The Centers for Disease Control and Prevention has issued new public health requirements for US visitors who have recently been in the Democratic Republic of the Congo or Guinea to address Ebola concerns.
Travellers who have been in the two central African countries in the past 21 days must fly to one of six US airports - JFK, Chicago, Atlanta, Dulles, Newark or Los Angeles, according to the order signed on Tuesday.
The CDC will require airlines to collect and transmit passenger information electronically to the agency for public health follow-up for all passengers who have been in the two countries who are boarding a flight to the United States.
"Timely public health follow-up requires health officials to have immediate access to accurate and complete contact information for travellers as they arrive in the United States," CDC Director Rochelle Walensky said.
Recently, less than 100 people a day have been arriving in the United States who have been in either country.
The CDC said outbreaks are centred in remote areas of the countries and added that "the risk of Ebola to the United States is extremely low".
Three new cases of Ebola have been confirmed in eastern DRC, bringing to 11 the number since authorities declared a resurgence of the deadly virus last month, a health official said on Monday.
The cases represent a flare-up of the 2018-20 epidemic, which killed more than 2200 people before it was declared over last June.
Four people have died and two have recovered among the 11 cases.
In January the Biden Administration, in a move to curb transmission of highly contagious new coronavirus variants, barred most non-US citizens from the United States who have been in South Africa within the previous 14 days, extending restrictions for Brazil and most of Europe since 2020.
