The specialists from WHO finished work in China after six month of the investigation mission. The purpose of these researches will serve as the basis for works into the origins of the disease, claimed Director-General of WHO Ghebreyesus .
Their aim is going to check the origin source of infection during first cases of the virus infection. The evidence and hypotheses that emerge from this research will be the basics for further research.
Michael Ryan, Director of the WHO Health Emergencies Program, has noted that the team had completed its work, but had not yet returned to Geneva. Hence to this the main task of the specialists was to continue the work that had already been done to understand the origin of the virus.
Ryan also noted that areas where cases of virus infection are first detected are not necessarily areas where animal-to-person transmission of the virus has occurred. Researchers need to understand whether the barrier in transmission of the virus between animals and humans has been overcome in areas other than Wuhan, as well as more clearly determine the possible sources and carriers of infection among animals.
The coronavirus began to spread in the Chinese city of Wuhan (Hubei province). Most scientists believe that the SARS-CoV-2 virus that causes COVID-19 is of zoonotic origin. It is assumed that it could be transmitted to humans from bats.
Earlier, WHO approved a resolution calling for a systematic analysis of how the international community has responded to the COVID-19 pandemic. However, there was no talk of investigating the circumstances of the origin of the virus at that time.
