On May 22, 2026, the Centers for Disease Control and Prevention CDC, an agency within the Department of Health and Human Services HHS, implemented an Amended Order under Sections 362 and 365 of the Public Health Service Act. This significant directive suspends for 30 days the right of certain individuals to enter the United States if they have recently been in the Democratic Republic of Congo DRC, Uganda, or South Sudan. The action is a direct response to a serious public health threat posed by an emergent outbreak of Ebola disease caused by the Bundibugyo virus in these African nations. A critical aspect of this amended order is its removal of an exemption for lawful permanent residents, a notable shift in federal public health policy affecting immigration and international travel.
The Amended Order's Provisions and Policy Shift
The CDC's Amended Order specifically targets individuals referred to as "covered aliens" who have departed from or were present within the DRC, Uganda, or South Sudan within the last 21 days. This 21-day window aligns with the typical incubation period for Ebola. The stated purpose of this temporary suspension is two-fold. First, it aims to immediately reduce the risk of the Bundibugyo virus entering the United States. Second, it grants the CDC a crucial 30-day period to conduct a thorough assessment of the unique public health risks associated with this particular Ebola outbreak. This assessment will inform future decisions regarding necessary restrictions and the development of a comprehensive mitigation and containment strategy in collaboration with various stakeholders.
Perhaps the most impactful change introduced by this Amended Order is the updated stance on lawful permanent residents LPRs. Previously, foreign quarantine regulations under 42 CFR 71.40(f) included an exemption for LPRs. The amended regulations, and consequently this order, now explicitly apply to lawful permanent residents. This signals a broadening of the CDC's authority in situations deemed severe public health emergencies, indicating that the status of permanent residency no longer automatically shields individuals from travel restrictions imposed for communicable disease control.
The Threat of Bundibugyo Virus and Regional Instability
The impetus for this order stems from a confirmed and concerning outbreak of Ebola disease caused by the Bundibugyo virus. This is a rare form of Ebola, initially identified in Uganda in 2007. The Bundibugyo strain presents symptoms similar to other Ebola variants, including fever, weakness, vomiting, diarrhea, and in severe cases, hemorrhagic complications and organ failure. It spreads through direct contact with infected bodily fluids or contaminated materials. Currently, there are no widely approved vaccines or specific antiviral treatments for the Bundibugyo strain, making robust public health measures such as early detection, rapid isolation, stringent infection prevention protocols, and contact tracing critically important for control.
The ongoing outbreak is primarily concentrated in the Ituri Province of eastern DRC. Reports indicate hundreds of suspected cases and dozens of deaths, creating a significant humanitarian and public health crisis. The region's inherent challenges including ongoing conflict, underdeveloped healthcare infrastructure, and permeable borders complicate containment efforts. Uganda has confirmed imported cases, including one in Kampala, originating from travelers from the DRC. While Uganda has prior experience managing Ebola outbreaks, such as the Sudan virus strain in 2025, which bolstered its preparedness, the cross-border nature of the current situation remains a significant concern. South Sudan, despite having no confirmed cases in this specific outbreak, is identified as a high-risk nation due to its geographical proximity to the affected areas of DRC and Uganda, its limited healthcare resources, and substantial cross-border population movements.
Legal Authority and Exceptions to the Order
The CDC exercises its authority to issue this Amended Order pursuant to Sections 362 and 365 of the Public Health Service Act 42 U.S.C. 265, 268, along with their implementing regulations under 42 CFR part 71. These statutes empower the CDC Director to suspend the right of individuals to enter the United States when a quarantinable communicable disease in a foreign country poses a serious risk of introduction into the U.S. and that risk is heightened by the entry of persons from that location. The temporary suspension is thus deemed necessary to safeguard public health.
While broad in its application, the Amended Order does provide specific exemptions. U.S. citizens and U.S. nationals are not subject to these restrictions. Members of the U.S. armed forces, associated personnel, U.S. government personnel serving overseas, and their spouses and children are also exempt under certain assurances. Additionally, customs officers, with supervisory approval, can make exceptions based on the totality of circumstances, which may include significant law enforcement, public safety, humanitarian, or public health interests. Non-citizens who would otherwise be covered may also be permitted entry if approved by the Department of Homeland Security DHS through processes that include appropriate mitigation protocols, shared and documented with the CDC. These exceptions underscore a recognition that blanket prohibitions can have unforeseen consequences and that a degree of flexibility is needed for various national interests.
Broader Implications and Future Outlook
The CDC's Amended Order reflects a proactive, albeit stringent, approach to managing potential transboundary public health threats. The 30-day period is presented as a critical window for federal agencies to gather more data, refine risk assessments, and coordinate a comprehensive strategy. The move to include lawful permanent residents in such a temporary travel suspension marks a notable expansion of public health powers during emergencies. It suggests a federal willingness to prioritize population-level health protection over certain individual travel rights when faced with serious communicable disease risks.
The challenges facing the international community in containing the Bundibugyo outbreak in Central Africa remain substantial. The intertwined issues of conflict, weak governance, and limited health infrastructure create a complex environment for disease control. The CDC's action underscores the interconnectedness of global health and national security, highlighting how outbreaks in distant regions can necessitate immediate and far-reaching policy responses within the United States. The upcoming month will be crucial in determining the longer-term trajectory of U.S. policy regarding this Ebola threat, as the CDC concludes its assessment and potentially revises its guidance or extends the order.
