Lassa fever virus. Coloured transmission electron micrograph (TEM) of a single Lassa virus, cause of Lassa fever. It contains RNA (ribonucleic acid) genetic material and belongs to the Arenavirus group of viruses. Ribosome-like particles can be seen within the central dark green region of the virus. On the surface are proteins, enabling the virus to attach to host cells. Lassa fever occurs in West Africa. Rats harbour the virus which is spread by inhaling rat urine, or coughed droplets of infected patients. High fever, headache and severe muscular pain result, and death may occur due to heart or kidney failure. Antiviral drugs may be of assistance. Magnification unknown.
