Who can develop a “quiet” immunity against Covid-19
(ORDO NEWS) — Some studies by scientists have shown that some people may have immunity against coronavirus. The so-called “quiet” immunity occurs in citizens who have contacted patients.
According to the findings of British doctors, the body became resistant to coronavirus in the population that contracted the virus and transferred it in a mild or asymptomatic form. In this case, the check shows the presence of traces of Covid-19 in their blood.
Six out of eight residents living with the sick were also infected with 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 actual number of patients can be many times greater: not all people acutely tolerate the disease.
Doctors conducted several tests on the Covid-19. In the first case, standard tests were used that did not show the presence of the disease in people. In the second case, T-cell responsive tests were used as additives. They showed that in fact people suffered from coronavirus, but in a mild form.
Studies have made it clear that the existing method for identifying infected people has flaws: it does not show the real picture and misses a lot of people who are less susceptible to the disease. Test flaws lead to an underestimation of the effect of the virus. According to experts, approximately 10% of the world’s population are 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 dead in the world. In the coming months, these numbers will only grow.
