Abstract:Lassa virus (LASV) outbreaks in West Africa pose a significant public health threat. We investigated the infection phenotype and transmission (horizontal and vertical) of LASV strain Ba366 in its natural host, Mastomys natalensis. Here we analyze viral RNA levels in body fluids, virus titers in organs and antibody presence in blood. In adults and 2-week-old animals, LASV causes transient infections with subsequent seroconversion. However, mice younger than two weeks exhibit persistent infections lasting up to … Show more
