Wuhan not necessarily where coronavirus crossed from animals into humans: WHO expert
GENEVA, Aug. 3 (Xinhua) -- Although the first clusters of atypical pneumonia were reported in Wuhan, China, it doesn't necessarily mean that is where the COVID-19 disease crossed from animals into humans, a senior World Health Organization (WHO) expert said on Monday.
Dr. Michael Ryan, executive director of the WHO Health Emergencies Program, said at a routine COVID-19 briefing on Monday that a much more "extensive retrospective epidemiological study" should be taken to fully understand the links between the cases.
