Chapare hemorrhagic fever and virus detection in rodents in Bolivia in 2019

In 2019, a cluster of cases of Chapare hemorrhagic fever has taken place in the municipality of Caranavi and expanded to La Paz. Four of nine cases of the hemorrhagic fever had died. Probable nosocomial transmission among health  care workers was identified. Chapare virus RNA was detected in a variety of human body fluids including blood, urine, nasopharyngeal, oropharyngeal and bronchoalveolar-lavage fluids, conjunctiva and semen. Viral RNA was also obtained from captured small-eared pygmy rice rats. In survivors of the hemorrhagic fever, viral RNA was detected up to 170 days after symptom onset, and the virus was isolated from a semen sample 86 days after symptom onset
