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.

At home with Mastomys and Rattus: Human-rodent interactions and potential for primary transmission of Lassa virus in domestic spaces

In this study housing characteristics and domestic organization were fund to have an impact on the direct and indirect, intentional and unintentional contact with rodents indoors. More research on housing and environmental modification, as well as food storage are important for prevention against LASV transmission.

Poor housing quality increases risk of rodent infestation and Lassa fever in refugee camps of Sierra Leone

To determine risk of Lassa fever in households in Sierra Leonean refugee camps, this paper analysed the spatial relationships between households with a Lassa case and focal locations of potential rodent habitats. Quality and hygiene factors of households were assessed to determine possible risk factors for household rodent infestation and occurrence of Lassa fever.

Participation of women and children in hunting activities in Sierra Leone and implications for control of zoonotic infections

This paper underscores the challenges of interventions, surveillance, research and sensitization campaigns. To address such complexity, intervention strategies should become more diversified and context-specific. In particular the role of children should be recognised; specific intervention strategies should be tailored to children's specific hunting practices.

Rat-Atouille: A mixed method study to characterize rodent hunting and consumption in the context of Lassa fever

This paper investigated the consumption of rodents, including the reservoir species of Lassa fever, and found this is widespread and does not neatly tally against generational or gender lines. Further, it found that the reasons for rodent consumption are multifactorial, including taste preferences, food security, and opportunistic behaviour.
