Overview
Chapare hemorrhagic fever (also called Chapare virus disease) is a rare and serious viral illness caused by the Chapare virus, which belongs to a family of viruses called arenaviruses. This disease was first identified in 2004 in the Chapare region of Bolivia, South America. Like other hemorrhagic fevers, it attacks the body's ability to control bleeding and can damage multiple organs at the same time. The virus spreads to people mainly through contact with infected rodents or their droppings, urine, or saliva. There is also evidence that the virus can spread from person to person, especially in healthcare settings where protective equipment may not be fully available. This makes it a concern not just for people living in rural areas near rodents, but also for healthcare workers caring for sick patients. Symptoms usually start within one to two weeks of exposure and can include fever, headache, muscle pain, vomiting, and in severe cases, bleeding from the gums, nose, or other parts of the body. The illness can become life-threatening quickly. There are no approved vaccines or specific antiviral drugs for Chapare hemorrhagic fever at this time. Treatment focuses on supportive care, such as managing fluids, controlling bleeding, and treating complications as they arise. Early medical attention is critical for survival.
