Multiple Organ Dysfunction Syndrome Caused by Human Herpes Virus 6B Infection in Adults:Report of One Case

Human herpes virus 6 (HHV-6) infection generally occurs in infancy,and the virus is mostly latent in monocytes and macrophages in the peripheral blood.HHV-6 is reactivated when the immune function is suppressed.HHV-6 DNA can be detected in peripheral blood mononuclear cells in more than 80% of healthy adults in China,while the incidence is low in the adults with normal immune functions.This paper reports a case of multiple organ dysfunction syndrome caused by HHV-6B infection in an adult with normal immune functions.High-throughput sequencing revealed the presence of HHV-6B with high confidence in blood and cerebrospinal fluid.
