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[1]
- 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
- Consider rabies prophylaxis for all
Asymptomatic Prophylaxis (Acute Exposure)
- <20 minutes clean and irrigate
- Antiviral prophylaxis
- 14 day course of PO valacyclovir 1gm three times daily OR
- 14 day course of PO acyclovir 800mg five times daily[2]
- Indications
- Penetrating (especially head, neck, torso)
- Fluid on mucosa
- Blistering Monkey
All non-CNS symptomatic
- Admit and treat
- Antiviral
- Acyclovir IV 12.5-15 mg/kg every eight hours OR
- Ganciclovir IV 5mg/kg every 12 hours[2]
All CNS Symptomatic
- Admit and treat
- Ganciclovir IV 5mg/kg every 12 hours[2]
Disposition
- Asymptomatic Discharge
- Symptomatic Admit
