Bolivian hemorrhagic fever
a febrile illness caused by an arenavirus, generally transmitted by contact with or inhalation of aerosolized rodent urine. Person-to-person infection has been documented, but it is very rare. After an incubation period of 1 to 2 weeks, the patient experiences chills, fever, headache, muscle ache, anorexia, nausea, and vomiting. As the disease progresses, hypotension, dehydration, bradycardia, pulmonary edema, and internal hemorrhage may occur. The mortality rate may reach 30%; pulmonary edema is the most common cause of death. There is no specific therapy. Peritoneal dialysis is sometimes performed. Also called Machupo.
