Rabies Exposure

Infectious Diseases

Post-exposure prophylaxis for bite / scratch from suspect rabid animal.

History taking

  • Onset, duration, progression, severity
  • Aggravating / relieving factors
  • Past history, drugs, allergies, comorbidities
  • Family & social history relevant to presentation

Examination

  • General: vitals, pallor, icterus, oedema, lymphadenopathy
  • Focused system examination
  • Look for red-flag findings

Red flags

  • Haemodynamic instability
  • Rapid deterioration
  • Severe pain or new neurological deficit

Differential diagnosis

  • See differentials section per chief complaint

Recommended investigations

  • CBC, basic metabolic panel as indicated
  • Targeted disease-specific tests

Diagnosis

  • Clinical diagnosis supported by targeted investigations

Initial treatment / management

  • Wash wound 15 min with soap + water + virucidal
  • Category III: PEP vaccine + RIG infiltrated into wound
  • Category II: PEP vaccine

Drug therapy

  • Cell-culture vaccine 1ml IM days 0, 3, 7, 14 (28 if immunocompromised) or intradermal regimens
  • Tetanus, antibiotics as needed

Follow-up advice

  • Review in 2–4 weeks or earlier if worsening
  • Monitor response to therapy and adverse effects

Patient counselling

  • Explain diagnosis and natural course in lay terms
  • Red-flag symptoms warranting urgent return
  • Adherence to medications and follow-up

Referral criteria

  • Refer if diagnostic uncertainty, complications, or failure of first-line therapy

Clinical pearls

  • Once symptomatic, rabies is virtually 100% fatal — never delay PEP
