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.

Diversity and dynamics in a community of small mammals in coastal Guinea, West Africa

This resource investigated three villages in high endemic zones of Lassa fever in Guinea and presents the biodeiversity of the small mammal community identified through standardized trapping in houses, cultivations and forest.

Forecasting rodent outbreaks in Africa: an ecological basis for Mastomys control in Tanzania

This study collected rainfall data preceding historical outbreaks of Mastomys rats in East Africa in order to test the hypothesis that such outbreaks occur after long dry periods. It found that rodent outbreaks were generally not preceded by long dry period and the population dynamics of Mastomys natalensis rats in Tanzania are significantly affected by the distribution of rainfall during the rainy season.

Perceptions of burden of caregiving by informal caregivers of cancer patients attending University of Calabar Teaching Hospital, Calabar, Nigeria

Though not about Lassa fever specifically, this study shows the burden experienced by informal caregivers of cancer patients in Nigeria. Most caregivers experienced this burden as moderate or severe.

Fluctuation of abundance and Lassa virus prevalence in Mastomys Natalensis in Guinea, West Africa

This study investigates the link between the ecology of the M. Natalensis and the incidence of Lassa fever in human cases in Guinea. They found that the risk for Lassa virus transmission was present in both rainy and dry season; however the risk increased in the dry season because of the possibility of encountering rodent excreta in the houses.

Movement patterns of small rodents in Lassa fever-endemic villages in Guinea

The authors investigate in this study the spatial behaviour of M. Natalensis in Upper Guinea. They use to experiments: capture-mark-recapture studies and Rhodamine B. Their findings showed that M.Natalensis moves between houses and proximate fields. This is an important information for rodent control activities that need to be extended from indoors to fields.

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.
