Covid-19 Pandemic: 2020 Coronavirus outbreak
The earliest reported symptoms
Of the first 41 confirmed cases of 2019-nCoV infection, two-thirds were found to have a link with the Huanan Seafood Wholesale Market, which also sold live animals. The earliest reported symptoms occurred on 1 December 2019, in a person who did not have any exposure to the market or to the remaining 40 affected people. As the number of cases has increased, the significance of the market lessened.
