Lassa fever, also known as Lassa hemorrhagic fever (LHF), is a type of viral hemorrhagic fever caused by the Lassa virus. Many of those infected by the virus do not develop symptoms. When symptoms occur they typically include fever, weakness, headaches, vomiting, and muscle pains. Less commonly there may be bleeding from the mouth or gastrointestinal tract. The risk of death once infected is about one percent and frequently occurs within two weeks of the onset of symptoms. Of those who survive, about a quarter have hearing loss, which improves within three months in about half of these cases.

Phylogentically the Awash multimammate mouse is the sister taxon of the Natal multimammate mouse, a species found almost everywhere in Africa south of the Sahara and considered a serious agricultural pest throughout its range.
Mastomys is a genus of rodent in the family Muridae endemic to Africa. It contains these species:
The southern multimammate mouse or southern African mastomys is a species of rodent in the family Muridae which is endemic to southern Africa. It is called a multimammate mouse because it can have 8 to 12 pairs of mammae, in comparison other mouse species only have 5 pairs.

A robovirus is a zoonotic virus that is transmitted by a rodent vector.
Morogoro virus is an East African arenavirus infecting the multimammate mouse. The virus is genetically closely related to Lassa virus, known to cause Lassa fever in humans. Morogoro virus, however, does not seem to infect humans. Transmission of Morogoro virus between mice is assumed to occur via direct and indirect contact. Infected animals pass a latent period of 7 days and subsequently shed the virus for about 30 days, after which they recover and develop lifelong antibodies. Transmission may also be possible from infected mothers to offspring and through sexual contact, as this has been suggested for other arenaviruses.
Praomyini is a tribe of muroid rodents in the subfamily Murinae. Species in this tribe are found mostly throughout Sub-Saharan Africa, but one species is found in North Africa, and another is found in the Arabian Peninsula. In addition, one fossil genus (Karnimata) is known, which inhabited India and Pakistan during the Late Miocene.
