Pediatric Lymphocytic Choriomeningitis Virus


Lymphocytic choriomeningitis virus (LCMV) is a single-stranded RNA virus of the family Arenaviridae. Other members of Arenaviridae include Lassa, Argentine hemorrhagic fever, Bolivian hemorrhagic fever, and Venezuelan hemorrhagic fever viruses. LCMV causes an asymptomatic infection in its rodent reservoir (eg, mice) and has variable effect on hamster health. It is passed to humans when they inhale, consume, or otherwise contact infected excreta. Typically a febrile, self-limited, biphasic disease, LCMV is a significant teratogen, whose role in congenital infections has only recently gained appreciation.
Individuals who are exposed to rodents from living conditions or other exposure, such as pet handlers and laboratory personnel, are at particular risk for infection. Transmission of infection during organ transplantation has been documented.
