Argentine Hemorrhagic Fever (AHF) is a viral disease caused by the Junin virus, which is primarily transmitted to humans through contact with infected rodents, particularly the Calomys musculinus species. The disease is endemic to certain regions of Argentina, where outbreaks can occur, especially in rural areas. Symptoms of AHF typically appear 1 to 3 weeks after exposure and may include fever, headache, muscle pain, and gastrointestinal issues. In severe cases, it can lead to bleeding, shock, and even death. Vaccination and early treatment with antiviral medications can help manage the disease and reduce mortality rates.
