Antibodies have been shown not to be permanent with other viruses
Studies that measure whether a community has developed antibodies against covid-19 they still show average percentages below 10%, so that most of humanity is still susceptible to the disease, an expert from the World Health Organization (WHO) highlighted today.
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 105 of the people show evidence of having been infected, so most of the world it is still susceptible and all kinds of actions 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 among health workers, higher percentages of people with antibodies have been detected, among the 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, as some research shows that its effectiveness against the virus is reduced after a certain time, while others indicate that it does not vary.
“Anyway, with other cold-causing coronaviruses, SARS or MERS, it has been proven that antibodies are not permanent, so this could also happen with covid-19 “, concluded the expert.
