While confirmed cases of the virus have continued to increase in the country, the Director General of the World Health Organisation, Tedros Ghebreyesus, on Tuesday during a virtual briefing in Geneva, said health experts from the agency will travel to China this weekend to work with their Chinese counterparts to prepare scientific plans for identifying the zoonotic source of COVID-19.
Mr Ghebreyesus said the experts will develop the scope and terms of reference for a WHO-led international mission.
"Identifying the origin of emerging viral disease has proven complex in past epidemics in different countries. A well planned series of scientific researches will advance the understanding of animal reservoirs and the route of COVID-19 transmission to humans.
"This process is an evolving endeavour which may lead to further international scientific research and collaboration globally," he said.
