Material Proximities and Hotspots: Toward an Anthropology of Viral Hemorrhagic Fevers

This resource outlines a research program for an anthropology of viral hemorrhagic fevers and reviews the social science literature on Ebola, Marburg, and Lassa fevers and charts areas for future ethnographic attention. The paper suggests that attention to the material proximities between animals, humans, and objects, that constitute the "hotspot", opens a frontier for critical and methodological development in medical anthropology and for future collaborations in viral hemorrhagic fever management and control.

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

This resource presents evidence for an expanded endemicity zone between the two known Lassa endemic regions indicating that Lassa virus is more widely distributed throughout the Tropical Wooded Savanna ecozone in West Africa.

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.

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.
