Introdution: Lassa fever is a viral hemorrhagic disease caused by the Lassa virus, a single stranded RNA virus of the Arenavirus family. It is a zoonotic illness spread by rats of the speciesMastomys natalensis . Between weeks 1 and 17, (2017), 242 suspected Lassa fever cases were reported in Nigeria, with 58 laboratory confirmed cases and 46 fatalities (CFR, 19.01%) from 50 Local Government Areas (LGAs) in 20 States. Methods: We conducted an outbreak investigation and gathered a thorough clinical history of the index case as well as contacts, who were then followed up using the standard viral hemorrhagic fever contact monitoring form. Following that, blood samples were collected from this patient. A total of 54 contacts were tracked for 21 days and their temperatures were recorded using a clinical thermometer. Furthermore, an environmental evaluation of the Zabarmari community and the Madinatu Internally-displaced persons' (IDP) camp was carried out. Results: The index case was a 32-year-old woman who was internallydisplaced in Zabarmari community. Her symptoms began with fever and vaginal bleeding and progressed to bleeding from the nose, mouth, and urethra. There was a history of rat exposure as well as inadequate environmental sanitation and hygiene. Real Time PCR detected Lassa fever in the blood sample. The Borno State Ministry of Environment, in partnership with the Ministry of Health, undertook public health education on Lassa fever prevention and implemented excellent sanitary measures. Conclusion: Increased awareness creation on good infection prevention and control practices is crucial among internally-displaced person and health care providers to prevent occurrence and spread of the disease.
