID infects the human body, it will multiply in the respiratory system.

Using a nasopharyngeal swab to detect sputum can determine whether the human body is infected with the virus, and can quickly and accurately “find out” the virus.

The recent spread of the epidemic has brought new pressure to epidemic prevention and control around the world. There are even reports of a country’s leader being positive for the new crown. Mexican president tests positive for coronavirus. The President of Paraguay has tested positive for the new crown. Poland: President tests positive for coronavirus. Brazil’s president tests positive for coronavirus. etc.

On the basis of continuing to perform nucleic acid testing on key groups of people, close contacts, etc., to identify the infection chain as soon as possible, block the transmission route, control the spread of the epidemic, and implement large-scale full nucleic acid testing, we must achieve early detection, early reporting, Early isolation, early treatment, active search for potential new coronavirus infections, and targeted prevention and control measures are also adopted to protect the health of the masses, ensure the rational flow of the population, and maintain the stable development of social and economic life order. It is very important. significance.

What methods are available for COVID swab testing?

Nucleic acid detection generally adopts the nasopharyngeal swab detection method, including nasopharyngeal swab detection and oropharyngeal swab detection.

At present, most hospitals and institutions in our city use oropharyngeal swabs.

This method is the least painful and more convenient to collect samples.

Is it painful to take a throat swab?

A throat swab is a method of collecting a specimen from the throat area, it is painless, mild nausea or sore throat method, which can be relieved or disappear quickly after collection.

Are DNA tests dangerous to humans?

There is no harm to the human body, only when the throat swab is collected, a slight foreign body sensation will be felt when the cotton swab enters the throat.

What should I pay attention to before and after the inspection?

Before detection

Before the nucleic acid test, it is best not to eat for 2 hours, otherwise, it will cause vomiting.
Do not drink water, smoke, drink, or chew gum 30 minutes before sampling.

Before the examination, reduce the number of swallowing movements, and do not do throat-clearing movements, such as expectoration and spitting.

For example: before the nasopharyngeal swab collection, the subject should provide the collector with the relevant past medical history or related matters.

Such as history of nasal surgery, nasal septum, blood disease, throat disease, or taking anticoagulant drugs.

Be sure to wear a mask before going to the test, take out the mask before the test, and put it on immediately after the test. You can prepare a spare mask, which can be replaced at any time after pollution.

Checking

When collecting oropharyngeal swabs, the subject should tilt his head back, relax as much as possible, take a deep breath, and open his mouth to make an “ah” sound, which will help reveal the throat, but symptoms such as irritating dry cough, nausea and vomiting may occur during this process.

Nasopharyngeal swab During the process of nasopharyngeal swab, symptoms such as swelling, itching, and sneezing may occur, which can be covered with a tissue or elbow.

After detection

Leave the collection site immediately after collection to avoid spitting and vomiting near the collection site.

You must pay attention to hand hygiene before and after the nucleic acid test.

You can wipe your hands with your hands, or you can use hand sanitiser, disposable alcohol, and disinfectant cotton pads.

 

Important reminder:

●Be careful to wear a mask, do not expose your nose and nose, do not take it off at will, or pull the mask to your chin.
●There should be an orderly queue, keep a distance of 1 meter, do not get together, do not gather.
●When waiting in line for a long time, pay attention to sun protection, sun protection, scientific hydration, and a reasonable diet.
● Try to avoid taking public transportation to the nucleic acid test sampling site.

The current situation of epidemic prevention and control is very complicated.
Every day, take care to protect your body.
Wear a mask and follow the epidemic prevention regulations.
Protect yourself and protect others at the same time.
New coronavirus pneumonia cases.
Please accept the general guidelines for prevention and control.
Daily Travel Prevention Control Guidelines.
Take the bus, take the subway.
To minimise contact, payment can be made using a transport card or a mobile app.
Avoid touching public facilities such as seats, armrests, car doors, and armrests with your hands as little as possible. If you do, do not touch your mouth, eyes, and nose directly with your hands, and disinfect your hands in time to avoid contact infection.

Hospitals and other places, after returning home, you should disinfect your outerwear.

Winter is coming, the cold current is coming, the goose feather like snow is flying all over the sky, and the whole world is wearing a white coat.

