The US has at least 11 confirmed cases of coronavirus and the virus has killed more than 420 people in China as of Feb. 3, according to an article on the CNN website.
The Centers for Disease Control and Prevention (CDC) is trying to expedite the "emergency use authorization" for tests so more parts of the United States can test for and diagnose the coronavirus.
The CDC in Atlanta is the only place in the United States that can confirm whether a patient has the virus, which has infected more than 17,000 in China.
Around the world, more than 170 confirmed cases have been reported in more than 20 countries.
