Passengers wear face masks in a subway station in Beijing, one of several cities in China that have reported cases of a new coronavirus.

It’s hard to keep up with the outbreak of the new coronavirus that emerged in Wuhan last month, but one thing seems increasingly clear: The virus isn’t going away anytime soon. The U.S. Centers for Disease Control and Prevention (CDC) just reported the first case in the United States, a patient who returned from Wuhan on 15 January and sought treatment in Washington after developing symptoms. Taiwan also confirmed its first infection today, and a boy in the Philippines reportedly tested positive for the virus. (Thailand, Japan, and South Korea have all previously reported cases.) The total number of confirmed cases again shot up today, to more than 300, including six deaths.
