Several of those infected worked at the city’s Huanan Seafood Wholesale Market, which was shut down on January 1.

On January 7, officials announced they had identified a new virus, according to the WHO. The novel virus was named 2019-nCoV and was identified as belonging to the coronavirus family, which includes SARS and the common cold.
Coronaviruses are common and spread through being in proximity to an infected person and inhaling droplets generated when they cough or sneeze, or touching a surface where these droplets land and then touching one’s face or nose.
