Argentine hemorrhagic fever is a viral disease caused by the Junin virus, primarily transmitted through contact with infected rodents or their droppings. It is endemic to certain regions of Argentina, where outbreaks can occur, especially in rural areas. Symptoms typically include fever, muscle pain, and bleeding, which can lead to severe complications. The disease is part of a group known as hemorrhagic fevers, which are characterized by bleeding and multi-organ involvement. Early diagnosis and supportive care are crucial for improving outcomes. A vaccine is available for high-risk populations, helping to reduce the incidence of the disease in affected areas.
