Another case of coronavirus has been reported in Santa Clara County, officials from the the county's public health department said Sunday.

On Friday, Santa Clara County reported the Bay Area's first case of the disease, but officials believe the two cases are unrelated.

The second patient is a woman who traveled to Wuhan, China and arrived in the Bay Area on January 23 to visit family. The first patient was a male who traveled to Wuhan who returned to the Bay Area on January 24.

Both patients have been "self-isolated" since falling ill, and only left their homes to seek medical attention.

So far, 10,000 people have been infected globally and more than 200 have died. All of the deaths have occurred in China, where the disease originated.

Americans returning from Hubei province, the center of the outbreak, will be required to undergo 14 days of quarantine. Others returning from elsewhere in China will be allowed to self-monitor their condition for a similar period. The U.S. will also begin funneling all flights to the U.S. from China to seven major airports where passengers can be screened for the illness.
