Background

  • Cercopithecine herpesvirus 1 (commonly referred to as B virus)
  • Zoonotic Endemic in Macaque Monkeys-mild symptoms like blisters
  • Fatal Encephalomyelitis in Humans: 80% fetal without treatment
  • Most common transmission by bite, but very few cases
  • Consider in Patients with Exposure, especial penetrating bites, to Macaque Monkeys in the wild or research

Clinical Features

  • Vesicular Herpetic Lesions
  • Nonspecific Flu-like Illness
  • Lymphadenitis
  • Site of inoculation - pain, numbness, itching
  • CNS - poor coordination, respiratory depression
  • Encephalitis - late stage of the disease

Differential Diagnosis

Diagnostic Evaluation

  • Clinical
  • PCR specificity and sensitivity at nearly 100% for serologic
  • PCR wound samples less reliable
  • All symptomatic should be tested

Management

  • Treatment
    • <20 minutes clean and irrigate
  • Prophylaxis:
    • 14 day course of PO Valacyclovir 1gm three times daily
    • 14 day course of PO Acyclovir 800mg five times daily
  • All non-CNS symptomatic: Admit and treat
    • Acyclovir IV 12.5-15 mg/kg every eight hours OR
    • Ganciclovir IV 5mg/kg every 12 hours
  • All CNS Symptomatic Admit and treat
    • ganciclovir IV 5mg/kg every 12 hours

Asymptomatic Prophylaxis

  • Treat if high risk for transmission:
    • Penetrating (especially head, neck, torso)
    • Fluid on mucosa
    • Blistering Monkey

Disposition

  • Asymptomatic Discharge
  • Symptomatic Admit
