President Trump announced in a tweet on Sunday that his administration would increase screening procedures for travelers from countries with a “high risk” of the coronavirus.

“Coronavirus: In addition to screening travelers ‘prior to boarding’ from certain designated high risk countries, or areas within those countries, they will also be screened when they arrive in America. Thank you!,” the president posted.

The tweet came after a Washington State resident died of the virus in the nation’s first confirmed fatal case.

At a press conference in the White House on Saturday, Vice President Mike Pence said the president has directed the State Department to work with Italy and South Korea to coordinate efforts to screen travelers heading to the US.

Screenings have already been in place travelers in Iran and China — two countries hard hit by the virus.

Pence spokeswoman Katie Miller clarified the screening process.

“There is already screening for those coming into the United States for those who have been in China in the last 14 days. This will be expanded to Italy and South Korea,” she said in a statement to CNN. “Additionally, we are currently working on exit screening from South Korea, Italy, and other European Nations as needed.”
