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

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.

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.

How much do you know about COVID-19 antigen detection technology?

In late spring and summer of 2020, the COVID-19 epidemic was initially resurgent beyond all expectations, and unexpectedly came back with a strong attitude.

“COVID-19” On August 26, 2020, in order to control the spread of the epidemic.Abbottswab.

In addition, the federal government will spend $760 million to buy 150 million copies of reagents and transport them to nursing homes and schools in about a month.

Antigen detection.

By the end of October 2020, with more similar tests under way and waiting for emergency approval.

Three more antigen test kits have obtained the emergency use authorization (EUA) of the US Food and Drug Administration (US FDA), and the total number has reached 7.

In addition, although the World Health Organization was unwilling to do so at first.

It also approved the use of two antigen detection kits following the emergency authorization of the U.S. Food and Drug Administration in September and October 2020.

In the invention and transformation caused by covid-19 pandemic, detection technology has become a hot spot of biotechnology and engineering innovation.

In addition, more extensive measures such as wearing masks, maintaining social distance, isolating and tracking contacts.

And faster and cheaper screening tests provided by Cell medical provide hope for people’s urgent need to combat this infectious disease and make progress.

Many places in the world that seemed to have controlled the epidemic in the early stage broke out again.

Which shocked public health experts and called on everyone to carry out rapid and frequent testing.

Covid 19 self test rapid antigen test.

According to a report recently released by the Rockefeller Foundation.

If only to meet the testing needs of primary and secondary schools and nursing homes.

The United States should complete 200 million rapid tests per month by January 2021.

Although people tend to detect with higher accuracy, antigen detection with accuracy of only 70% .

People can also find infected persons omitted from previous tests through frequent detection. And provide sufficient accuracy for continuous screening.

According to Mara g. Aspinall, a practical professor and medical diagnostic expert at Arizona State University (ASU) in Tempe.

The co-author of the report, the number of tests required to screen the entire U.S. population may be twice that required by schools.

“Now it’s time,” Aspinall said. “We have an agreement and testing reagents. I hope the community can reduce the spread of the virus and control the epidemic again.”

All about the Nasal Swab

Nasal Swab:nasopharyngeal np swab.

The specimens collected from nucleic acid samples are mainly pharyngeal swabs, which are divided into “nasopharyngeal swabs” and “oropharyngeal swabs“.

Nasopharynx swab and oropharyngeal swab only have different sampling paths. Oropharyngeal swab is to collect oropharyngeal specimens by entering the sampling swab through the mouth, and nasopharyngeal swab is to collect nasopharyngeal specimens through the nose.

How to do a nasopharyngeal swab?

A man was doing a nasopharyngeal swab sample

A man was doing a nasopharyngeal swab sample

Nasopharyngeal swab sampling method.

Hold a swab close to the nostril to enter, and slowly go deep along the bottom of the lower nasal tract.

Since the nasal tract is curved, do not use too much force to avoid trauma and bleeding.

When the top of the swab reaches the posterior wall of the nasopharyngeal cavity, rotate it gently for one week (stay for a moment in case of reflex cough), then slowly take out the swab and immerse the swab head into a tube containing 2 ~ 3ml virus preservation solution.

About Nasal swab sample collection.

How to take a swab sample?

Ask the patient to take off the mask and blow his nose with a paper towel to remove excess secretions from the nasal cavity. Remove the swab from the package.

Tilt the patient’s head back slightly to make the nasal passage easier to pass through. Ask the patient to close their eyes to reduce the mild discomfort of the operation.

Gently insert the swab over the bottom of the nasal canal along the nasal septum until the nasopharynx stops when resistance is felt.

Insert the cotton swab parallel to the upper jaw into the nostril.

If you feel resistance when passing, step back and try to reinsert it at another angle to bring it closer to the bottom of the nasal canal.

The depth of the swab should be equal to the distance from the nostril to the opening outside the ear.

CDC recommends placing the swab for a few seconds to absorb enough secretions, and then slowly removing it while rotating the swab.

Some organizations may also recommend rotating the cotton swab several times before taking it out.

After removal, ask the patient to put on the mask again.

