Lassa fever in West Africa: evidence for an expanded region of endemicity

Zoonoses Public Health. 2012 Sep;59 Suppl 2:43-7. doi: 10.1111/j.1863-2378.2012.01469.x.

Abstract

Lassa virus (LASV) is endemic in Sierra Leone, Guinea and Liberia (known as the Mano River region) and Nigeria and Lassa fever cases from these countries are being reported annually. Recent investigations have found evidence for an expanded endemicity zone between the two known Lassa endemic regions indicating that LASV is more widely distributed throughout the Tropical Wooded Savanna ecozone in West Africa.
