Donald Trump has issued a proclamation suspending entry into the United States for any individual who has been in Brazil within 14 days, citing concerns over Brazil’s rapidly worsening coronavirus crisis.

The proclamation reads in part, “I have determined that it is in the interests of the United States to take action to restrict and suspend the entry into the United States, as immigrants or nonimmigrants, of all aliens who were physically present within the Federative Republic of Brazil during the 14-day period preceding their entry or attempted entry into the United States.”

The president’s proclamation aims to limit the spread of coronavirus coming into the United States from Brazil, the country with the second-most cases worldwide, according to Johns Hopkins University. As of May 24, the country had reported more than 347,000 cases of COVID-19 and at least 22,000 deaths.

Green card holders and other categories of foreign nationals, including family members of U.S. citizens and permanent residents are exempt from the temporary travel restriction. 

“Today’s action will help ensure foreign nationals who have been in Brazil do not become a source of additional infections in our country,” White House Press Secretary Kayleigh McEnany said in a statement.

The new restrictions take effect on May 28, but according to McEnany, they only apply to travel, not “the flow of commerce between the United States and Brazil.”

Coronavirus has not peaked yet in Sao Paulo, Brazil’s largest and worst-infected city, but the health care system is already beginning to break down.
