Study Notes
Rabies
- Estimated 55,000 deaths annually worldwide, predominantly in Asia (56%) and Africa (43.6%)
- Highly fatal, with symptoms including consciousness fluctuations, spasms, and autonomic instability
- Neglected disease affecting poor and vulnerable populations
- Limited reporting of deaths, particularly in remote rural communities
- Lack of preventative measures in areas with dog-to-human transmission
- Under-reporting hinders international resource mobilization for rabies elimination
Philippines Scenario
- Rabies remains a public health problem in the Philippines
- Most acutely fatal infectious disease, causing 200-250 deaths annually
- One-third of deaths in children under 15 years
- Two-thirds of cases are males
Modes of Transmission
- Bites from infected animals, particularly dogs and cats, are the most common mode
- Exposure can also come from other domestic and wild animals, including bats
- Non-bite exposures are less common but may include scratches, open wounds, and mucous membranes licked by an infected animal
- Bites from rats, rabbits, rodents, reptiles, and birds do not pose a risk for rabies infection
Pathogens
- Incubation Period: 1-3 months, with 90-95% of cases having an incubation period of less than one year, but longer periods in 5-10% of cases
- Factors influencing incubation: amount of virus, severity, and location of exposure
- Rabies virus multiplies in muscle cells or may directly invade nerves
Diagnosis
- Often based on clinical manifestations and exposure history
- Hydrophobia and/or aerophobia pathognomonic; however, paralytic rabies may pose diagnostic challenges
- Laboratory confirmation is necessary
- Diagnosis performed on fresh tissue specimens stored at appropriate temperatures
Rabies Post-Exposure Prophylaxis
- Crucial for individuals directly exposed to suspected rabid animals
- Initiation should not be delayed, regardless of exposure-to-consultation interval
- Delay increases the risk of rabies and is associated with treatment failure
Categories of Exposure
- Category I: Feeding/touching an animal, licking of intact skin, exposure to patients with signs and symptoms of rabies, casual contact
- Category II: Nibbling of uncovered skin, minor/superficial scratches/abrasions without bleeding, including those induced to blood
- Category III: All Category II exposures on the head and neck area
Management of Exposure
- Category I: Wash exposed skin immediately with soap and water, no vaccine or Rabies Immune Globulin (RIG) needed
- Category II: Wash wound with soap and water, start vaccine immediately, complete regimen until Day 28
- Category III: Wash wound with soap and water, start vaccine and RIG immediately, complete regimen until Day 28
Special Considerations
- Pregnancy and infancy not contraindications to PEP
- Babies born to rabid mothers should receive rabies vaccination and RIG upon birth
- Exposed persons evaluated weeks or months after the bite should be managed as if the exposure occurred recently
Rabies Vaccination in the Philippines
- Vaccine-preventable disease
- Animal Bite Treatment Centers (ABTC) established for PEP
- Intradermal (ID) regimen recommended for cost-effectiveness
- WHO-approved vaccines for ID use required