Many customers once again throw this “soul question” to us. “Can your Viral Transport Kits adapt to the cold environment?”

He answer is yes. Let’s follow Cell medical Dr. Li for experimental verification!

Experimental purpose

Verify that the Viral Transport Medium of cell medical (Dongguan) Co., Ltd. has no significant impact on its service performance after low-temperature freezing and thawing.

Experimental scheme

Simulate the process of low-temperature freezing during transportation, place the sampling tube in a low-temperature environment for 24 hours, and then melt at room temperature. The sampling tube products stored normally without freezing and thawing were used as the control. Each group was added with virus mixture, stored at 4 ℃ for 24 hours, and then bathed in water at 56 ℃ for 30 minutes for nucleic acid extraction and nucleic acid detection. Set 2 repetitions for each group.

1. Low temperature icing simulation: set two low temperature gradients and place the sampling tube in two low temperature environments of – 20 ℃ and – 80 ℃ respectively.

2. Mixing of virus solution: We used two different concentrations of virus solutions, representing high and low concentration gradients respectively. The copy numbers of virus solution were 106 copies / ml and 104 copies / ml, respectively. Simulate the actual sampling process, add the virus solution in the volume ratio of 1:10 to the sampling solution, and the virus solution is 100 μ 50. 1ml of sampling solution and add 100 ml to it μ L of oral liquid.

3. After mixing each group, place it in 4 ℃ environment for 24 hours and inactivate it in 56 ℃ water bath for 30 minutes.

4. Extract the nucleic acid of each group of virus, and detect the virus content of each group by RT qPCR. The CT value is used as the basis for result evaluation. The higher the CT value, the higher the detected concentration.

5. The experimental groups are as follows:

Main experimental materials

  •   Sampling solution: virus preservation solution produced by cell medical (Dongguan) Co., Ltd.
  •  virus diluent: the virus isolation serum-free medium of Cell medical was used for gradient dilution.
  •   virus for verification: porcine epidemic diarrhea virus. Its structure and genome size are similar to those of New Coronavirus.
  •   nucleic acid extraction reagent: non cleavage nucleic acid extraction reagent (magnetic bead method).

Nasal Swab Pcr Test

To do a good job of normalization prevention and control, we should accelerate the improvement of detection capacity and carry out nucleic acid and antibody detection on a large scale.

This is not only conducive to accurate prevention and control, maintaining people’s health, but also conducive to the rational flow of personnel and promoting the full resumption of work and production.

Nasopharyngeal swabs are used for nasopharyngeal sampling of respiratory diseases such as COVID-19, influenza, avian influenza and hand foot mouth disease.

For nasopharyngeal Swab Pcr Test, Pay Attention to the Following Points:

1. Please do not take antibiotics a few days before rhinitis swab Pcr Test.

2. Do not rinse your mouth with disinfectant or smear the lesion a few hours before making a nasopharyngeal swab.

3. Don’t eat, smoke or drink a few hours before making a nasopharyngeal swab.

4. If the patient’s turbinate is hypertrophic and the nasal tract is narrow, and the insertion resistance of nasopharyngeal swab is relatively large, we can’t use force rashly. We can try to use the other nasal cavity, or directly use oropharyngeal swab to collect.

5. After sampling, gloves shall be replaced, hands shall be disinfected, and disinfectant shall be sprayed on the place where the patient has touched.

In special times, you should also remember to wear a mask and do a good job in personal hygiene. Once you find a virus, please isolate it to avoid re infection.

Nasal swabs PCR test process

At present, most virus nucleic acid detection kits use fluorescence quantitative PCR to determine whether the sample contains virus nucleic acid by detecting the accumulation of fluorescence signal. So, what steps do nucleic acid detection need to go through? To sum up, there are five steps: sampling, sample retention, preservation, nucleic acid extraction and computer detection.

sampling

Collect human secretions. Wipe the nasal cavity or posterior pharyngeal wall and bilateral tonsils with nasopharyngeal swab or pharyngeal swab

Sample retention

Immerse the swab head into the cell preservation solution, and tighten the tube cover immediately after breaking the tail

preservation

Put the sample tube into a sealed bag, keep it and send it for inspection in time

nucleic acid extraction

Send the sample to the laboratory for nucleic acid extraction

On machine detection

The extract was amplified by fluorescent PCR
