Sub-Saharan Africa is home to a variety of pathogens, however disease surveillance and the healthcare infrastructure necessary for proper management and control are limited. Lassa virus occurs in the West African region, and causes Lassa fever, a severe hemorrhagic fever in humans. At the Kenema Government Hospital in Sierra Leone up to 70 of acute patient samples suspected of Lassa fever test negative for Lassa virus infection, and can be attributed in part to an array of hemorrhagic fever and arthropod-borne viruses. This indicates a substantial amount of disease in the region goes undetected and untreated.
