President Biden on Thursday signed an executive order to back up Centers for Disease Control and Prevention (CDC) guidelines recommending that international travelers quarantine for seven days after arriving in the United States.

Biden’s executive order says travelers must comply with CDC orders that require a negative COVID-19 test to get into the country as well as a quarantine period upon arrival to the states. .

“The Secretary of State, in consultation with the Secretary of HHS, the Secretary of Transportation, the Secretary of Homeland Security, and the Director of CDC, shall immediately commence diplomatic outreach to the governments of Canada and Mexico regarding public health protocols for land ports of entry,” the order states.
