Starting tonight at 11:59 PM EDT, George Bush Intercontinental Airport (IAH) in Houston, Texas, will begin receiving travelers who have been present in the Democratic Republic of Congo (DRC), Uganda, or South Sudan within the last 21 days, directing them toward enhanced federal health screening. The CDC expansion, announced Saturday by the Centers for Disease Control and Prevention, marks a significant escalation in the U.S. government's response to an Ebola Bundibugyo virus outbreak that is rapidly expanding in Central Africa.

Houston joins Washington Dulles (IAD) and Hartsfield-Jackson Atlanta International Airport (ATL) as the only U.S. airports authorized to receive this high-risk traveler pool. The decision to include Houston carries added weight: the DRC national soccer team is scheduled to use the city as its base of operations during the FIFA World Cup 2026, which opens in June across 11 American cities, with DRC's first match scheduled for Houston on June 17.

What Is the Bundibugyo Strain — and Why the Concern?

The Bundibugyo virus is a rare variant of Ebola that has appeared in only two previous documented outbreaks in human history, both in sub-Saharan Africa. It was first identified in 2007 in the Bundibugyo district of Uganda. While considered somewhat less lethal than the more commonly known Zaire strain — which drove the catastrophic 2014-2016 West African epidemic — the Bundibugyo strain still carries an estimated case fatality rate between 25% and 40%, according to the World Health Organization.

Critically, there is currently no approved vaccine or specific antiviral treatment for the Bundibugyo strain. The vaccines and therapeutics developed during the 2014-2016 Ebola crisis — including rVSV-ZEBOV and mAb114 — were designed for the Zaire strain. As Newsweek reported, existing treatments offer limited to no cross-protection. This means the standard toolkit for Ebola response has significant gaps when facing this particular outbreak.

The current outbreak began in the Ituri Province in northeastern DRC. According to WHO Director-General Tedros Adhanom Ghebreyesus, as of late May 2026, there are 82 laboratory-confirmed cases and seven deaths — but Tedros himself cautioned that the true scope is 'much larger,' with at least 750 suspected cases and 177 suspected deaths across the region. Uganda and South Sudan have both reported imported cases originating from the DRC border.

Houston's Particular Exposure — The World Cup Factor

No American city has more at stake this summer than Houston. The World Cup will bring an estimated 1.5 million international visitors to the United States over the course of the tournament, with hundreds of thousands passing through Houston specifically. The DRC national team, along with their coaching staff, support personnel, and thousands of Congolese fans and diaspora community members, is expected to be based in the city for weeks.

According to KHOU 11 News, Houston health officials and infectious disease experts began closely monitoring the Ebola outbreak weeks ago precisely because of this convergence. Dr. John McCullers, dean of the Tilman J. Fertitta Family College of Medicine at the University of Houston, told local media that the Bundibugyo virus is 'highly deadly but does not spread easily,' offering some reassurance about the risk of a mass outbreak event in a stadium setting.

Ebola, unlike measles or COVID-19, is not airborne. It spreads through direct contact with the blood, bodily fluids, or tissues of infected individuals, or through contact with contaminated objects. Healthcare workers and close family caregivers have historically constituted the bulk of infection clusters. A World Cup crowd does not constitute a high-risk transmission environment in the way that a hospital ward or a household would — but the volume of international movement through the city makes vigilant screening an urgent necessity.

The Screening Process: How It Works

Under authority granted by Sections 362 and 365 of the Public Health Service Act, the CDC is implementing a targeted public health travel order in effect for 30 days, with the possibility of extension. American citizens and lawful permanent residents who have been in the DRC, Uganda, or South Sudan within the past 21 days must re-route their flights to arrive at one of the designated airports.

At those airports, Customs and Border Protection (CBP) officers and CDC public health staff conduct structured interviews, temperature checks, and symptom screenings. Travelers displaying symptoms consistent with Ebola — including fever above 101.5°F, severe headache, muscle pain, vomiting, diarrhea, unexplained bleeding or bruising — are referred for immediate medical evaluation and isolation. Non-U.S. nationals from the affected countries are subject to a 30-day travel ban that took effect on May 18.

The U.S. State Department activated a dedicated Ebola Response Task Force led, according to UPI, by 'senior experts with direct experience managing prior Ebola outbreaks' in 2014 and 2018. The department has also deployed a Disaster Assistance Response Team and committed $32 million in assistance to the outbreak response in Africa.

The Broader Question: Is the U.S. Prepared?

Critics and public health analysts have raised pointed questions about the United States' ability to respond to an imported Ebola case in a major metropolitan area, particularly given recent structural changes to the nation's public health apparatus. The country's withdrawal from the World Health Organization, finalized in early 2025, has limited real-time intelligence-sharing that would otherwise flow through WHO's Early Warning channels.

As STAT News observed in an analysis of the situation, the MV Hondius hantavirus outbreak earlier this month demonstrated how quickly disease can travel through global transportation networks — and that the FIFA World Cup amplifies this risk geometrically. Houston, as a designated host city with a specific direct connection to the DRC through the soccer tournament, must be treated as a frontline city in any containment scenario.

For Houstonians and Atlantans, the immediate message from public health officials is calm but clear: there are no confirmed Ebola cases in the United States. The screening program is a precautionary measure, not a crisis response. Residents should not restrict their movements, avoid airports, or panic. Those who have recently returned from the DRC, Uganda, or South Sudan and feel unwell should contact their healthcare provider immediately and inform them of their travel history before arriving at a clinic.
