The UK Health Security Agency has issued a stark warning following a significant rise in cholera cases among travellers returning to the United Kingdom from four specific destinations. Newly released data for 2025 reveals a troubling 56 per cent increase in confirmed infections, highlighting growing concerns over this acute diarrhoeal disease that can prove fatal within hours if left untreated.
Sharp Increase in Travel-Associated Cholera Infections
According to the UKHSA report, there were 14 confirmed cholera cases in England, Wales, and Northern Ireland during 2025. This marks a substantial jump from the nine cases reported in the previous year. Among these infections, thirteen were directly linked to international travel, while one individual contracted the illness after consuming water imported from an endemic country.
Primary Travel Destinations Identified
The agency has pinpointed four main destinations where travellers likely acquired the infection:
- India – 4 cases
- Pakistan – 4 cases
- Ethiopia – 3 cases
- Rwanda – 1 case
One additional case did not have a specified travel history. Cholera remains endemic in Pakistan and parts of India, where thousands of cases were reported in 2025. Ethiopia is experiencing an ongoing outbreak that began in 2022, with over 58,000 cases recorded by early 2025.
Understanding Cholera: Symptoms and Transmission
Cholera is an acute, severe diarrhoeal infection caused by ingesting food or water contaminated with the bacterium Vibrio cholerae. The disease spreads primarily through the faecal-oral route via contaminated water supplies, ice, or food, rather than direct person-to-person contact.
Rapid Onset of Symptoms
Symptoms can manifest within a few hours to five days after exposure. They typically include:
- Sudden onset of severe, painless, watery diarrhoea often described as 'rice water stools'
- Persistent vomiting
- Rapid dehydration that can lead to shock
While many cases present with mild symptoms, the infection can cause such rapid fluid loss that it becomes fatal within hours without proper medical intervention and rehydration treatment.
Global Cholera Context and UK Implications
The World Health Organization has reported a global increase in cholera notifications in recent years. In 2024, 39 countries reported outbreaks, with 21 countries documenting travel-associated cases only. By 2025, cases were reported across 33 countries spanning five WHO regions, with the highest numbers in the Eastern Mediterranean, followed by Africa, South-East Asia, the Americas, and the Western Pacific.
Prevention and Vaccination Considerations
The UKHSA emphasises that cholera thrives in areas with inadequate sanitation and contaminated water systems. While a vaccine is available, it is only recommended for certain travellers to high-risk regions rather than as a routine precaution for all international visitors.
Public health officials urge travellers to exercise extreme caution with food and water consumption when visiting cholera-endemic regions. Proper hygiene practices, avoiding untreated water, and consuming only thoroughly cooked foods can significantly reduce infection risk. The agency continues to monitor the situation closely as international travel patterns evolve.
