At least 1 American has tested positive for Ebola: CDC

The Centers for Disease Control and Prevention confirmed on Monday that at least one American working in the Democratic Republic of the Congo has tested positive for Ebola.

Dr. Satish K. Pillai, incident manager for the CDC's Ebola response, told reporters that the individual developed symptoms over the weekend and tested positive late Sunday.

Pillai added that the patient is being moved to Germany for care and stressed that the risk to the U.S. general public remains low.

The CDC said earlier Monday that it is preparing to restrict entry for travelers arriving from parts of central Africa where an Ebola outbreak has been declared.

Non-U.S. passport holders will face entry restrictions if they have been in the Democratic Republic of the Congo, Uganda or South Sudan in the previous 21 days.

The move is being carried out under Title 42 of the Public Health Services Act, which allows the CDC director to suspend entry of individuals into the U.S. to protect public health. 

The order will be in effect for 30 days and does not apply to U.S. citizens or lawful permanent residents.

The CDC said it is also coordinating with airlines, international partners and port-of-entry officials to identify and manage travelers with possible Ebola exposure as well as enhancing measures like contact tracing, laboratory testing capacity and hospital readiness nationwide.

On Sunday, the CDC said in a statement that a "small number of Americans" are directly affected by an Ebola outbreak occurring in the Democratic Republic of Congo.

"The CDC is working with other U.S. agencies to coordinate the safe withdrawal of the Americans," the CDC said. The agency did not confirm the number of people affected, the type of exposure or whether any individuals had experienced symptoms.

"We don't discuss or comment on individual dispositions," Pillai said Sunday. "It is a highly dynamic situation, and at this point, what I would say is, we continue to assess, we will continue to keep you posted as we learn more."

On Saturday, the World Health Organization said in a statement that the Ebola outbreak in the DRC and Uganda constituted a "public health emergency of international concern."

As of Sunday, there were 10 confirmed Ebola cases and 336 suspected cases in the DRC. There had been 88 suspected deaths in the DRC, as well as two confirmed cases and one confirmed death in Uganda from people who had traveled to the DRC.

The CDC said the risk to the American public remains low. Ebola virus spreads through direct contact with the bodily fluids of an infected person and does not spread through casual contact or air.

"CDC has extensive experience and expertise in responding to Ebola outbreaks," CDC acting director Dr. Jay Bhattacharya said on a call with reporters on Friday. "It is a large outbreak, and we were just informed yesterday about it."

He added, "We're absolutely committed to making sure that they can get resources as they need. We have helped with other Ebola outbreaks in the past ... we have lots of hard-earned lessons. The key thing here is to know that we are absolutely involved."

This is the DRC's 17th outbreak of Ebola since the disease emerged in the 1970s, according to the WHO.

This strain of Ebola is caused by Bundibugyo virus, for which there are no therapeutics or vaccines, the WHO said.

The WHO has declared international public health emergencies over previous Ebola outbreaks as well as COVID-19 and mpox.
