Lassa virus is a RNA virus belonging to the family of Arenaviridae. It was discovered as the causative agent of a hemorrhagic fever--Lassa fever--about 30 years ago. Lassa fever is endemic in West Africa and is estimated to affect some 100,000 people annually. Great progress in the understanding of the life cycle of arenaviruses, including Lassa virus,

In a pattern repeated across a range of ecological niches, arenaviruses have evolved a compact four-gene genome to orchestrate a complex life cycle in a narrow range of susceptible hosts. A number of mammalian arenaviruses cross-infect humans, often causing a life-threatening viral hemorrhagic fever.

Lassa Fever (LF) is a viral hemorrhagic fever endemic in West Africa. LF begins with flu-like symptoms that are difficult to distinguish from other common endemic diseases such as malaria, dengue, and yellow fever making it hard to diagnose clinically.

Individuals living in endemic hotspots of Lassa fever have recurrent exposure to Lassa virus (LASV) via spillover from the primary host reservoir Mastomys natalensis. Despite M. natalensis being broadly distributed across sub-Saharan Africa, Lassa fever is only found in West Africa. In recent years, new LASV reservoirs have been identified.

Plasmid-Based Lassa Virus Reverse Genetics
2023Several mammarenaviruses cause hemorrhagic fever (HF) disease in humans and pose a significant public health problem in their endemic regions. The Old World (OW) mammarenavirus Lassa virus (LASV) is estimated to infect several hundred thousand people yearly in West Africa, resulting in high numbers of Lassa fever (LF) cases, a disease associated with ...

Arenaviruses other than Lassa virus
Antiviral Research, 2003The family Arenaviridae includes 23 viral species, of which 5 can cause viral hemorrhagic fevers with a case fatality rate of about 20%. These five viruses are Junin, Machupo, Guanarito, Sabia and Lassa virus, the manipulation of which requires biosafety level 4 facilities. They are included in the Category A Pathogen List established by the Center for

Lassa Virus Structural Biology and Replication
2023Lassa virus (LASV) is the causative agent of Lassa fever, an often-fatal hemorrhagic fever that is endemic in West Africa. LASV virions are enveloped and contain two single-stranded RNA genome segments. Both segments are ambisense and encode two proteins. The nucleoprotein associates with viral RNAs forming ribonucleoprotein complexes. The glycoprotein

Animal models for Lassa virus infection
Current Opinion in Virology, 2019In humans, Lassa virus infection can result in disease with hemorrhagic manifestations and high fatality rates. There are no approved treatments or vaccines available and the inherent danger of studying Lassa virus means it can only be studied in high containment labs (BSL4).
