    ### Instruction:
    How to diagnose Chapare Hemorrhagic Fever (CHHF) ?
    ### Response:
    CHHF virus has been successfully isolated from both blood and serum during the acute febrile phase of illness. Although not undertaken at the time of the initial cluster, virus can certainly be isolated from tissue obtained post-mortem if available. A subsequent complete genomic analysis of Chapare virus facilitated the development of specific molecular detection (RT-PCR) assays.
