Covid Origins: Market or Lab Leak?

Five years ago this month, the first patients started arriving in hospitals in Wuhan, China, with a mysterious kind of pneumonia.Covid was described as a “public health emergency of international concern” by the World Health Organization in January 2020.

But the nearby Wuhan Institute of Virology had been studying other viruses in the coronavirus family for the past decade, raising suspicions this was the real source. Some people have even speculated that this lab deliberately engineered the Covid virus. The last claim has few serious advocates. Virologists have been poring over the genetic sequence of this virus since January 2020; if it weren’t a completely natural virus, it would be obvious. But Covid could have leaked from the Wuhan lab accidentally, for instance, if a worker got infected and passed it on. They might not have even noticed.
