(ORDO NEWS) — Some studies by scientists have shown that some people may have immunity against covid-19/" 14077 rel="nofollow" target="_blank">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 covid-19/" 14077 rel="nofollow" target="_blank">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 covid-19/" 14077 rel="nofollow" target="_blank">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 covid-19/" 14077 rel="nofollow" target="_blank">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.
