Studies that measure whether a community has developed antibodies against COVID-19 still show average percentages below 10%, so most of humanity is still susceptible to disease, highlighted this Wednesday an expert from the World Health Organization (WHO)
The technical director of the organization for COVID-19, Maria Van Kerkhove, 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 percent of people show evidence of having been infected, so the majority of the world remains susceptible and all kinds of actions still have to be applied to prevent contagion“he said in a question session for Internet users on social networks.
The American expert clarified that in some studies between healthcare workers higher percentages of people with antibodies have been detected, of between 20% and 25%, and in some specific areas, for example in the suburbs of some countries, seroprevalences of over 40% have been obtained.
Van Kerkhove also indicated that there are different results in measurement tests on the resistance of these antibodies, since some investigations show 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 cold-causing coronaviruses, SARS or MERS, antibodies have been shown not to be permanent, so this could also happen with COVID-19“concluded the expert.
