Kenya’s cholera risk in 2026 sits at the point where weather, displacement and weak water systems meet, and NGOs running water, sanitation and hygiene (WASH) programmes are the first line of defence. The most recent figures from the World Health Organization show a small outbreak centred on the Dadaab refugee complex in Garissa County, with 40 cumulative cases and one death by mid-July 2026. It was contained. The short rains now due in October and November are the test of whether the lessons stuck.
What is the cholera situation in Kenya in 2026?
WHO’s regional weekly situation report for epidemiological week 28 (5 to 12 July 2026) records 40 cumulative cases and one death in Kenya, a case fatality rate of 2.5 per cent. Garissa County accounted for 39 of the cases, all linked to Dagahaley camp in Dadaab sub-county. Nairobi had one case, in Ruaraka sub-county.
By the report’s own account the outbreak was controlled in Nairobi, with more than 28 days since its last case, and Garissa had gone 27 days without a new case. Children under five made up 37.5 per cent of cases, and 20 per cent were under two. The report notes small inconsistencies between its headline total and its demographic table, so treat the numbers as indicative rather than final. We could not find a later WHO report with updated figures as of 13 October 2026, so check the Ministry of Health and WHO before quoting current counts.

Why does 2025 still matter for 2026 planning?
Because it shows how fast a few cases become a national problem. According to Ministry of Health data reported by the Eastleigh Voice, Kenya had 379 cases and 18 deaths by 17 June 2025. The first case was recorded on 12 February 2025 in Kuria East, Migori County, and the outbreak went on to reach Kisumu, Turkana, Nairobi, Kwale and Mombasa. Kisumu carried the heaviest toll with 99 cases and 7 deaths, while Mombasa’s cases clustered in the Kibarani settlement.
The response then relied heavily on simple WASH measures: Aqua tabs and chlorine for household water treatment, super-chlorination of communal water sources in Kisumu and Nairobi, and household disinfection and hygiene promotion in Kwale. Those are tasks NGOs and community health promoters already do.
Why are the short rains a cholera risk?
Heavy rain and flooding push sewage into shallow wells, rivers and open drains, and they cut off roads that carry treatment supplies. Our earlier guide on how Kenyan NGOs should prepare for El Niño in 2026 covers the wider flood picture, and the new anticipatory action guide explains how forecast-triggered funding can be used before the rains arrive. Cholera is one of the most predictable consequences, which makes it one of the best candidates for early action.
What should an NGO WASH programme do before the rains?
- Map water sources and sanitation gaps in the settlements you serve, starting with informal areas, camps and flood-prone riverbanks.
- Preposition supplies such as chlorine, water treatment tablets, oral rehydration salts, soap and covered storage containers, so stock is not stranded when roads flood.
- Train community health promoters to recognise acute watery diarrhoea, start oral rehydration at once and refer early.
- Agree referral routes with the nearest health facility and the county public health team before an alert, not after it.
- Plan hygiene messaging around handwashing, safe water storage and food safety, and monitor rumours about unsafe water or home remedies, as WHO’s report highlights.
- Protect dignity in death and burial: WHO supported updated procedures for safe and dignified burials in the 2026 response.
What does the Ministry of Health tell the public?
During the 2025 outbreak the Ministry advised people to drink only boiled or chlorinated water, store it in clean covered containers, use functional latrines, wash hands before preparing food and start oral rehydration solution at the first sign of diarrhoea. It warned against self-medication and traditional remedies. Build the same messages into your community sessions, in local languages. For wider WASH programming and funding, see our guide to WASH NGOs in Kenya in 2026.
How can an NGO coordinate with the official response?
Register your activities with the county health department, share data on suspected cases through the proper channels, and align your messaging with Ministry guidance. In refugee settings, coordinate through the camp-level health and WASH sectors. Parallel responses that bypass county teams tend to duplicate effort and confuse communities. The latest regional situation data is published by WHO’s Regional Office for Africa (week 28 report, July 2026).
Frequently asked questions
Is there a cholera outbreak in Kenya right now?
The latest WHO report we could verify, covering 5 to 12 July 2026, described the Garissa and Nairobi outbreaks as controlled. We could not confirm newer figures as of 13 October 2026, so check the Ministry of Health for current status.
How many cholera cases did Kenya record in 2026?
WHO reported 40 cumulative cases and one death as of mid-July 2026, almost all in Dadaab’s Dagahaley camp.
What are the symptoms of cholera?
Profuse watery diarrhoea, vomiting and abdominal cramps. Anyone with these symptoms should start oral rehydration solution and seek care promptly.
How can NGOs help prevent cholera?
By securing safe water, preparing supplies ahead of the rains, training community health promoters, promoting handwashing and safe storage, and working alongside county health teams.
Where do NGOs report suspected cholera cases?
To the nearest health facility and the county public health office, which notify the national surveillance system. Do not run a separate reporting channel.
Figures are drawn from WHO AFRO’s week 28 situation report (July 2026), the Eastleigh Voice’s June 2025 report of Ministry of Health data, and The Standard’s 2025 reporting of Ministry guidance; confirm current numbers with official sources.
