Lassa fever virus particles. Coloured transmission electron micrograph (TEM) of single Lassa virus particles, the cause of Lassa fever. They contain RNA (ribonucleic acid) genetic material and belong to the Arenavirus group of viruses. On the particles' surfaces are proteins that enable 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 from infected patients. High fever, headache and severe muscular pain result, and death may occur due to heart or kidney failure.
