Understanding Andes Virus
Origin
Andes virus (ANDV) is a hantavirus endemic to South America, first identified in Argentina in 1995. It is the only hantavirus with documented human-to-human transmission.
Transmission
Primarily via contact with rodent excreta (long-tailed pygmy rice rat, Oligoryzomys longicaudatus). Person-to-person spread is rare but documented — a key driver of this outbreak.
Incubation
4 to 42 days, typically 2-4 weeks after exposure. This wide window complicates contact tracing and preventive isolation.
Symptoms
Hantavirus pulmonary syndrome: fever, myalgia, fatigue, progressing to cough, dyspnea, and pulmonary edema. Severe CFR ≈ 38%.
Treatment
No specific antiviral. Supportive care: mechanical ventilation, hemodynamic support. Early ECMO shows ~80% survival in severe cases.
Prevention
Avoid rodents and their habitats. Healthcare workers: enhanced PPE (N95, gown, gloves, eye protection). No licensed vaccine to date.
