Lassa fever kills 99 Nigerians in eight weeks. The peak months were always on the calendar.

Nigeria knows when Lassa fever comes.

November to April, every year, the same geography. Five states — Bauchi, Ondo, Taraba, Edo, and Benue — account for 84 percent of confirmed cases. The NCDC publishes weekly situation reports. Maps the spread. Names the hotspots.

In the first eight weeks of 2026, 99 Nigerians died. Nearly 2,000 suspected cases. Twenty-eight healthcare workers infected. Three of them dead.

The NCDC named the causes itself: patients arriving at hospitals too late because treatment costs too much, poor sanitation in high-burden communities, healthcare workers getting infected because infection prevention protocols aren't being enforced at facility level. None of those are new. They appear in last year's situation report. And the year before.

Here's the line buried in the NCDC's call to action this week: it urged state governments to "urgently approve and release outbreak preparedness and response funds."

That sentence is the story. The money exists in principle. States budget for health emergencies. But releasing funds requires a governor's sign-off, and a governor's sign-off requires political priority, and a disease that kills quietly in rural local government areas rarely wins that competition against the things that do.

The Lassa virus spreads through contact with food contaminated by the multimammate rat. You prevent it with clean food storage, proper waste disposal, and early treatment with ribavirin. No medical breakthrough required. Just consistent funding and consistent attention across a full dry season — the two things Nigeria's public health system has never managed to sustain.

Ninety-nine deaths in eight weeks, in a predictable window, in known states. That's not a surprise outbreak. That's a system revealing what it's decided to prioritise.
