Fatal Case of Human B Virus Infection Manifesting with Hemorrhagic Encephalitis and Chorioretinitis

Key Points

• To investigate a fatal case of hemorrhagic encephalitis and chorioretinitis caused by the B virus.
• Case report of a patient with prior monkey bites and scratches.
• Detection of B virus gB gene sequence from cerebrospinal fluid (CSF).
• Phylogenetic analysis of the B virus sequence compared to known samples.
• The patient exhibited symptoms of hemorrhagic encephalitis and chorioretinitis.
• B virus gB gene sequence was identified in CSF and clustered with rhesus macaques.
• Phylogenetic analysis confirmed the close relationship between the virus strains.
