Chinese health officials in Wuhan report 136 new cases of a newly confirmed coronavirus in the past three days, bringing the total number of cases of the potentially deadly virus to nearly 200.
Most of the confirmed cases are mild, but at least three deaths are reported, according to the Wuhan Municipal Health Commission. The WHO reported 139 new confirmed cases, citing China as a source.
On Friday, U.S. health officials began screening passengers arriving from Wuhan at three U.S. airports: San Francisco, Los Angeles, and New York.
The virus is believed to have started in Wuhan. It belongs to the same family of coronaviruses that includes the common cold as well as severe acute respiratory syndrome (SARS). SARS killed nearly 800 people globally during an outbreak 17 years ago. It also started in China.
