IOM Races to Contain Cholera Outbreak as Refugee Surge Strains South Sudan’s Health System

The International Organization for Migration (IOM) has accelerated its response to a critical cholera outbreak in Renk, Upper Nile state, a primary entry point for refugees fleeing the ongoing conflict in Sudan. As a transit hub where over 13,000 arrivals currently seek shelter, Renk now faces heightened public health risks as cholera spreads among vulnerable populations.

The outbreak was declared by South Sudan’s Ministry of Health following the confirmation of six cholera cases, with 59 additional suspected cases reported. Health authorities warn the situation is severe, particularly given the challenging conditions in transit centers and host communities.

"The response team on the ground is working tirelessly to ensure that those affected receive the necessary care and support, while preventive measures are being implemented to limit further spread,” said Aaron Adkins, IOM's Emergency Response Coordinator in South Sudan.

The arrival of displaced people in overcrowded areas with limited sanitation and clean water access has intensified the transmission risk. In response, IOM has launched a coordinated emergency strategy, working closely with South Sudanese health authorities and partner organizations to curb the outbreak.

More than 684,000 people escaping the Sudan conflict have entered South Sudan through the Wunthuo Point of Entry (PoE) in Renk. To address the situation, IOM has mobilized resources at the PoE and other key locations, deploying trained clinicians to transit centers in both Renk and Malakal. Medical teams support the swift identification and management of cholera cases, while Oral Rehydration Points (ORPs) have been set up to provide life-saving treatment for affected individuals.

A critical aspect of IOM’s approach involves robust risk communication, with teams actively educating communities about cholera prevention, hygiene practices, and the need for prompt treatment. This public health outreach empowers community members to adopt preventative measures essential for containing the disease.

To further support the local health infrastructure, IOM has trained clinicians in case identification and the application of rapid diagnostic tests. These capabilities are vital for enabling swift detection and treatment, which remain crucial in reducing the spread of cholera in this emergency setting.

In tandem with healthcare interventions, IOM’s response includes essential water, sanitation, and hygiene (WASH) initiatives. Those receiving Onward Transportation Assistance (OTA) are also briefed on cholera prevention measures, adding a further layer of precaution as they continue their journeys.

The outbreak in Renk poses a significant challenge for newly displaced individuals already facing severe hardship. Under the leadership of the public health emergency operations center, IOM is working alongside humanitarian partners to contain the outbreak and protect those most at risk.
