COVID-19

Can I Get Coronavirus Again

Like any psychologically complex topic, the pandemic story makes people go through the five stages of experience that have become popular thanks to Dr. House: denial, anger, bargaining, depression, acceptance.

Denial (“There is no virus!”) And anger (“Take off your masks, why are you scaring people ?!”) many have already passed. They are followed by the stage of bargaining.

On forums and social networks, users share with each other the details of what they think are unusual SARS that they suffered last winter: with a high unbreakable temperature, weakness, headache, and an obsessive cough – in general, all the symptoms of COVID ‑ 19.

All this inspires people with hope. Like, if I was ill, it means that immunity has already developed and I will not be infected with the coronavirus again.

We Happy Worthy Life explains why you should not be so sure.

Could it be that many have already been ill
Yes, of course. This version is followed not only by regulars of social networks, but also by some serious scientific and state structures. For example, representatives from Oxford University.

Professor of Theoretical Epidemiology Sunetra Gupta (Sunetra Gupta), along with colleagues in late March put forward a version Fundamental principles of epidemic spread highlight the immediate need for large ‑ scale serological surveys to assess the stage of the SARS ‑ CoV ‑ 2 epidemic that coronavirus in the winter infected up to half of the UK population. But supposedly the majority of citizens were ill asymptomatically or easily, like a normal SARS, and now “collective immunity” is already present in the country. This means that strict quarantine measures that kill the economy can be weakened.

True, the Oxford study has not yet passed a scientific review. In addition, his results were disputed by other scientists. However, this bold scientific work has borne fruit.

The Guardian edition reports that the UK government has already purchased 3.5 million test kits. The goal is to conduct a large-scale serological study of the country’s population to find out how many people already have immunity to COVID ‑ 19.

Other states are also beginning to move along the same path. Germany plans make tests for 100 thousand people to try to find antibodies to coronavirus infection in their blood. According to the results of testing, people who are found to be immune to COVID ‑ 19 may begin to issue unique certificates confirming their safety for society. Such people will be able to quarantine and return to work earlier than others.

USA also hopes create test systems that will identify citizens with immunity to coronavirus.

The theory really looks beautiful. But there’s a problem.

Can I get coronavirus again

Not excluded. Doctors still do not know how strong and complete the immunity to COVID-19 is. At their disposal is only indirect data. And that is very controversial.

So, a small study of another coronavirus, also causing a cold, showed: People may become infected again after a year, but their symptoms will be weaker.

Scientists have studied and the closest relative of the Wuhan coronavirus is SARS. It turned out that IgG immunoglobulins – the very antibodies associated with stable immunity – appeared in the blood of patients after 21-30 days after the first symptoms and persisted for at least 2 years.

A recent study was conducted on macaques. Chinese scientists infected SARS ‑ CoV ‑ 2 animals, and then, when they were ill and fully recovered, they introduced the same virus again. This time, the monkeys had almost no symptoms, and antibodies to coronavirus were found in their blood. This study did not pass a scientific review, but it looks promising and optimistic.

Chinese edition of South China Morning Post reports that up to 10% of patients from Wuhan who have had coronavirus later seem to have contracted it again. Tests for COVID ‑ 19, which were negative during recovery, then, after a week and a half, again showed a positive result.

The facts of reinfection still require rechecking: it may well turn out that some of the tests were simply corrupted and gave a false result. However, there is another explanation.

Even if antibodies appear in your blood, this does not necessarily mean thatyou have developed immunity to the disease. It must be assessed whether the antibodies provide a sufficient level of protection. There is no exact information on this subject today.
Elitza Theel, MD, assistant professor at the Department of Laboratory Medicine and Pathology at Mayo Clinic

In general, it is far from a fact that antibodies to SARS ‑ CoV ‑ 2 coronavirus appear at the same time and are as stable as antibodies to SARS. The immunity to COVID ‑ 19 may be longer. Or, on the contrary, it may turn out to be short-lived – such that you easily catch a dangerous coronavirus infection again, having been ill with it just a couple of weeks ago.

It remains only to repeat the theses that have been voiced for almost three consecutive months experts at the US Centers for Disease Control and Prevention (CDC): we still don’t know much about SARS ‑ CoV ‑ 2. Data is updated and changed literally every day. Therefore, it is important to be careful and observe the self-isolation mode.
