Lassa fever is a viral infection caused by the Lassa fever virus. The virus is primarily transmitted to humans via contact with excreta from rats. The disease occurs throughout the year, but more cases are recorded during the dry season.

The Nigeria Centre for Disease Control (NCDC) has intensified its response to the Lassa Fever outbreak as the number of confirmed Lassa Fever cases from January 1 this year rose to 317 as at the 25th of February 2018, crossing the total number of confirmed cases recorded in 2017.

Three states in Nigeria; Edo, Ondo and Ebonyi State carry 85% of the burden of Lassa fever cases currently.

  • A total of 2845 contacts have been identified from 18 active states and 1897 are currently being followed up


  • National Lassa Fever multi-partner multi-agency Emergency Operations Centre (EOC) continues to coordinate the response activities at all levels. The EOC operates on six major pillars: Coordination, Surveillance/Epidemiology, Case management/Infection Prevention and Control/Safe Burial, Risk Communication, Logistics and supplies and Laboratory. Response activities revolve around these pillars. The members of the EOC are drawn from various Ministries including the Ministries of Agriculture and Environment, as well as partner agencies. As the outbreak continues with more states reporting confirmed cases, the NCDC encourages all states to set up state-level EOC for proper and better management of response activities.
  • With the activation of the National Reference Laboratory in Abuja, the testing capacity in Nigeria has increased from two to three laboratories. This is in addition to the Irrua Specialist Teaching Hospital and the Lagos State University Teaching Hospital, which were previously the only two laboratories with the capacity to diagnose Lassa fever.
  • NCDC is collaborating with the Alliance for International Medical Action (ALIMA) and Médecins Sans Frontières (MSF) in Edo, Ondo and Anambra States to support case management
  • NCDC deployed teams to four Benin Republic-border states (Kebbi, Kwara, Niger and Oyo) for enhanced surveillance activities
  • The World Health Organisation (WHO) is scaling up its support of the response at National and State levels.
