Background

  • Also known as macacine herpesvirus 1, macacine alphaherpesvirus 1, cercopithecine herpesvirus 1, CHV-1), herpes B virus, monkey B virus, herpesvirus simiae and herpesvirus B

History

  • First diagnosed in a researcher in 1933

Microbiology

  • Double-stranded DNA virus
  • Alphaherpesvirus, in the same family as HSV

Pathophysiology

  • Virus replicates locally at the site of inoculation, then spreads from peripheral nerves to spinal cord to brainstem to brain

Clinical Presentation

  • Typically via bite or scratch of macaque monkey
    • Asymptomatic or similar presentation to HSV in the monkey
    • Seroprevalence reaches 100% in some populations of macaques
  • Incubation period 5 to 21 days (range 2 days to 5 weeks)
  • Three clinical forms:
    • Flu-like illness followed by CNS symptoms
    • Local symptoms (itching, tingling, numbness, or pain) at the inoculation site, with or without vesicular rash and regional lymphadenopathy
    • Peripheral or central nervous system symptoms, with meningismus, vomiting, confusion, cranial nerve palsies
  • Eventually progresses to global encephalitis, seizures, paralysis, and respiratory failure
  • Mortality 70% if untreated

Management
