Lassa fever in post-conflict Sierra Leone

This resource presents observations of case fatality rates of Lassa fever in Sierra Leone after the civil war and compared to studies completed prior to the conflict. Peak presentation of Lassa fever cases occurs in the dry season, which is consistent with previous studies. This paper's studies also confirmed reports conducted prior to the civil war that indicate that infants, children, young adults, and pregnant women are disproportionately impacted by Lassa fever.

Lassa Fever: a rodent-human interaction

This resource examines the sites of interactions between humans and the multimammate mouse, Mastomys natalensis. It presents findings such as new arenaviruses in other African rodents and in snakes, that  argue preferably toward the host-switching concept. The recent emergence in Sierra Leone, the absence of virus positive Mastomys between the two endemic zones and poor virus diversity in the Mano River area also point in the direction of a unique import of Lassa virus from Nigeria to Sierra Leone during the 19th century. This resource also discusses the hypothesis of human displacements through the Atlantic slave trade and its abolition in 1807.

Case-control study of Mastomys natalensis and humans in Lassa virus-infected households in Sierra Leone

This resource studied Lassa virus infection and antibodies in households where Lassa fever cases occurred and compared these to those in the nearest neighbour houses and "far" houses located across the village. It reports on rodent infection and human anti-body prevalence.

Housing equity for health equity: A rights-based approach to the control of Lassa fever in post-war Sierra Leone

This resource focuses on Lassa fever as a matter of human rights, proposing a strategy to improve housing quality, and discusses how housing equity has the potential to improve health equity and ultimately economic productivity in Sierra Leone. The paper is designed to spur discussion and action towards the provision of housing as part of efforts to prevent disease.

Acute sensorineural deafness in Lassa fever

This resource describes a prospective audiometric evaluation of 69 hospitalized febrile patients in Sierra Leone, West Africa, that revealed a sensorineural hearing deficit (SNHD) in 14 (29%) of 49 confirmed cases of Lassa fever and in 0 of 20 febrile controls. This study found that lassa fever is associated with an incidence of SNHD, which considerably exceeds that previously reported with any other postnatally acquired infection.
