A fast-moving Ebola outbreak in Central Africa has pushed U.S. health officials into emergency mode. The Centers for Disease Control and Prevention has rapidly expanded CDC Ebola screening across major American airports, targeting travelers arriving from the Democratic Republic of Congo (DRC), Uganda, and South Sudan. The move comes as global health experts race to contain a dangerous new wave of the deadly virus.
What Triggered the CDC’s Urgent Response?
On May 5, 2026, the World Health Organization received an alert about a high-mortality illness outbreak in Mongbwalu Health Zone, Ituri Province, in the DRC. Laboratory analysis later confirmed the presence of Bundibugyo virus disease, a species of Ebola. WHO
On May 15, the DRC’s Ministry of Health officially declared the country’s 17th Ebola outbreak since 1976. The speed of spread alarmed officials immediately. WHO
Critically, there is no licensed vaccine or specific treatment for the Bundibugyo strain, though early supportive care has proven lifesaving. That gap made containment even more urgent. WHO
A Public Health Emergency of International Concern
On May 17, 2026, WHO Director-General declared the Ebola outbreak in the DRC and Uganda a Public Health Emergency of International Concern (PHEIC). This is one of the highest alert levels in global health. WHO
As of May 27, 2026, over 1,200 suspected and confirmed cases and at least 264 deaths had been reported — and experts warn the true number of infections may be far higher. Wikipedia
Which U.S. Airports Now Conduct CDC Ebola Screening?
The CDC has moved swiftly to expand its airport screening network. Therefore, travelers arriving from affected countries now face stricter health checks at multiple entry points.
Screening began at Washington Dulles International Airport on May 20, 2026, at 11:59 PM Eastern Time, targeting travelers who had been in DRC, Uganda, or South Sudan within the previous 21 days. CDC
The CDC then expanded enhanced public health entry screening to Hartsfield-Jackson Atlanta International Airport on May 22, 2026. CDC

The three designated airports are now:
- Washington Dulles International Airport (IAD) — operational since May 20
- Hartsfield-Jackson Atlanta International Airport (ATL) — operational since May 22
- George Bush Intercontinental Airport, Houston (IAH) — operational since May 26
CDC Calls for Volunteer Screeners
The agency is also scaling up its staffing. The CDC is seeking volunteers from its own workforce to help screen international travelers at domestic airports, prioritizing so-called CDCReady Responders, according to an internal email reviewed by Bloomberg News. Bloomberg

What Happens During Entry Screening?
CDC Ebola screening at airports follows a clear, structured process. Travelers from affected countries go through several steps:
CDC officers collect contact information for follow-up by state or local public health authorities if needed. Some travelers may also receive an additional public health assessment depending on their specific exposure history. CDC
Additionally:
- Travelers without symptoms receive guidance on monitoring their health for 21 days after leaving affected countries.
- Travelers who show fever or other symptoms that could indicate Ebola receive further evaluation by a CDC public health officer. CDC
- Most travelers without symptoms continue to their final destination after screening.
Travelers should monitor themselves for Ebola symptoms for 21 days after leaving affected countries. Anyone who develops symptoms should avoid travel and contact public health authorities immediately. CDC
Entry Restrictions for Foreign Nationals
Beyond screening, the U.S. government has also tightened entry rules.
On May 18, 2026, the CDC issued an Order suspending entry to the United States of foreign nationals who had been in the DRC, Uganda, or South Sudan within 21 days before arrival. Usembassy
However, U.S. citizens, nationals, and lawful permanent residents still retain the right to enter. Travelers in these categories who had been in the affected countries are redirected to designated airports for enhanced public health screening. CDC
The CDC has also invoked Title 42, a public health law that restricts U.S. entry during communicable disease outbreaks, for at least 30 days starting May 20. CNN
How Serious Is the Outbreak Right Now?
The current outbreak is spreading unusually fast. Health experts were alarmed that the outbreak had already reached hundreds of suspected cases by the time it was first publicly reported on May 15. Wikipedia
The epidemic is caused by the Bundibugyo ebolavirus, which may complicate response efforts, since existing Ebola treatments have largely been developed and tested against the Zaire ebolavirus strain. Wikipedia
As of May 26, the DRC reported over 1,077 suspected cases and 238 suspected deaths, along with 121 confirmed cases and 17 confirmed deaths across multiple provinces, including Ituri, North Kivu, and South Kivu. Uganda has reported seven confirmed cases, including one death. europa
Meanwhile, the CDC noted that the risk to the American public remains low, as Ebola spreads through direct contact with infected bodily fluids and does not spread through casual contact or air. CDC
Is the U.S. at Risk?
To date, no suspected, probable, or confirmed cases of Ebola have been reported in the United States, and the domestic risk remains low. CDC
Nevertheless, officials stress that caution is still warranted. Because people exposed to Ebola may travel before symptoms begin, the CDC is implementing layered prevention measures to reduce the risk of spread into the country. CDC
These layered measures include overseas exit screening, airline illness reporting, airport entry screening, and post-arrival public health monitoring. CDC
Background: What Is the Bundibugyo Strain?
Not all Ebola strains are identical. Therefore, understanding the Bundibugyo virus matters for both public health officials and travelers.
The case fatality rate in the two previous Bundibugyo virus outbreaks ranged from 30% to 50%. That makes it highly lethal, though somewhat less deadly than the Zaire strain seen in West Africa’s 2014–2016 mega-outbreak. WHO
This marks the DRC’s 17th Ebola virus outbreak since 1976 and its second outbreak caused specifically by the Bundibugyo virus. CDC
Conclusion
The CDC’s rapid expansion of Ebola screening at U.S. airports reflects the seriousness of the ongoing outbreak in Central Africa. However, health officials continue to emphasize that the domestic risk remains low. Travelers returning from the DRC, Uganda, or South Sudan should expect additional health checks upon arrival and must monitor themselves for symptoms for three weeks.
As the outbreak evolves, the CDC is expected to adjust its response accordingly. Therefore, travelers should check the CDC’s official website regularly for the latest guidance on affected regions and screening requirements.
