Land use gradients drive spatial variation in Lassa fever host communities in the Eastern Province of Sierra Leone. [PDF]

J Anim Ecol
As West Africa urbanises, the risk of Lassa fever may paradoxically decrease. We found the invasive house mouse, a dominant urban species, outcompetes and displaces the primary Lassa virus host. Considering these species interactions is critical for accurately predicting future zoonotic disease patterns.

Partitioning Social and Spatial Drivers of Infection Risk. [PDF]

Ecol Evol
Contact rates drive disease spread, yet are often oversimplified as uniform across individuals. Using data on Mastomys natalensis, we show that exposure to Morogoro virus is linked to spatial overlap with infected conspecifics, but not overall overlap, and that direct contact occurs with only a few individuals despite broad home range overlap ...

Comparison of rodent community between natural and modified habitats in Kafta-Sheraro National Park and its adjoining villages, Ethiopia: implication for conservation

Journal of Basic and Applied Zoology, 2019
Background Distribution and diversity of rodents vary across habitats due to different environmental factors. An ecological comparative study on diversity and abundance of rodents was conducted in Kafta-Sheraro National Park and its nearby villages from ...

Species Composition, Diversity, Abundance, and Phylogeny of Fleas of Small Mammals in Selected Plague-Endemic and Nonendemic Areas of Tanzania. [PDF]

J Parasitol Res
The remerging nature of plague requires detailed understanding of the plague flea vectors and small mammal reservoir interactions. Therefore, this study is aimed at assessing flea vector composition, diversity, prevalence, abundance, and phylogeny in selected villages of Lushoto, Mbulu, and Morogoro Rural districts in Tanzania.

Geographic distribution and genetic characterization of Lassa virus in sub-Saharan Mali. [PDF]

PLoS Neglected Tropical Diseases, 2013
Lassa fever is an acute viral illness characterized by multi-organ failure and hemorrhagic manifestations. Lassa fever is most frequently diagnosed in Nigeria, Sierra Leone, Liberia, and Guinea, although sporadic cases have been recorded in other West ...

Two Novel Arenaviruses Detected in Pygmy Mice, Ghana

Emerging Infectious Diseases, 2013
Two arenaviruses were detected in pygmy mice (Mus spp.) by screening 764 small mammals in Ghana. The Natal multimammate mouse (Mastomys natalensis), the known Lassa virus reservoir, was the dominant indoor rodent species in 4 of 10 sites, and accounted ...

MHC-I alleles mediate clearance and antibody response to the zoonotic Lassa virus in Mastomys rodent reservoirs.

PLoS Neglected Tropical Diseases
West African Mastomys rodents are the primary reservoir of the zoonotic Lassa virus (LASV). The virus causes haemorrhagic Lassa fever and considerable mortality in humans. To date, the role of Mastomys immunogenetics in resistance to, and persistence of,

Sympatric Occurrence of 3 Arenaviruses, Tanzania

Emerging Infectious Diseases, 2010
To determine the specificity of Morogoro virus for its reservoir host, we studied its host range and genetic diversity in Tanzania. We found that 2 rodent species other than Mastomys natalensis mice carry arenaviruses. Analysis of 340 nt of the viral RNA

Mopeia Virus–related Arenavirus in Natal Multimammate Mice, Morogoro, Tanzania

Emerging Infectious Diseases, 2009
A serosurvey involving 2,520 small mammals from Tanzania identified a hot spot of arenavirus circulation in Morogoro. Molecular screening detected a new arenavirus in Natal multimammate mice (Mastomys natalensis), Morogoro virus, related to Mopeia virus.

Views of Health Professionals on the Contribution of Climate Change to the Transmission of Lassa Fever in Nigeria and the Implications for Risk Communication

Advances in Public Health, Volume 2026, Issue 1, 2026.
Lassa fever is an acute viral haemorrhagic illness caused by the Lassa virus and is mainly spread through direct and indirect human–rodent interaction. In Nigeria, Lassa fever outbreaks are becoming more frequent, and studies suggest that changes in climatic and ecological conditions will exacerbate these trends. It is crucial that health professionals
