Studies that measure whether a community has developed antibodies against COVID-19 still show average percentages below 10%, so lmost of humanity remains susceptible to disease, An expert from the World Health Organization (WHO) highlighted this Wednesday

The technical director of the organization for COVID-19, Maria Van Kerkhove, has clarified that there are hundreds of these seroprevalence studies with very different results, so it is difficult to reach categorical conclusions, but in principle they show that more than 90% of the subjects remain without antibodies.

“Looking at them collectively, it appears that less than 10% of people show evidence of being infected, so most of the world remains susceptible and they still have to apply all kinds of actions to prevent contagion“, has indicated in a session of questions of the internauts in the social networks.

The American expert has clarified that in some studies among health workers, higher percentages of people with antibodies, between 20% and 25%, and in some specific areas, for example in the suburbs of some countries, it has been possible to obtain seroprevalences greater than 40%.

Van Kerkhove has also indicated that there are different results in measurement tests on the resistance of these antibodies, as some research shows that its effectiveness against the virus is reduced 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 has been proven that the antibodies are not permanent, so this could also occur with COVID-19,” the expert concluded.
