US intelligence agencies have failed to reach a conclusion on whether Covid-19 first spread to humans through animals or because of an accident at China’s Wuhan Institute of Virology, as the debate over the pandemic’s origins continues to rage.
Joe Biden, the US president, asked his spy chiefs three months ago to reassess how the virus first emerged and whether Chinese scientists were to blame.
A full report on the agencies’ findings was presented to Biden earlier this week. A one-page summary of that report published on Friday said the US intelligence community remains split on the core question, with one agency believing it emerged through a lab leak, four believing it came from animals and three others unable to decide.
