Machupo hemorrhagic fever
Clinical Classification Guidelines
Inclusion Terms
- Bolivian hemorrhagic fever
Medical Intelligence & Overview
Machupo hemorrhagic fever, also known as Bolivian hemorrhagic fever, is a rare but serious viral disease caused by the Machupo virus. This illness is primarily transmitted in Bolivia and can lead to severe symptoms affecting multiple organ systems. Recognized under the ICD-10 code A96.1, Machupo hemorrhagic fever belongs to a group of diseases known as arenavirus infections, which are primarily spread through contact with certain rodents or their secretions. Early recognition and understanding of this disease are crucial for managing and preventing its spread.
Causes & Symptoms
Clinical Causes: Transmission through contact with rodent excreta, particularly from the Calomys callosus species, a type of rodent native to Bolivia. Exposure to environments contaminated with infected rodent droppings, urine, or saliva. In some cases, person-to-person transmission may occur through exposure to bodily fluids of an infected individual, though this is less common. Infection generally results from activities such as farming, handling contaminated materials, or residing in areas with high rodent populations. No evidence suggests transmission through food or insect bites.
Key Symptoms: Fever, sudden onset Muscle aches and weakness Headache and dizziness Sore throat and cough Nausea, vomiting, and abdominal pain Bleeding tendencies, such as bleeding gums or blood in vomit or stool Reddish spots on the skin (petechiae) Swelling of the face and extremities Potential neurological symptoms, including confusion or seizures in severe cases
Diagnostic & Treatment
Diagnosis Path: Serologic tests to identify viral antibodies Polymerase chain reaction (PCR) testing to detect viral RNA Complete blood count (CBC) to assess for low platelet counts and other abnormalities Liver and kidney function tests to evaluate organ involvement
Treatment Protocols: Maintaining hydration with fluids Monitoring and managing bleeding complications Providing oxygen therapy if respiratory problems arise Treating secondary bacterial infections if they occur Hospitalization in specialized units for severe cases
