Chapare virus

Chapare hemorrhagic fever

Chapare mammarenavirus is a virus from the family Arenaviridae and causes hemorrhagic fever (Chapare hemorrhagic fever). An outbreak of Chapare mammarenavirus infection occurred in the village of Samuzabeti, Chapare Province, Bolivia, in January 2003.[2][3][4] A small number of people were infected. One person died. In 2019, two patients transmitted the virus to three healthcare workers in Bolivia’s de facto capital, La Paz. One of the patients and two medical workers later died.[5]The specific transmission vector is not known, but is suspected to be a rodent, in keeping with other members of the arenavirus family, which includes Lassa mammarenavirus.[6]


In December 2003, an outbreak of the Chapare virus occurred near Cochabamba, Bolivia.


The symptoms include: headache, fever, body aches, nose bleeds, and bleeding gums.


No treatment or cure has been discovered yet.
