A Paper Trail at the Border
Starting 3 November, every person flying into the United States will need to fill out a declaration stating they have not set foot in the Democratic Republic of Congo during the previous three weeks. The attestation can be submitted digitally or on paper, according to guidance issued this week by the US Centres for Disease Control and Prevention.
The move marks an expansion of rules introduced in May, when the CDC first restricted entry for airline passengers with recent exposure to the DRC, the epicentre of this year's outbreak. Those initial measures targeted foreign nationals; by July, the restrictions had been broadened to include American citizens as well. The new attestation requirement adds a formal documentation layer to enforcement, creating a record of each traveller's recent movements.
Airlines operating US routes will receive detailed compliance instructions during briefing calls scheduled with the CDC on Friday. Major American carriers, including United, American, Southwest and Delta, have not yet commented publicly on the operational implications of the new rule.
The Outbreak Behind the Rules
The 2026 Ebola outbreak has been driven by the Bundibugyo strain, a variant that circulated undetected for months before health authorities formally declared an emergency in May. According to the Africa Centres for Disease Control and Prevention, the outbreak has claimed approximately 4,700 lives across the continent. The Bundibugyo strain is particularly dangerous, killing roughly half of those it infects, and currently has no approved treatment or vaccine available.
The lack of a medical countermeasure means containment relies almost entirely on surveillance, isolation and movement tracking. That reality has pushed governments to implement travel restrictions as a first line of defence, even as public health experts debate their effectiveness. The US approach has been to layer entry bans, regional screening and now mandatory attestations, creating multiple checkpoints that travellers from affected areas must clear.
So far, no cases linked to this outbreak have appeared in the United States, according to the CDC. That record reflects both geographic distance and the relatively limited air connectivity between central Africa and North America. Most travellers from the DRC to the US transit through European or Middle Eastern hubs, where screening measures are also in place.
Who Is Covered, and How
The attestation requirement applies universally to anyone boarding a US-bound flight, regardless of nationality or visa status. Travellers will need to confirm they have not been physically present in the DRC within 21 days of their arrival. That three-week window corresponds to the maximum incubation period for Ebola, the span during which symptoms can develop after exposure.
The CDC's existing entry restrictions go further for certain groups. Foreign nationals who have been in Uganda or South Sudan during the prior three weeks are barred from entering the United States altogether. Those two countries were added to the restricted list earlier this year after cases were detected near their borders with the DRC. American citizens and permanent residents, however, are not subject to outright bans, they face enhanced screening and monitoring instead.
The distinction matters. While attestations create a documentary trail, they rely on self-reporting. Passengers could, in theory, provide false information, though doing so carries legal consequences under US law. The CDC has not detailed how it will verify attestations, nor whether spot checks or follow-up interviews will be part of the process. Airlines, meanwhile, will be responsible for ensuring that every passenger completes the form before boarding, adding another task to check-in procedures.
Implications for Travel Flows
For most travellers, the attestation will be a minor administrative step, a checkbox on a digital form or a signature on a printed sheet. But for those with legitimate reasons to travel through or from affected regions, whether for business, family or humanitarian work, the expanding web of restrictions is becoming harder to navigate.
The DRC is not a major source market for US tourism, but it is home to international organisations, mining companies and aid groups that employ staff from around the world. Workers rotating in and out of the country now face the prospect of three-week quarantine periods or rerouted itineraries if they want to travel onward to the United States. That disruption has ripple effects for project timelines, staffing and costs.
Neighbouring countries are feeling the pressure too. Uganda and South Sudan, both significant transit points and economic partners in the region, have seen their connectivity to the US curtailed. The CDC's decision to include them in the restricted list reflects a precautionary principle, one that prioritises containment over convenience. Whether that trade-off is justified depends on the outbreak's trajectory in the coming months.
The Broader Context of Health Screening
The United States has a long history of using travel restrictions to manage infectious disease threats, from tuberculosis screening for immigrants to the more recent pandemic-era entry bans. The current Ebola measures sit somewhere in the middle of that spectrum: more targeted than blanket country bans, but broader than the focused quarantine protocols used for individual suspected cases.
Other countries have adopted their own versions of screening and attestation. European nations with direct flights from central Africa have implemented temperature checks and questionnaires at arrival, while some Asian countries have required health certificates for travellers transiting through affected regions. The patchwork of rules creates confusion for passengers and airlines alike, particularly when requirements change with little notice.
The CDC's move to formalise attestations may be an attempt to standardise the process, giving both travellers and carriers a clear set of expectations. But it also raises questions about enforcement and accuracy. Health declarations are only as reliable as the information travellers provide, and the consequences of false statements are rarely publicised or tested in practice.
What Happens Next
The November deadline gives airlines just over a week to update their systems and train staff on the new requirements. For carriers already managing a complex web of visa, vaccination and entry rules, the attestation adds another layer of compliance. It is unclear whether the CDC will provide standardised forms or leave the design to individual airlines, a detail that will matter for passengers navigating check-in processes.
If the outbreak continues to spread or new cases emerge in additional countries, the US may expand its restricted list or tighten screening further. The CDC has shown a willingness to adjust its measures as conditions change, a flexibility that reflects both the unpredictable nature of infectious disease and the political pressure to be seen acting decisively.
For now, the attestation requirement is a signal that the US government views the outbreak as an ongoing risk, even in the absence of domestic cases. Whether the measure proves effective will depend on factors beyond any single policy: the course of the outbreak in Africa, the capacity of health systems in affected countries and the willingness of travellers to comply with rules that may feel distant from their own experience.
