BEIJING — Genetic material collected at a Chinese market near where the first human cases of COVID-19 were identified show raccoon dog DNA comingled with the virus, adding evidence to the theory that the virus originated from animals, not from a lab, international experts say.
Tedros criticized China for not sharing the genetic information earlier, telling a press briefing that “this data could have and should have been shared three years ago.” The data show that some of the COVID-positive samples collected from a stall known to be involved in the wildlife trade also contained raccoon dog genes, indicating the animals may have been infected by the virus, according to the scientists. Their analysis was first reported in The Atlantic.
WHO's COVID-19 technical lead, Maria Van Kerkhove, cautioned that the analysis did not find the virus within any animal, nor did it find any hard evidence that any animals infected humans. It took virus experts more than a dozen years to pinpoint the animal origin of SARS, a related virus. Goldstein said his group presented its findings this week to a WHO advisory panel investigating COVID-19’s origins.
