The appeal for launching wide-ranging investigations worldwide is becoming stronger, as more evidence pointing to earlier infections outside China has surfaced recently, said Liang Wannian, the team leader of the Chinese side of the China-World Health Organization joint expert team.
For instance, a skin sample taken from an Italian resident in November 2019 yielded traces of the virus, and traces also were found in human sewage samples collected in Brazil in November 2019. The first infection in Wuhan was reported on Dec 8, 2019.
