The 2019-nCoV coronavirus has been in the news lately because of the human-to-human transmission and its rapid spread both in China and outside its borders. This virus apparently originated in animals, and it was first identified in seafood and animal markets in Wuhan, China.
As of yesterday, there are 9776 confirmed cases affecting 20 countries already, with the vast majority in China. Johns Hopkins University is maintaining this world cases dashboard, using the most recent data available.
