125,000 cases, and a disease we have known how to treat since 1832
What happened
The Democratic Republic of the Congo is living through its worst cholera outbreak in twenty-five years, and the figures published this week show it getting worse rather than better. On 14 October 2026, UN News reported World Health Organization data for the country. Since January 2025, the DRC has recorded more than 125,000 suspected cholera cases and 3,644 suspected deaths. In 2026 alone, there have been more than 51,412 suspected cases and 1,487 deaths, spread across 21 provinces. The most recent week counted in that data, 21 to 28 September, recorded 2,932 suspected cases, up from 2,506 the week before. Deaths in that week rose by roughly 39 per cent. Three provinces account for nearly 60 per cent of the suspected cases: South Kivu, North Kivu and Haut-Katanga. UNICEF has described the outbreak as the country's worst in 25 years. All of this is happening while the same country fights a large Ebola outbreak. WHO data cited this week put that at 9,066 cases and 4,381 deaths across seven provinces and 65 health zones. Cholera response teams have been unable to reach some affected areas because of violence, including around Kibua and Masisi. Reactive vaccination campaigns are running in the Mulungu and Shabunda health zones of South Kivu, and preparations are under way for an oral vaccination campaign on islands along the Congo River corridor. The DRC and the Republic of Congo are developing a joint cross-border plan.
Why this matters
Cholera is not a mysterious disease. It is a bacterial infection of the gut, spread through water and food contaminated with faeces. It causes sudden, enormous watery diarrhoea, and it kills by dehydration. An adult can lose several litres of fluid in a few hours. We have known how to treat it since the nineteenth century. Replace the fluid and the salts, fast. Oral rehydration solution costs pennies. Where treatment is available quickly, the death rate can be kept below one per cent. So a cholera death is almost always a logistics failure rather than a medical mystery. It means clean water was not there, or a treatment centre was too far away, or a road was blocked, or fighting stopped a team getting through. That is what makes these numbers so hard to read. 3,644 deaths from a disease with a cheap, well-understood treatment is not a scientific problem. It is a problem of access. There is a second reason to pay attention. Cholera is a marker of broken water and sanitation systems, and those systems break for reasons that spread: conflict, displacement, flooding. When a cholera outbreak grows across 21 provinces, it tells you something about the state of everything around it.
What the evidence actually says
A few points of care are needed with these figures. They are suspected cases, not laboratory-confirmed ones. In a large outbreak, most cases are counted on symptoms because testing every patient is neither practical nor necessary for treatment. That means the figures are useful for tracking a trend but should not be quoted as confirmed infections. The two headline numbers cover different periods, and they are easy to mix up. The 3,644 deaths are cumulative since January 2025. The 1,487 deaths are 2026 only. Both come from WHO data. The weekly figures run to 28 September, so there is a reporting lag. The situation on the ground in mid-October may be better or worse than the last complete week shows. Undercounting is likely rather than possible. In areas teams cannot reach, cases are not counted at all. The real total is probably higher than the reported one. On vaccination, the evidence in the public reporting is thinner than on cases. Reactive campaigns are confirmed in two health zones of South Kivu, and plans exist for the Congo River islands, but no national vaccination totals appear in the sources. Global oral cholera vaccine supply has been under strain for several years, which limits what any country can do quickly. What is not in doubt is the direction. Cases rose week on week, deaths rose sharply, and access is restricted in parts of the worst-affected provinces.
Practical advice
For almost everyone reading this in the UK, the risk of cholera is very low. It is not spread person to person in the way a cold is, and British water and sewage systems do the heavy lifting. There are still a few things worth knowing. If you are travelling to an affected area, check the advice before you book, not after. GOV.UK travel advice and the Travel Health Pro website both carry country-by-country guidance, and both get updated when outbreaks change. Your travel insurance can be affected by official advice, so it is worth a look either way. An oral cholera vaccine exists and is available privately in the UK. It is usually recommended for aid workers, people going to outbreak areas, or those travelling somewhere remote where medical help would be hours away. A travel clinic or your pharmacist can advise whether it is sensible for your trip. It is not routinely needed for an ordinary holiday. The basics still do most of the work. Drink water you trust, from a sealed bottle or boiled. Avoid ice of unknown origin. Eat food that is hot and freshly cooked. Peel fruit yourself. Wash hands with soap, and carry sanitiser for when there is no sink. Know what severe dehydration looks like, in any country. Sunken eyes, very little or no urine, dizziness when standing, a dry mouth, and in children unusual sleepiness or no tears when crying. Severe watery diarrhoea with these signs needs urgent medical help, not a wait-and-see. Oral rehydration sachets are cheap, light and worth packing. Your pharmacy sells them. They are useful for any cause of diarrhoea, not just cholera.
What to know
WHO data reported on 14 October 2026 show the Democratic Republic of the Congo has recorded more than 125,000 suspected cholera cases and 3,644 suspected deaths since January 2025. In 2026 alone there have been more than 51,412 suspected cases and 1,487 deaths across 21 provinces. UNICEF has called it the country's worst cholera outbreak in 25 years. In the week of 21 to 28 September, cases rose to 2,932 from 2,506, and deaths rose by around 39 per cent. South Kivu, North Kivu and Haut-Katanga account for nearly 60 per cent of suspected cases. Violence has blocked access to some areas, including Kibua and Masisi. A separate Ebola outbreak in the same country stood at 9,066 cases and 4,381 deaths. Cholera is treatable with rapid fluid replacement. Where that is available, the death rate can be held below one per cent. For UK travellers, the practical steps are safe water, hot freshly cooked food, handwashing, oral rehydration sachets in the bag, and checking official travel advice before booking.
