The World Health Organization believes that the coronavirus may have spread from bats. This was announced by a member of the international group of experts of the World Health Organization (WHO) Dr. Peter Daszak, reports The New York Times.
"If you had to say which path (of the spread of the coronavirus, - ed.) you would bet, I believe that the virus appeared in Southeast Asia and South China from bats, and then got to a wild animal farm," he said.
According to him, one of the employees of such farms or their other inhabitants - ferrets, badgers, raccoon dogs and sivetas - could have been infected from COVID-19 bats. Daszak added that during the investigation, WHO experts did not get access to the medical history of some patients, since medical records in China are strictly confidential.
At the same time in the UK, scientists are working to develop a coronavirus vaccine that will be effective against most strains. The Pfizer and AstraZeneca vaccines currently in use are expected to become less effective over time due to frequent mutations in the coronavirus. Already, their effectiveness is lower against strains containing an already mutated adhesive protein, which were found in South Africa and Brazil.
The Ministry of Health of Ukraine is preparing to conduct a seroepidemiological study of the presence of antibodies to Covid-19 in Ukrainians, Chief Sanitary Doctor, Deputy Minister of Health Viktor Lyashko told reporters on Saturday, Interfax-Ukraine reports.
"There will be no mass testing for Covid-19, but we are talking about a sero-epiemiological study that will study blood for the presence of immunoglobulin G and see how many cases of Covid-19 our system does not catch," he said.
According to Lyashko, the study will test about 10,000 people throughout Ukraine, from whom, in accordance with a representative sample, blood will be taken.
The research will be carried out through the Public Health Center.
