Nearly a 140 Americans who've completed a quarantine period here at the Travis Air Force Base are finally free to go home.

They are all former passengers of the Diamond Princess cruise ship, which docked in Yokohama, Japan last month but was quarantined after passengers tested positive for the novel coronavirus. Confined on board, the infection rate exploded—going to from 10 to more than 700.

Around a dozen will remain here on base for various reasons. The Centers for Disease Prevention and Control says those who were allowed to leave today had to pass at LEAST two negative tests to make sure there's no risk of spreading infection.

Several patients who tested positive for the virus have been treated in isolation wards in local hospitals.

The entire process at Travis Air Force Base aimed to ensure that repatriated passengers wouldn't bring this infection into their communities.

The bigger concern now is the new infections elsewhere in California and the rest of the country. 

The Santa Clara County's Public health department announced on Sunday, five new cases of coronavirus in Northern California, including two health workers who were likely infected while exposed to an infected patient.

Officials continue to emphasize that the overall risk level to the general public still remains low. 

Though, we are noticing that many locals are stocking up basic supplies, including hand sanitizers, toilet papers and in some cases even food items.

California's hospitals are expected to receive more testing kits from the CDC, in an effort to step up their ability to respond to this evolving situation.
