Arenaviridae

Arenaviridae is a family of viruses that primarily spread through rodent hosts. These viruses can infect humans, often causing illnesses such as Lassa fever and Machupo hemorrhagic fever. They are mostly transmitted through contact with rodent droppings, urine, or bites. Arenaviruses have a segmented RNA structure, which allows for genetic variation. While some infections can be mild, others can be severe or deadly. They are considered important in global health due to their potential to cause outbreaks, especially in regions with poor sanitation and close human-rodent interactions.