Specimen processing

Open the virus transport medium and insert the swab into the collection tube.

Break the swab at the groove and discard the remaining part. Seal the labeled collection tube and place it in the biohazard garbage bag.

According to convention, you can return the sample to its original packaging for disposal.

Follow CDC instructions for direct treatment of swab specimens or place swabs in medium with or without refrigeration.

Quick covid test

Quick covid test |How does covid testing work?

Posted on by

A new covid test at home has been authorized by the U.S. Food and Drug Administration (FDA) for emergency use (EUA).

Here’s what you need to know about testing at home.

How can I get quick covid test?

Cell medical’s covid test at home now has a prescription, which means Americans can get one from their health care provider.

If doctors suspect that their patient is infected with covid – 19 within the first six days of symptom onset, they can prescribe a rapid test.

Quick covid test Rapid Antigen Test Kit Nasal Saliva Test at home

How much does it cost?

Please contact us for more details.

How does testing work?

Rapid Antigen Test is a lateral flow test, a portable covid test that usually returns results faster than the widely used laboratory based PCR test.

It works by detecting nasal swab samples and provides positive or negative results within 10 minutes. The results appear on test strips exposed to nasal swab samples.

The FDA said flocked swab can be collected from people aged 8 and over, but if the tested children are less than 14 years old, it should be collected by adults.

How accurate is the test?

Cell medical claimed that the time when the positive results of the test matched the PCR test was 84.8%, and the negative results matched the PCR test were 99.1%.

FDA said that the negative test results of covid test do not necessarily exclude the possibility of covid – 19 infection.

“and should not be used as the only basis for treatment or patient management decisions, including infection control decisions.

“People who are negative and continue to experience COVID 19, have a fever, cough and / or shortness of breath, may still have SARS – CoV – 2 infection. Follow up care should be sought from doctors or medical staff. ”

Not all side flow tests require the use of prescriptions. On December 15, the FDA issued the EUA for the first outside counter flow covid test at home.

The covid – 19 family test also uses nasal swab samples to detect covid infection and works with people aged 2 years and older.

The FDA said that in the population with covid symptoms, the ellume test correctly identified 96% of positive samples and 100% of negative samples. In the population without symptoms, it collected 91% of positive samples and 96% of negative samples.

Similarly, the FDA said that the negative results of the test do not necessarily exclude the possibility of covid infection.

Broader prospects

According to CDC data, as of Monday, the United States had reported 47.5million cases of covid and 778,316 deaths.

The data also showed that 432 million people were vaccinated on Monday.

Whether nucleic acid detection or virus detection.

Universal Transport Medium (UTM) and NP Flocked Flexible Swab sampling swab play a great role.

NP Flocked Flexible Swab : Used to collect virus samples.Nasopharyngeal sample.

While virus preservation solution plays the role of preserving these virus samples.

which not only ensures the integrity of nucleic acid virus, but also facilitates the later detection accuracy.

How many Universal Transport Medium are there? What are the functions and differences?

At present, there are two kinds of Universal Transport Medium on the market, namely inactivated virus preservation solution and non inactivated virus preservation solution.

Inactivated Virus Transport Medium :Use to lyse and inactivate the virus.

It can protect the tester from the second infection of the virus.

Stored at room temperature for a relatively long time, saving the cost of virus samples and transportation.

The purpose of non inactivated virus preservation solution is to retain the protein shell of the virus and the nucleic acid DNA or RNA of the virus, so as to ensure the integrity of the nucleic acid of the virus sample in the process of submission for inspection.

Although there will be a certain infectious risk in case of misoperation, this preservation solution maintains the originality of the virus sample to the greatest extent and is a cultured virus transport medium.

Noted:long-term storage requires strict low-temperature storage after sampling.

Relatively speaking, the non inactivated virus preservation solution has higher requirements for the laboratory, higher sensitivity and more applications. But it is relatively easy to be infected.

As long as there are no problems in sampling and detection operations, there will be no risk problems.

How to select inactivated and non inactivated virus preservation solutions cannot be generalized, We should choose according to different needs, and the price determines the quality.

Don’t be greedy for small things and lose big ones.
