US Ebola Travel Restrictions Explained: The 21-Day Rule, the Four Screening Airports, and What It Means for Your East Africa Trip

On August 12, 2026, CDC renewed its order under 42 CFR 71.40 continuing temporary US entry restrictions for certain travelers who have recently been in the Democratic Republic of the Congo, Uganda, or South Sudan. Six days later, on August 18, the WHO Director-General told the second IHR Emergency Committee meeting on this outbreak that the Bundibugyo virus epidemic in DRC is now the second-largest Ebola outbreak ever recorded, and the fastest-moving.

Our providers have fielded the same three questions from travelers all month. Can I still fly home? Will I be stopped at the airport? Should I cancel my safari? This article answers those directly, using CDC's own published rules rather than headlines.

The short version: the hard boarding ban applies to DRC only. Uganda and South Sudan trigger rerouting and a brief screening, not a bar on travel. And the practical risk to a typical leisure traveler in East Africa has not changed much. What has changed is how much your flight routing matters.

What the August 12 order actually does

CDC's traveler guidance, last reviewed August 12, 2026, splits travelers into two groups with very different rules.

If you have been in DRC within the previous 21 days, you will not be allowed to board a commercial flight with a US destination. This applies to US citizens and US nationals as well as everyone else. CDC's language is unusually specific on one point that catches people out: the restriction applies to passengers with an intermediate stop in DRC or on multi-stop itineraries via DRC, regardless of whether they disembarked or stayed on the airplane. A technical stop counts.

The practical consequence is that you must plan to remain outside the United States for the full 21 days after leaving DRC, and you may return beginning on day 22. CDC has published a timeline graphic for exactly this reason. If you leave the United States mid-monitoring after having been in DRC, you will not be permitted to return until the 21 days have elapsed.

If you have been in Uganda or South Sudan but not DRC, travel by US citizens and nationals is not restricted. Your flight is rerouted to a designated US airport for public health entry screening, and CDC notes that this applies even if you only passed through on a connecting flight. Airlines work with affected travelers to rebook where needed.

South Sudan is included not because of a known outbreak there. CDC's interim guidance states there is no specific area of concern identified in South Sudan, and it is covered because it neighbors DRC with high-volume travel across a porous shared border.

The four screening airports

Travelers who have been in South Sudan or Uganda in the past 21 days and are permitted to enter the US will undergo public health entry screening at one of four airports:

• Washington Dulles International Airport (IAD)
• Hartsfield-Jackson Atlanta International Airport (ATL)
• George Bush Intercontinental Airport (IAH), Houston
• John F. Kennedy International Airport (JFK), New York

If you left DRC, South Sudan, or Uganda more than 21 days before travelling to the United States, CDC states you will not need to undergo entry screening at all. This is the single most useful planning detail in the whole order. A traveler who spends three weeks elsewhere before flying home skips the process entirely.

What screening actually feels like

The word "screening" makes people picture something far more dramatic than what CDC describes. Per CDC's published process, travelers will:

• Be escorted to a screening area
• Complete a brief questionnaire about travel history and symptoms
• Have their temperature checked
• Be observed for signs of illness by CDC staff
• Be enrolled in automated text messages from CDC reminding them to monitor their health for 21 days after leaving the affected country

Most travelers without symptoms continue to their final destination after screening. Some travelers get an additional public health assessment based on where they went and what they did there. CDC also shares traveler contact information with state or local public health authorities for follow-up.

If you do have fever or other symptoms consistent with Ebola at the point of entry, a CDC public health medical officer conducts a further evaluation, and if Ebola is suspected you are transferred to a hospital for evaluation, isolation, and care.

What monitoring looks like after you get home

This is the part travelers underestimate, and it differs by where you were.

If you were in DRC and were granted an exception to travel, CDC recommends daily self-monitoring including a daily temperature measurement for 21 days. Health departments are advised to monitor these travelers twice daily in person, and travelers are told to stay home, avoid others, delay nonurgent medical and dental care, and limit travel to essential purposes by noncommercial means.

If you were in Uganda or South Sudan, the standard is much lighter. Watch your health for 21 days, take your temperature if you feel sick, and notify your health department if symptoms develop. Health departments may do a single optional check-in. CDC's guidance does add that these travelers should reconsider international travel and cruise ship travel during the monitoring window, because of uncertainty about restrictions and healthcare access in destination countries.

