And yet … Is it possible to re-contract the coronavirus?

The quarantine week is in full swing, we regularly learn about new cases from the news reports, there are more and more questions about covid-19, the answers to them, if they appear, then also change over time. One of the questions is still relevant. Is it true that even after recovery, the likelihood of contracting the virus remains?

The quarantine week is in full swing, we regularly learn about new cases from the news reports, and there are more and more questions about covid-19. Is it true that even if you have already overcome this disease, is there a chance of contracting it again? We understand the issue of reinfection with coronavirus in our material.

According to official figures, the number of cases of infection with the new coronavirus is over 800,000, the pathogen continues to spread throughout the world. However, the latest data also shows that more than 172,000 people have already recovered. It is known that people who have had coronavirus produce antibodies in their bodies, but it remains unclear how long this protection will last. As it turned out, the fact of recovery does not guarantee that a person will not be at risk of contracting the disease in the future.

How it all started

At the end of February, there were reports that some patients in China had re-contracted the coronavirus after they were discharged from the hospital. More than 100 people have received a second positive test for coronavirus. This news raised doubts about the ability to develop immunity to the coronavirus. This state of affairs would mean that until we have an effective vaccine, we can all experience repeated cycles of infection.

Why could this have happened?

An overloaded healthcare system could be the reason for the re-detection of infection in China. Hospitals were unprepared for such an influx of patients and doctors were forced to discharge people who may not have fully recovered in order to make room for newly infected patients. Accordingly, people who tested positive for coronavirus again may not have fully recovered from the disease.

Additionally, in February, Wang Chen, director of the state-run Chinese Academy of Medical Sciences, calculated that nucleic acid tests used in China were accurate in detecting positive cases of coronavirus in only 30-50% of cases. This means that the margin of error in the first tests was relatively high. If the patient's well-being improved, the test could show an incorrect result and the patient was discharged. Then the disease progressed again.

What Science Says

The isolated results from a number of small animal experiments are encouraging. A team of researchers from the Chinese Academy of Medical Sciences in Beijing exposed four macaques to the virus. After a week, all four were experiencing some symptoms of SARS and had a high viral load. After 28 days, the macaques finally recovered, and scientists confirmed the presence of antibodies to the virus in their bloodstream. Then the researchers tried to re-infect two of them, but nothing worked - the animals did not get sick. This suggests that they already had a protective immunity to the virus and it is impossible to become infected with the coronavirus twice in a short period of time.

Output

Based on early research, it can be said that the body is capable of developing immunity to the coronavirus. But that doesn't necessarily mean long-term immunity. Some other viruses in the coronavirus family that cause common colds tend to induce immunity, but it lasts for about three months. Therefore, re-infection with coronavirus is possible after the effect of immunity to this disease has ended. Cases of re-diagnosis of the disease in discharged patients could also be associated with the inaccuracy of the test itself and the slow clearance of the virus from the body.
