Data set on Lassa fever in post-conflict Sierra Leone.

Lassa fever is a rodent-borne illness that is endemic to parts of sub-Saharan Africa, including Sierra Leone, Nigeria, and Guinea. The disease is named after the town of Lassa, Nigeria where it was discovered in 1969. This data article focuses on the epidemiology of Lassa fever in Sierra Leone following a decade-long civil war that ended in 2002. The data were collected at Kenema Government Hospital (KGH) in Kenema, Sierra Leone, which maintains the country׳s only Lassa fever treatment facility and a biosafety level 3 (BSL-3) laboratory. The key data set variables include Lassa fever serostatus determined using antigen (Ag), immunoglobulin M (IgM), and immunoglobulin G (IgG) ELISA diagnostic techniques; and patient demographics, survival outcome, and treatment (ribavirin) status. The individual data used to generate the graphs and tables in the corresponding research manuscript published in PLOS Neglected Tropical Diseases in 2014 and its coding guide are provided as Supplementary material (Shaffer et al., 2014) [1].
