Even as virologists absolutely no in on the virus that causes COVID-19, a very standard concern remains unanswered: do those who recover from the illness have resistance?
There is no clear response to this concern, specialists state, even if numerous have actually assumed that contracting the potentially fatal disease provides immunity, at least for a while.
” We do not have the answers to that – it’s an unknown,” Michael Ryan, executive director of the World Health Organization’s Emergencies Program stated in a press conference this week when asked how long a recovered COVID-19 client would have immunity.
” However whether that antibody reaction actually indicates immunity is a different question,” commented Maria Van Kerhove, Technical Lead of the WHO Emergencies Program.
Faced with all these uncertainties, some experts have doubts about the knowledge of pursuing a “herd immunity” technique such that the virus – unable to find brand-new victims – peters out by itself when a majority of the population is immune.
