U.S. nationals and lawful permanent residents who were in the Democratic Republic of Congo (DRC), Uganda, or South Sudan within 21 days are permitted to enter the United States, but will be subject to enhanced public health screening. The CDC has suspended entry to the United States by foreign nationals who were in these countries within 21 days before arrival.

The CDC stated, "To date, no suspected, probable, or confirmed cases of Ebola have been reported in the United States, and the risk of Ebola domestically is low. However, public health entry screening is part of a layered approach that, when used with other public health measures already in place to detect symptomatic arriving travelers, can slow and reduce the spread of disease into the United States."