The symptoms CDC tells travelers to watch for are fever of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher or feeling feverish, headache or body aches, rash, weakness or tiredness, sore throat, diarrhea, vomiting, stomach pain, and unexplained bleeding or bruising, which is a late-stage sign.

Why the response scaled up in August

The restrictions tightened because the outbreak did. Data compiled by the WHO Regional Office for Africa through August 16, 2026 put the outbreak at 5,021 confirmed cases and 2,378 deaths, with 751 patients hospitalised in isolation and 1,061 recovered. Ituri province is worst hit with 4,257 cases and 1,878 deaths reported from 28 of its 36 health zones. North Kivu has recorded 607 cases and 428 deaths across 12 of 34 health zones.

For scale, DRC's 2018 to 2020 outbreak recorded 3,317 confirmed cases. This one has already passed that.

WHO's August 18 assessment attributed the spread to insecurity, displacement, and intense population movement along roads, rivers, and mining routes, and stated bluntly that the epidemic is far from being under control.

There is one genuinely encouraging line in that same assessment. Two vaccines designed specifically against Bundibugyo virus have entered human trials, and a separate vaccine showing cross-protection in animal studies has been proposed for a phase III trial. Nothing there is available to a traveler booking a trip today, but the pipeline is moving.

Where CDC's travel notices actually sit

It is worth separating the entry order from the travel health notices, because they are different instruments and people conflate them.

CDC escalated the notice for Ituri and North Kivu provinces of DRC to Level 4, avoid all travel, on August 4, 2026. A Level 3 notice, reconsider nonessential travel, covers South Kivu, Haut-Uele, and Tshopo provinces. The rest of DRC and all of Uganda sit at Level 2, practice enhanced precautions.

Uganda's own outbreak is over. Uganda's Ministry of Health declared it ended on July 28, 2026, and CDC's August 6 assessment recorded no current area of concern in Uganda, noting that more than 21 days had passed since the last Ugandan patient was discharged after two negative tests and more than 42 days since that patient was isolated, which CDC called highly suggestive that community transmission is not occurring.

That is the sentence to hold onto if you have a Bwindi gorilla permit booked.

What this means for a normal safari or trekking trip

For most travelers the honest answer is: check your routing, then get on with your trip planning.

Ebola does not spread through casual contact or through the air. It spreads through direct contact with blood or body fluids of a person who is sick with or has died from the disease, and through contaminated objects and infected animals. The exposure situations CDC flags in its assessment tool are visiting a health care facility or traditional healer, attending a funeral or burial, contact with a person with acute febrile illness, and contact with bats or non-human primates or entry into caves and mines. A lodge-based safari itinerary involves none of these.

Three practical planning moves:

Audit your flight routing, including layovers. A DRC technical stop turns into a 21-day problem. Check every leg, not just your origin and destination.

Build a buffer if your itinerary touches an affected country. Twenty-one days outside the US after DRC is a long buffer, but 21 days between leaving Uganda and flying home means no screening at all.

Do not let the headline crowd out the actual risks. The health problems that reliably affect East Africa travelers are malaria, traveler's diarrhea, and altitude on Kilimanjaro, and all three are preventable with pre-trip prescriptions. Our full Ebola outbreak guide for East Africa travelers covers the clinical background, and the Uganda travel health guide covers what your trip actually requires.

The prep that matters more than the headline

Malaria is the risk that should occupy your planning attention. Both Uganda and Tanzania are high-transmission destinations, and CDC data shows roughly 2,000 malaria cases reported in the United States each year, almost all of them imported by travelers, with an average of nearly 7 deaths per year between 2007 and 2022. CDC has also reported that 95% of people diagnosed with malaria had not taken appropriate malaria prevention medication.

Atovaquone-proguanil (Malarone) is the antimalarial most of our East Africa patients end up on, because the dosing window is forgiving: start one to two days before entering the risk area and continue seven days after leaving, rather than the four weeks that some alternatives require. Our providers review your itinerary and call the prescription in to a pharmacy near you.

The second thing worth having in hand is an antibiotic for traveler's diarrhea. Azithromycin is our usual choice for East Africa, and it matters here for a reason beyond comfort: a traveler carrying a treatment they can start themselves is less likely to end up in a clinic waiting room in an outbreak region, which is exactly one of the exposure situations CDC's screening tool asks about.

And if any of your monitoring period overlaps with the trip itself, know the difference between fever that needs a same-day workup and fever that can wait. That distinction is the whole subject of our companion piece on what to do when you develop a fever after international travel, which walks through the first 24 hours and why malaria, not Ebola, is the diagnosis that most often gets missed.

