WHO urges Uganda to reconsider Congo border closure over Ebola outbreak

Uganda's recent decision to temporarily close its border with the Democratic Republic of Congo (DRC) in response to an Ebola outbreak has sparked a critical legal and public health debate, with the World Health Organization (WHO) urging reconsideration. This article examines the legal framework governing such actions, specifically the interplay between Uganda's domestic public health legislation, primarily the Public Health Act (Cap 281), and its obligations under the International Health Regulations (IHR) 2005. While states possess sovereign rights to protect their populations, the IHR mandates that public health measures impacting international traffic must be evidence-based, proportionate, and avoid unnecessary interference. The WHO's consistent position against blanket travel restrictions for Ebola highlights the complexities practitioners face in advising governments on balancing national security with international legal commitments during cross-border health emergencies.

In early June 2026, the Director-General of the World Health Organization (WHO), Dr. Tedros Adhanom Ghebreyesus, publicly urged Uganda to reconsider its decision to temporarily close its border with the Democratic Republic of Congo (DRC). This appeal followed Uganda's announcement in late May 2026 to restrict movement across the border as a measure to curb the spread of an ongoing Ebola outbreak, specifically the Bundibugyo strain, which the WHO had declared a Public Health Emergency of International Concern (PHEIC).

This development underscores a recurring tension in international public health law: the delicate balance between a sovereign state's inherent right and duty to protect its citizens from infectious diseases and its binding obligations under international instruments designed to facilitate global cooperation and minimize disruptions to international traffic and trade. For legal practitioners, navigating this landscape requires a nuanced understanding of both domestic public health statutes and the overarching international health regulations. This article will delve into the legal justifications and constraints surrounding Uganda's border closure, analyzing the relevant domestic and international legal frameworks to illuminate the complexities involved.

Uganda's domestic legal framework for public health emergencies is primarily anchored in the Public Health Act, Cap 281 of the Laws of Uganda. Enacted in 1935 and subsequently re-codified, this Act grants broad powers to the Minister of Health and local authorities to take measures for the prevention and suppression of infectious diseases. Specifically, Part VI, Section 36 of the Public Health Act empowers authorities to enforce precautions at borders to prevent the introduction of infectious diseases. The Act also allows the Minister to declare diseases as 'notifiable' or 'epidemic' and to make rules for their prevention.

Internationally, Uganda is a State Party to the International Health Regulations (IHR) 2005, a legally binding instrument adopted by the World Health Assembly. The IHR's purpose is to prevent, protect against, control, and provide a public health response to the international spread of disease in ways that are commensurate with and restricted to public health risks, while avoiding unnecessary interference with international traffic and trade. The IHR outlines specific obligations for States Parties, including developing core public health capacities, notifying the WHO of public health events, and implementing health measures at points of entry. Crucially, while States Parties can implement additional health measures that interfere with international traffic, these measures must be based on scientific principles, evidence, and a public health rationale, and must be notified to the WHO.

Uganda's decision to close its border with the DRC, while seemingly a direct exercise of its sovereign power to protect public health under the Public Health Act (Cap 281), must be assessed against its international obligations under the IHR 2005. The Public Health Act, particularly Section 36, provides a domestic legal basis for enforcing precautions at borders to prevent disease introduction. This power was notably utilized during the COVID-19 pandemic, where the Public Health Act was the primary legislation for implementing non-pharmaceutical interventions, including border controls.

However, the IHR 2005, to which Uganda is a signatory, places significant constraints on such measures. Article 43 of the IHR permits States Parties to implement additional health measures that interfere with international traffic, but these measures must be non-discriminatory, based on scientific principles and available evidence, and must not be more restrictive than reasonably available alternatives to achieve the appropriate level of health protection. Furthermore, any such measures that significantly interfere with international traffic must be reported to the WHO, along with the public health rationale and evidence.

The WHO's consistent stance, reiterated by Director-General Tedros, is that blanket travel restrictions are generally ineffective in containing Ebola and can have severe negative economic and social consequences. This position is rooted in epidemiological evidence suggesting that such measures often only delay disease introduction by a short period and can hinder response efforts by impeding the movement of essential personnel and supplies. The IHR's emphasis on avoiding "unnecessary interference with international traffic and trade" directly reflects this understanding. While the WHO acknowledged during the COVID-19 pandemic that some travel measures, when integrated with other interventions, could be warranted, its general advice for known diseases like Ebola remains against broad restrictions.

The tension arises when a state's perceived immediate national interest in disease containment, as reflected in its domestic legislation, clashes with international recommendations aimed at a more globally coordinated and less disruptive response. Uganda's action, while perhaps domestically justifiable, faces scrutiny under the IHR for proportionality, scientific basis, and potential for unnecessary interference. The exemption of humanitarian operations, Ebola response teams, security personnel, and cargo transportation from Uganda's restrictions indicates an attempt to mitigate some of the negative impacts, but the core measure of border closure still invites the WHO's call for reconsideration.

The situation involving Uganda's border closure and the WHO's urging for reconsideration exemplifies the complex legal and ethical tightrope walked by states during cross-border public health emergencies. While national sovereignty grants states the power to enact measures like border closures under domestic laws such as Uganda's Public Health Act, these actions are simultaneously governed by international instruments like the IHR 2005. The IHR prioritizes evidence-based, proportionate responses that minimize disruption to international traffic, a principle often at odds with immediate, broad restrictive measures.

For legal practitioners, this case highlights the critical need to advise governments on the dual legal obligations – domestic and international – when formulating public health responses. It underscores the importance of transparent communication with international bodies, providing scientific justification for measures, and exploring less restrictive alternatives. As global interconnectedness increases the risk of rapid disease spread, the ongoing dialogue between national public health imperatives and international health regulations will continue to shape the legal landscape, demanding harmonized, evidence-informed, and human rights-respecting approaches to safeguard both national and global health security.
