CDC Ebola entry restrictions tied to the ongoing 2026 Central Africa outbreak remain in effect for travelers who have recently been in the Democratic Republic of the Congo, Uganda or South Sudan. The Centers for Disease Control and Prevention first issued the order on May 18, 2026. It has renewed the order monthly since — most recently on August 12, 2026, for a 30-day period — according to the CDC’s own order text.
The measure suspends U.S. entry for foreign nationals who were physically present in any of the three countries within the preceding 21 days. The CDC maintains guidance on assessing and managing affected travelers on its emergency guidance page.
Who the CDC Ebola Entry Restrictions Actually Cover
The order exempts U.S. citizens and nationals outright. Military personnel and U.S. government employees serving overseas are exempt too. Everyone else who has been in the DRC, Uganda or South Sudan within 21 days of a scheduled flight cannot board a commercial flight to the United States. The rule applies regardless of the traveler’s ultimate nationality, as long as they are not a U.S. citizen or national.
People already inside the United States face a different set of rules. Those who recently returned from an affected country get screening and monitoring, not an entry bar, under separate CDC guidance. The restriction targets boarding a flight to the U.S. It does not target movement within the country after arrival. Nobody who departed an affected country more than 21 days earlier needs any monitoring at all.
Airlines connecting through the region check travel history before allowing boarding. That puts the practical enforcement point at the departure gate, not on arrival in the United States. A traveler who has been in an affected country within the 21-day window should expect a turn-away at check-in, not at U.S. immigration.
Why the CDC Keeps Renewing the Ebola Entry Restrictions
The order has been renewed four times since May, in June, July and August, each for roughly a 30-day window. That reflects the CDC’s usual approach: tie the restriction’s duration to the outbreak’s active status, rather than issue it as a one-time, open-ended measure. New cases in the DRC keep the restriction alive. Expect it to keep getting extended on a similar rolling basis as long as the 2026 Central Africa Ebola epidemic continues.
This travel measure is one of several disruptions affecting international travel in recent weeks. Tamara News has also covered airline disruptions tied to the security situation around Beirut and the potential effects of a U.S. government shutdown on air travel. All three are part of a broader pattern of travel friction building heading into the fall.
What Travelers From Affected Countries Should Know
Anyone planning U.S. travel who has recently been in, or plans to visit, the DRC, Uganda or South Sudan should check the order’s current status before booking. The 21-day exposure window counts physical presence in the country. It does not depend on intent to travel onward from a third country. The State Department’s consular guidance is the authoritative source for the order’s current expiration date and any updates.
Travelers with connecting flights through the region face particular risk of confusion. A layover inside an affected country still counts as physical presence there, even if the traveler never leaves the airport. Anyone routing through Kinshasa, Entebbe or Juba on the way to the U.S. should confirm their specific itinerary against the order’s exact wording. A short layover is not automatically safe.
Travel agents and airline staff booking multi-leg itineraries through Central and East Africa have had to build this restriction into their standard screening checklists. A routing that looked routine six months ago can now trigger an automatic denial at check-in. That is why airlines have leaned on the 21-day rule so heavily in their own booking systems. Most now flag affected itineraries well before a traveler ever reaches the airport.
How Long the Ebola Restrictions Could Last
The current order, issued August 12, runs for roughly 30 days. That puts its next renewal decision around mid-September 2026. Whether the CDC extends it again depends directly on whether new Ebola cases keep appearing in the DRC. That is the same pattern driving four consecutive monthly renewals so far. Travelers with upcoming plans should check back around that mid-September window for the next update.