Insurance is the underrated line item this year

Entry restrictions can change with days of notice, as the August 12 renewal showed. That makes trip interruption and medical evacuation coverage a genuinely different calculation for an East Africa trip in 2026 than it was two years ago.

Two things to check before you buy rather than after. First, the epidemic and pandemic exclusion language, which is where most outbreak-related claims die. Second, the timing rule, because once an outbreak is public knowledge many carriers treat it as a foreseeable event and exclude it for policies bought afterward. Our guide on whether you actually need travel insurance works through when the math favors buying it.

The calm bottom line

The 2026 Bundibugyo outbreak is a serious public health emergency in DRC and a genuine strain on the region. It is not, for a leisure traveler on a lodge-based safari in Uganda, Kenya, or Tanzania, a reason to cancel.

What it is, is a reason to read your flight itinerary carefully, expect a temperature check and a text-message enrollment if you route through Uganda or South Sudan, and put your actual medical prep, antimalarials and a traveler's diarrhea antibiotic, in place before you go.

Frequently asked questions

Can I still fly to the United States from the DRC in 2026?

No, not on a commercial flight. Under CDC's temporary entry restriction, renewed August 12, 2026 under 42 CFR 71.40, travelers who have been in DRC within 21 days before departure, including US citizens and US nationals, will not be allowed to board a commercial flight with a US destination. CDC's guidance is explicit that this applies even if you only had an intermediate stop in DRC and never left the aircraft. You may return beginning on day 22 after leaving DRC.

Which US airports are doing Ebola entry screening?

Four. CDC lists Washington Dulles International (IAD), Hartsfield-Jackson Atlanta International (ATL), George Bush Intercontinental in Houston (IAH), and John F. Kennedy International in New York (JFK). Travelers who have been in Uganda or South Sudan in the previous 21 days have their flights rerouted through one of these four, and airlines rebook affected passengers where needed.

Is it safe to travel to Uganda right now?

Uganda's Ministry of Health declared its Bundibugyo outbreak over on July 28, 2026, and CDC's August 6 assessment found no current area of concern in Uganda, noting that more than 42 days had passed since the last patient was isolated. CDC still lists Uganda at a Level 2 travel health notice, meaning practice enhanced precautions, and arrivals from Uganda are still routed through screening airports as a precaution. Gorilla trekking and safari itineraries in Uganda are operating.

What actually happens at public health entry screening?

CDC describes a short, structured process: you are escorted to a screening area, complete a brief questionnaire about travel history and symptoms, have your temperature checked, are observed for signs of illness by CDC staff, and are enrolled in automated CDC text messages that remind you to monitor your health for 21 days. Most travelers without symptoms continue straight on to their final destination.

How big is the 2026 Bundibugyo outbreak?

As of data through August 16, 2026, the WHO Regional Office for Africa reported 5,021 confirmed cases and 2,378 deaths across six provinces and 55 health zones in DRC, with Ituri province worst affected at 4,257 cases and 1,878 deaths. Speaking at the second IHR Emergency Committee meeting on August 18, 2026, the WHO Director-General described it as the second-largest Ebola outbreak ever recorded and the fastest-moving.

Is there an Ebola vaccine that protects against this outbreak?

Not an approved one. The licensed Ebola vaccines target Zaire ebolavirus, and CDC states plainly that no vaccines or specific treatments have been approved to prevent or treat Bundibugyo virus disease. WHO reported on August 18, 2026 that two vaccines designed specifically against Bundibugyo virus have entered human trials and a third showing cross-protection in animal studies has been proposed for a phase III trial. None is available to travelers today.

Does travel insurance cover a trip cancelled because of these restrictions?

It depends entirely on the policy and on when you bought it. Standard policies often exclude foreseeable events once an outbreak is publicly known, while cancel-for-any-reason upgrades and some policies with epidemic coverage are broader. Read the epidemic and pandemic exclusion language before you buy rather than after, and buy early, since coverage for a known event is usually the first thing carriers exclude.

Do I need to do anything special if I am only flying through Nairobi or Addis Ababa?

No. The restrictions attach to presence in DRC, Uganda, and South Sudan. Kenya and Ethiopia are not affected countries under CDC's August 2026 interim guidance, and a connection through Nairobi or Addis Ababa does not by itself trigger rerouting or screening.
