The Ongoing Mystery of Covid’s Origin

NY Times We still don’t know how the pandemic started. Here’s what we do know — and why it matters. Where did it come from? More than three years into the pandemic and untold millions of people dead, that question about the Covid-19 coronavirus remains controversial and fraught, with facts sparkling amid a tangle of analyses and hypotheticals like Christmas lights strung on a dark, thorny tree. One school of thought holds that the virus, known to science as SARS-CoV-2, spilled into humans from a nonhuman animal, probably in the Huanan Seafood Wholesale Market, a messy emporium in Wuhan, China, brimming with fish, meats and wildlife on sale as food. Another school argues that the virus was laboratory-engineered to infect humans and cause them harm — a bioweapon — and was possibly devised in a “shadow project” sponsored by the People’s Liberation Army of China. A third school, more moderate than the second but also implicating laboratory work, suggests that the virus got into its first human victim by way of an accident at the Wuhan Institute of Virology (W.I.V.), a research complex on the eastern side of the city, maybe after well-meaning but reckless genetic manipulation that made it more dangerous to people.
