NCDC records 65,000 cholera cases and 10,000 diphtheria infections this year

Nigeria has recorded more than 65,000 suspected cholera cases in 2026 across 35 states and about 195 local government areas, NCDC Director-General Jide Idris said in Abuja on Friday. Confirmed diphtheria cases have passed 10,000 and remain concentrated in Kano, Borno and Bauchi.

Idris told a press briefing that weekly cholera numbers have fallen well below the peak recorded earlier in the season. The share of cases that end in death is also lower than at the same point last year. He asked the country not to treat that improvement as an ending. Cholera in Nigeria often climbs again between late August and October. The rains are still falling. Floods contaminate wells and overwhelm latrines.

Borno accounts for most of this year's cholera caseload. Idris said outcomes improved where treatment was moved closer to the people who needed it. Early access, not a change in the bacterium, is the reason fewer patients are dying. The agency is still running oral cholera vaccination, water chlorination, repairs to water points and hygiene campaigns in the worst-hit communities.

Enugu is the exception on the map. Idris said it is the only state that has not reported a cholera case this year. He rejected the suggestion that officials there were hiding infections. The state government, he said, had been proactive. He also warned against reading a blank line on a spreadsheet as proof that sporadic cases cannot appear tomorrow.

The drivers he listed are familiar and still in place: unsafe water, open defecation, broken pipes, weak hygiene in schools and markets. None of those conditions moved on Friday. What moved was the official count and the calendar warning. A 65,000-case year that is already improving can still reverse in six weeks if a flood hits a city that has not chlorinated its tanks.

Diphtheria is a different disease with a tighter geography. Ten thousand confirmed cases in three states point to gaps in routine immunisation rather than to a nationwide water failure. Idris discussed both outbreaks in the same briefing because both are running at once and both punish the same poorly served local government areas. The responses diverge. Cholera needs water and beds close to home. Diphtheria needs vaccines, antitoxin and a cold chain that reaches Kano, Borno and Bauchi without breaks.

NCDC's own recent-year record is why Idris spent so long on the late-season risk. Nigeria has watched cholera curves dip in mid-year and then rise when the rains peak. The 2026 curve is following that shape so far: a high first wave, a decline, a warning. The next sitrep that matters is the weekly case count in September, not the cumulative 65,000 already booked.

For state health commissioners the usable instruction from Friday is narrow. Keep treatment sites open in Borno. Do not stand down chlorination teams because the weekly line bent downward. Treat Enugu's zero as a standard to copy, not as a reason to stop looking. The bacterium does not read briefings. It reads water.
