WASHINGTON (REUTERS) - The United States said Tuesday (Feb 11) it had authorised consulate staff to leave Hong Kong as concerns spread over the coronavirus that originated in mainland China.

Non-essential staff and their family members will be allowed, but not required, to leave the metropolis "out of an abundance of caution related to uncertainties" on the coronavirus, a State Department spokesperson said.

The US consulate in Hong Kong will remain open, the State Department said.
