Scientists have found out who can develop “quiet” immunity against COVID-19

Some studies by scientists have shown that some people may have immunity against coronavirus. The so-called “quiet” immunity occurs in citizens who have been in contact with patients.

According to the conclusions of British doctors, the body became resistant to coronavirus in the population group that contracted the virus and transferred it in a mild or asymptomatic form. At the same time, the check shows the presence of traces of COVID-19 in their blood.

Six of the eight residents living with the sick were also infected with the coronavirus, but had almost no symptoms. The developed tests look for specific antibodies in the blood; they do not respond to T cells that fight the virus. This means that the real number of cases can be many times higher: not all people are acutely ill.

Doctors conducted several tests for COVID-19. In the first case, standard tests were used that did not show the presence of the disease in humans. In the second case, T-cell responsive tests were used in supplementation. They showed that in fact people were sick with coronavirus, but in a mild form.

Research has made it clear that the existing method for identifying the infected has flaws: it does not show the real picture and lets out many people who are less susceptible to the disease. Deficiencies in testing lead to underestimation of the impact of the virus. According to experts, approximately 10% of the world’s population is immune. True, this can only be confirmed by testing for the presence of T cells in the blood.

Current statistics say that there are almost 13 million infected and 565 thousand deaths in the world. These numbers will only grow in the coming months.
