WASHINGTON, March 11 (Xinhua) -- The U.S. Department of State issued a travel advisory on Wednesday night, calling on U.S. citizens to reconsider travel abroad due to the global outbreak of COVID-19.

"The Department of State advises U.S. citizens to reconsider travel abroad due to the global impact of COVID-19. Many areas throughout the world are now experiencing COVID-19 outbreaks and taking action that may limit traveler mobility, including quarantines and border restrictions," said the department on its official website.

The United States on Wednesday expanded additional travel restrictions on Europe over coronavirus concerns. President Donald Trump on Wednesday announced a suspension of all travel from Europe except Britain to the United States for the next 30 days in an effort to curb the spread of the coronavirus.

These restrictions will go into effect Friday at midnight and "will be adjusted subject to conditions on the ground," Trump said in his 11-minute address to the nation.

The number of confirmed COVID-19 cases in the United States reached 1,312 as of late night on Wednesday, according to the Center for Systems Science and Engineering at Johns Hopkins University.
