Covid infection. As per Kerkhove, the Huanan market in China's Wuhan district indeed played a "very important role" in this pandemic, and she would urge further studies continue to be needed to trace back animals sold there prior to the first detected cases.8/ Several studies since Mar’21 have identified animal species that were sold at Wuhan markets that are susceptible to #SARSCoV2 infection.
The Huanan market indeed played a very important role in this pandemic, but I would urge further studies continue to be needed… Kerkhove said, however, there's still much uncertainty and that more research in this area should be welcomed. "We need more serology in specific populations and to ensure we further study earlier suspected cases into November 2019 and possibly earlier," she added.
She said for SARS-CoV-2 more studies are needed to better understand the exposures of the earliest known and even earlier potential cases. "Data from multiple studies are needed — it's like detective work (and I mean this without a police reference)," she quipped.
Notably, scientists have released two latest studies that give some clues about how the Covid-19 virus had first emerged. These studies, which are still in preprints, are yet to be peer-reviewed.
