The technical director of the WHO for the organization of the covid-19 study, Maria Van Kerkhove, clarified this Wednesday, quoted by the Efe news agency, that there are hundreds of seroprevalence studies with very disparate results and that, therefore, it is It is difficult to reach categorical conclusions, but in principle they show that more than 90% of individuals remain free of antibodies ”.
“Looking at these cases together, it seems that less than 10% of people show signs of being infected.

The American specialist explained that in some studies with health workers, higher percentages of people with antibodies were detected, between 20% and 25%, and in some specific areas, such as in the suburbs of some countries, more seroprevalences were obtained. high. to 40%.
Van Kerkhove also indicated that there are different results in tests to measure the resistance of these antibodies, since some research shows that their effectiveness against the virus decreases after a certain time, while others indicate that it does not vary.
“In any case, with other coronaviruses that cause colds, SARS or MERS, it is proven that the antibodies are not permanent, so this can also happen with covid-19,” the expert concluded.
