WHO-China Joint Mission on Coronavirus Disease
Investigators from the World Health Organization (WHO) looking into the origins of coronavirus in China have discovered signs the outbreak was much wider in Wuhan in December 2019 than previously thought, and are urgently seeking access to hundreds of thousands of blood samples from the city that China has not so far let them examine.
The slow emergence of more detailed data gathered on the WHO's long-awaited trip into China may add to concerns voiced by other scientists studying the origins of the disease that it may have been spreading in China long before its first official emergence in mid-December.
The virus was circulating widely in Wuhan in December, which is a new finding.
Changes in a virus’s genetic make-up are frequent and usually innocent, occurring over time because the illness strikes between and reproduces amongst folks or animals. Embarek declined to attract conclusions about what the 13 strains may have meant for the illness’s historical past earlier than December.
