5 Tips on Corona Testing During an Amicron Outbreak

5 نکته در مورد آزمایش کرونا در دوران شیوع گونه امیکرون

With the spread of the Amicron species, the question arises as to whether we should abstain from society for the second year in a row, or whether we can return to a normal life.

Unfortunately, with the prevalence of Amicron species, it has been observed that the transmissibility of this species is 73.2%, while the prevalence of Delta species was 12.6%. Public officials warn that infections of this kind are dangerous – even though vaccines greatly protect against severe infection and death.

But there is a handy tool to help you make that decision: the corona test!

“Experiments provide the insights we need to examine coronas – even when we do not yet know much about this new species,” said Rachel Peach, a public health researcher at Harvard University. For example, we can find out how likely it is that fully vaccinated people become infected.

“Experiments are the only way you can really see what danger you pose to yourself and your community,” said Baron Matma, an assistant professor of epidemiology at Millenn Columbia School of Public Health. “Without it, it is basically impossible to diagnose anything.”

Although these tests still have drawbacks, they are still the most effective way to diagnose the disease. But what should we do about this new species?

  1. How long do we have to wait for symptoms after being exposed to the virus?

Every viral illness has a latency period – from the time a person is exposed to a pathogen until they can be diagnosed by its symptoms. Currently, the Center for Viral Disease Control and Prevention recommends that you wait five to seven days after being exposed to the coronavirus and then get tested. Although there is no general rule yet, scientists think this rule is different for the Amicron species.

Some preliminary data show that it only takes about two to three days for people to become symptomatic after being exposed to an Amicron species. “Experiments seem to be able to detect this new species two days after infection,” says Peach. “Although it is a very bad sign – because it shows the power of the virus – but the important thing is that before the fifth day, the final result will be known and thus the person can cancel his future plans.”

2. Which test should we use and why?

Polymer chain reaction (PCR) tests are the best way to diagnose coronavirus. These tests – which look for genetic signs of the virus – are very sensitive and are unlikely to lead to false-negative results.

Rapid antigen tests, on the other hand, are less reliable. In these tests, fragments of the virus proteins are identified and perform best when the virus is larger in the body. This is why this method only makes a good diagnosis when the person is fully symptomatic.

It should be noted that due to the high spread rate of Amicron species, any home test is not reliable. While it usually takes two to five days for laboratory results to be announced, the increasing number of patients and the overcrowding of laboratories can even disrupt the diagnostic process. Therefore, time should be used optimally in performing PCR test.

This is where antigen tests come into play. These tests can provide doctors with accurate and fast information about the amount of virus in the body within 15 to 30 minutes. Therefore, if a person is fully vaccinated, he or she can quickly detect the virus in the body with the help of this test and try to cure it. The World Health Organization (WHO) says people who are vaccinated are less likely to be infected than those who are not.

However, a rapid negative antigen test can sometimes mean that the virus has not yet grown in your body. But experts warn that given the negative potential, it is necessary to consider the uncertainties of each experiment. Studies have shown that the success rate of each type of virus test is very different – for example, rapid tests can correctly detect up to 85% of former corona species.

According to scientists, the choice of a test depends on the suspect’s risk of coronation. If more confidence is needed, one should go for PCR testing. However, quick tests can only give us a temporary answer.

3. What should be done if the rapid test is negative?

If you have symptoms but the corona test is negative, you should try again. The World Health Organization recommends that you perform two or more rapid tests with at least a 24-hour interval between each. Doctors believe that if the test is still negative, there is probably another type of respiratory infection in the body. But there is no guarantee for that. As the prevalence of colds and flu increases in the cold season, it is best to isolate and mask people as long as there are symptoms.

On the other hand, scientists believe that if the test is negative, the timing of other experiments should be carefully considered because the issue of time is crucial in this case. Because Amicron species have a very high transfer rate – and rapid experiments provide only an instant response – they can be performed up to 12 hours apart.

4. What should we do if the test is positive?

The World Health Organization recommends that those who test positive should stay home for 10 days and inform those with whom they have had contact in the past few days. People who have not been vaccinated should follow this rule, as they are much more likely to get the virus.

However, vaccinated people should be aware that they have a high risk of infection if they see two positive results in their tests. If the second test is negative, the result is not definitive and we have to wait for the PCR test result.

If the PCR does not respond in time, the person should stay home and be isolated for extra reassurance. “It’s true that we do not yet have complete knowledge of the virus, but it is always best to follow health protocols to prevent further spread,” says Pitch.

5. Are we safe against Amicron after receiving the third dose?

The bad news is that it takes time to get the booster vaccine, or the third dose, despite being good for the body. This means that the third dose does not start immediately in the body. Studies show that unlike previous doses, which build up immunity in the body a few days after injection, the third dose begins to produce immunity about a month later.

For this reason, it is not yet clear how safe those receiving the third dose are against emicron. Evidence shows that the immunity created by two doses decreases over time, and the third dose can be a stimulant to increase immunity in the body.

Nevertheless, experts and physicians continue to encourage people to follow health protocols, social distance, wear masks, and wash their hands regularly.
