Tokyo:A Japanese expert from the World Health Organization (WHO), who visited Wuhan as part of the investigative team to look into the origins of COVID-19, has voiced scepticism on China's stance that the virus had originally entered the country from abroad through a cold chain.
The possibility is not so high that the virus entered Wuhan on frozen-food packages as China claims, said Ken Maeda, a veterinary microbiologist at Japan's National Institute of Infectious Diseases.
He further said that there was a "perception gap" between the WHO group and its Chinese counterparts.

"We still have a lot of things we want to know and there remain many challenges," the WHO expert added.
Weeks after a team of WHO experts launched a probe into the origin of the COVID-19 in Wuhan, the global health body had said that there is no evidence of coronavirus circulation in any animal species in China.
During a press conference, Peter Ben Embarek, the head of the WHO mission in Wuhan, stated four hypotheses on how the virus spread but reiterated that "laboratory incident hypothesis is extremely unlikely to explain the introduction of the virus into the human population".
