China faces calls to release everything it knows about the origin of COVID-19 after an analysis provided a new clue in how the virus eventually reached humans.
WHO, advisers urge China to release all COVID data
World Health Organisation advisers have urged China to release all information related to the origin of the COVID-19 pandemic after new findings were briefly shared on an international database used to track pathogens.
New sequences of the SARS-CoV-2 virus as well as additional genomic data based on samples taken from a live animal market in Wuhan, China, in 2020 were briefly uploaded to the GISAID database by Chinese scientists earlier this year, allowing them to be viewed by researchers in other countries, according to the WHO’s Scientific Advisory Group for the Origins of Novel Pathogens (SAGO).
The sequences suggest that raccoon dogs were present in the market and might have also been infected by the coronavirus, providing a new clue in the chain of transmission that eventually reached humans.
Access to the information was subsequently restricted “apparently to allow further data updates” by the Chinese Centre for Disease Control and Prevention (CDC).
