The NCDC said to enhance state and international level coordination of all control and management efforts, the Ondo state ministry of health has begun contact tracing.
The NCDC said all necessary in-country structures have been mobilised to ensure all possible contacts are traced and monitored, and information has been shared with all relevant authorities in line with the International Health Regulations (2005), with contact tracing efforts also ongoing in the UK.
The NCDC added that as of March 2, 2025, 2,728 suspected cases, 535 confirmed cases, and 98 deaths have been recorded across 14 states in Nigeria, with a case fatality rate of 18.3 percent.
Five states account for 91 percent of confirmed cases: Ondo (31 percent), Bauchi (24 percent), Edo (17 percent), Taraba (16 percent), and Ebonyi (3 percent).
“Ten local government areas make up 68 per cent of confirmed cases, namely: Owo, Akure South, Etsako West, Kirfi, Akoko South-West, Bali, Esan North-East, Bauchi, Toro, and Jalingo,” the NCDC said in its situation report.
Lassa fever is a zoonotic disease, meaning that humans become infected from contact with infected animals, which are mainly rats.
