Médecins Sans Frontières (MSF) said Bauchi State recorded 68 deaths and 311 confirmed Lassa fever cases between October 1, 2025, and March 23, 2026.
MSF said it has supported treatment since 2022 at the Lassa Fever Centre, offering diagnosis, medication, and mental health care.
Outreach teams also operate in Bauchi, Kirfi, Toro, and Tafawa Balewa LGAs, focusing on early detection, isolation, and referrals.
MSF official Abdulkareem Yakubu said the group is training health workers and tackling misinformation.
Emergency Programme Manager Dr. Ayokunnu Raji noted that symptoms often mimic malaria, delaying treatment.
MSF said Lassa fever spreads through contaminated food or contact with infected fluids. While most cases are mild, severe infections can be fatal.
Nationwide, Nigeria recorded 516 cases and 135 deaths this year, a 31% increase. MSF is responding in six states and plans to upgrade the Bauchi centre into a training hub.
