The arenaviridae are a family of viruses whose members are generally associated with rodent-transmitted disease in humans. Each virus usually is associated with a particular rodent host species in which it is maintained. Arenavirus infections are relatively common in humans in some areas of the world and can cause severe illnesses.

The list of signs and symptoms mentioned in various sources for arenaviruses includes the 6 symptoms listed below:

a. Malaise

b. Fatigue

c. Fever

d. Weight loss

e. Abdominal pain

f. Night sweats
The primary cause of arenaviruses is the result of transmission of an infectious agent by another person by one or more of the following: saliva, air, cough, fecal-oral route, surfaces, blood, needles, blood transfusions, sexual contact, mother to fetus, etc.
Some Arenaviruses, such as Lassa, Machupo, and Lujo viruses, are associated with secondary person-to-person and nosocomial transmission. This occurs when a person infected by exposure to the virus from the rodent host spreads the virus to other humans. This may occur in a variety of ways. Person-to-person transmission is associated with direct contact with the blood or other body fluids, containing virus particles, of infected individuals. Airborne transmission has also been reported in connection with certain viruses. Contact with objects contaminated with these materials, such as medical equipment, is also associated with transmission. In these situations, use of protective clothing and disinfection procedures help prevent further spread of illness.
