Cumulative infections increased from 1,021 in week 32 to 1,035 in week 33, while deaths rose from 240 to 252.

The case fatality rate also increased to 24.4 percent, compared with 23.5 percent in week 32 and 18.6 per cent recorded in 2025.
“The 14 new cases represented an increase from four cases reported during epidemiological week 32, when cases were recorded in Ondo and Edo states,” the NCDC said.
The agency said 23 states had reported at least one confirmed case across 117 local government areas by week 33.
Bauchi, Ondo, Taraba, Benue and Edo accounted for 87 per cent of cumulative confirmed cases.
The five states also accounted for 86 per cent of confirmed cases recorded in week 32, remaining the most affected states.
