Machupo virus is a rare viral infection caused by an arenavirus primarily found in parts of South America. It is responsible for Bolivian hemorrhagic fever, a serious illness that can lead to severe complications if not treated promptly.

The virus is mainly transmitted to humans through contact with infected rodents or their droppings, urine, or saliva. People living in rural areas where infected rodents are present have a higher risk of exposure. Early diagnosis and supportive medical care are important for improving recovery and preventing complications.

What Types of Machupo Virus Exist?

Machupo virus is categorized into different genotypes based on genetic variation and geographic distribution.

Genotype A is associated with human infections causing Bolivian hemorrhagic fever
Genotype B is also linked with severe infections in humans
Genotype C is identified mainly in rodents in Venezuela
Genotype D detected in rodents in Argentina
Genotype E a recently identified variant, was reported in Bolivia

What Are the Symptoms of the Machupo Virus?

Symptoms of Machupo virus infection usually appear after an incubation period and may worsen as the disease progresses.

High fever lasting several days
Severe headache
