A joint statement released on Tuesday said that a total of 2,555 cases and 32 deaths have been reported since October 28, with about 37% of cases affecting children.
About 150,000 people in Renk County are set to receive life-saving vaccinations, procured and delivered with UN support.
Over a million more vaccine doses will reach people across the country, including in the capital, Juba.
“This effort is part of a wider campaign involving the government, UN agencies, NGOs, and partners, focused on delivering healthcare, clean water provision, and hygiene promotion,” the statement said.
The outbreak is impacting refugees, returnees, and residents alike, with children under five and older people particularly vulnerable.
Yolanda Awel Deng, South Sudan’s Minister of Health, said these vaccinations are vital to protect the population.
“I call upon the public, health professionals, and community leaders to make the campaigns a success while taking every possible measure to prevent the spread of the disease,” she said.
Anita Kiki Gbeho, the UN Humanitarian Coordinator for South Sudan, said the cholera outbreak response requires a coordinated and urgent multi-sectoral approach, extending far beyond the health sector.
“The UN is committed to working closely with the Government of South Sudan to ensure inclusive coordination, clear public communication, and transparent data sharing, essential for effective preparedness, readiness, and response,” Gbeho said.
Vaccination is just one part of a multi-sectoral response and the most cost-effective tool to control the outbreak.
The UN has trained and deployed rapid response teams, as well as delivering 22 metric tons of medical and cholera supplies to Renk, Malakal, Juba, and Bentiu.
Risk communication and community engagement include radio broadcasts and household visits. Water supply and sanitation provision is being made safer with water purification tablets, oral rehydration solutions, and soap.
The UN is supporting partners in setting up treatment facilities and rehydration points.
