Cholera outbreak in multiple countries

Cholera outbreaks 2025

Since 1 January, 565,404 cholera cases and 7,074 deaths were reported across 32 countries. Countries with the highest transmission of the disease are:

Sudan: Authorities recorded more than 120,000 cases and 3,300 deaths since July 2024. Tawila in Darfur region is heavily-affected. The outbreak is exacerbated by the ongoing civil war, with around 80 percent of health facilities becoming non-functional

South Sudan: Authorities reported at least 95,450 cases and 1,587 deaths since 1 January. The worst-affected areas include Unity, Jonglei and Central Equatorial states..

Yemen: Authorities recorded 87,566 cases and 237 deaths since 1 January. The worst-affected areas are Al Hudaydah, Ta’izz and Ibb governorates, where the population is densely concentrated and healthcare facilities are overwhelmed.

Angola: Authorities recorded 33,146 cases and 859 deaths since 1 January. A third of the cases have been reported in Luanda province.

Other heavily affected countries include the Democratic Republic of Congo (DRC), Afghanistan, Chad, Congo-Brazzaville, Ethiopia, Mozambique, Nepal, Bangladesh, Somalia and Myanmar. All these areas are reporting high transmission and case fatality rates. Fragile healthcare systems, conflict, displacement and natural disasters exacerbate the impact, with WHO assessing the global risk as high.

What to Expect: 

Healthcare infrastructure in heavily affected countries is likely to be poor with a lack of qualified medical professionals, particularly in rural areas where limited access to care delays treatments for affected patients. Conflict, mass displacement and natural disasters threaten fragile communities at risk of cholera or where an outbreak is ongoing.

 

Travel

Impact to Travel:

There are currently no travel restrictions for countries affected by cholera. However, travellers from these areas may face enhanced health screenings. Surveillance measures remain in place at certain airports and borders, including Madagascar, Myanmar, DRC and Gabon.

Advice: 

Travellers should be vaccinated against cholera, consult a medical professional if symptoms occur and ensure water and local produce are properly sanitised. Boiling water for at least one minute is recommended to kill the bacteria.
