Wild animals sold on the southwestern side of the Huanan Seafood Wholesale Market in Wuhan were the most likely source of the COVID-19 outbreak, a team of 18 international scientists claim. While there's still no 'smoking gun', it seems there is a mountain of circumstantial evidence that would be very statistically unlikely to exist without the Wuhan markets at the epicenter of the outbreak. [...] When comparing the infected group to the general population of the same age living in Wuhan, the researchers found that infected people lived significantly closer to the Wuhan market than one would expect from random chance alone. [...] If the markets were the source of infection, one might expect people living close by to be at greater risk than those living further out in the city. Those living far away would be more likely to catch COVID-19 only if they happened to visit the markets or worked there, and that's exactly what the data suggest.
