At least 40 people died in the latest outbreak of Lassa fever in Nigeria, four of them health workers. The Nigeria Centre for Disease Control (NCDC) said this on its website today, February 6.
The disease control agency said it is currently distributing medical response commodities to states and treatment centres.
Lassa fever is a viral haemorrhagic fever transmitted by rats. It has been known since the 1950s, but the virus was not identified until 1969, when two missionary nurses died from it in the town of Lassa in Borno State.
Found predominantly in West Africa, it has the potential to cause tens of thousands of deaths. Even after recovery, the virus remains in body fluids, including semen.

Neighboring countries are also at risk, as the animal vector for Lassa virus, the “multimammate rat” (Mastomys natalensis) is distributed throughout the region.
