I now have comprehensive data from Park's, Tintinalli's, and Rosen's textbooks. Let me compile the complete, detailed answer.

Dog Bite: Classification of Exposure, Post-Exposure Prophylaxis, and Wound Management

WHO Classification of Exposure (Categories I, II, III)

The WHO has established a three-category system to guide decision-making after potential rabies exposure. This system is universally used in clinical practice:
CategoryType of Contact with Suspect Rabid AnimalPEP Measures
Category ITouching or feeding animals; licks on intact skinNone required
Category IINibbling of uncovered skin; minor scratches or abrasions without bleedingImmediate vaccination + local wound treatment
Category IIISingle or multiple transdermal bites or scratches; licks on broken skin; contamination of mucous membrane with saliva from licks; contact with batsImmediate vaccination + rabies immunoglobulin (RIG) + local wound treatment
All Category II and III exposures must be assessed as carrying a risk of developing rabies and require PEP. - Park's Textbook of Preventive and Social Medicine; Tintinalli's Emergency Medicine

Factors that increase the risk in Category II and III exposures:

  • The biting mammal is a known rabies reservoir or vector species
  • The animal looks sick or has abnormal behaviour
  • A wound or mucous membrane was contaminated by the animal's saliva
  • The bite was unprovoked
  • The animal has not been vaccinated
  • The biting animal cannot be traced or identified
Important note: In developing countries, the vaccination status of the suspected animal alone should not be used to decide whether to initiate prophylaxis or not. PEP may be discontinued if the animal is proved rabies-free by laboratory examination, or if a domestic dog, cat, or ferret remains healthy throughout a 10-day observation period from the date of the bite. - Park's Textbook of Preventive and Social Medicine

Wound Management (Local Treatment)

Prompt and adequate local treatment is the first and most important step in PEP. Animal experiments have shown local wound treatment can reduce the chance of developing rabies by up to 80%. It should ideally begin within minutes of exposure but should not be neglected even if several hours or days have elapsed. - Park's Textbook of Preventive and Social Medicine
Local treatment comprises four key steps:

(a) Cleansing

Immediate flushing and washing of wound(s), scratches, and adjacent areas with copious soap and water, preferably under a running tap, for at least 15 minutes. If soap is unavailable, flushing with plain water is acceptable as first-aid. For puncture wounds, catheters should be used to irrigate the deeper recesses of the wound.

(b) Chemical Treatment (Virucidal Agents)

After cleansing, residual virus in the wound should be inactivated by irrigation with virucidal agents:
  • Alcohol (400-700 ml/litre)
  • Tincture or aqueous solution of iodine (0.01%)
  • Povidone-iodine

(c) Suturing

Bite wounds should not be immediately sutured, as this can spread the virus into deeper tissues. If suturing is unavoidable, it should be deferred by 24-48 hours, using minimum possible stitches, and performed under local cover of rabies immunoglobulin infiltrated into the wound. - Park's Textbook of Preventive and Social Medicine

(d) Antibiotics and Anti-Tetanus Measures

Application of antibiotics and anti-tetanus procedures (tetanus toxoid +/- TIG) when indicated should follow the local wound treatment steps above.

Post-Exposure Prophylaxis (PEP)

The aim of PEP is to neutralize inoculated virus before it can enter the nervous system. Irrespective of the category of wound, the combined administration of a single dose of RIG (if indicated) + a full course of cell-culture vaccine + local wound treatment is the best prophylactic regimen. - Park's Textbook of Preventive and Social Medicine

1. Vaccines Used

The internationally recommended cell-culture and embryonated egg-based vaccines (CCEEVs) include:
  • Human Diploid Cell Vaccine (HDCV)
  • Purified Vero Cell Rabies Vaccine (PVRV)
  • Purified Chick Embryo Cell Vaccine (PCECV)
  • Primary Syrian Hamster Kidney Cell vaccine
  • Primary duck embryo (embryonated egg-based) vaccine
All WHO-prequalified CCEEVs must meet a potency of ≥ 2.5 IU per single intramuscular dose. They are inactivated vaccines and can be administered to immunocompromised individuals. - Park's Textbook of Preventive and Social Medicine

2. Intramuscular (IM) PEP Regimens

Vaccine is injected into the deltoid muscle (or anterolateral thigh in children < 2 years). Gluteal injection must be avoided (poor immunogenicity due to fat tissue).
a) Essen Regimen (5-dose)
  • 1 IM dose (1.0 ml or 0.5 ml) on Days 0, 3, 7, 14, and 28
b) Zagreb (Abbreviated Multisite) Regimen (2-1-1)
  • 2 doses on Day 0 (1 each in both deltoids or thighs), then 1 dose on Day 7, and 1 dose on Day 21
c) 4-Dose Simplified Schedule
  • 1 dose on Days 0, 3, 7, and 14 - recommended for healthy, fully immunocompetent individuals who receive high-quality RIG plus WHO-prequalified vaccines. This is the current US (ACIP) schedule.
  • Park's Textbook of Preventive and Social Medicine; Tintinalli's Emergency Medicine

3. Intradermal (ID) PEP Regimen

2-site intradermal regimen (2+2+2+0+2):
  • 0.1 ml injected at 2 sites (both deltoids or thighs) on Days 0, 3, 7, and 28
  • The Day 14 dose is omitted
  • Only used in countries where the intradermal route has been endorsed by national health authorities
  • Park's Textbook of Preventive and Social Medicine; Tintinalli's Emergency Medicine

4. Rabies Immunoglobulin (RIG) - Passive Immunization

RIG is indicated only for Category III exposures and is given once only, ideally at or as soon as possible after the first vaccine dose. It must not be given after Day 7 from the first vaccine dose (as active immunity has already begun).
ProductDose
Human RIG (HRIG)20 IU/kg body weight
Equine RIG (ERIG) / F(ab')2 products40 IU/kg body weight
Administration: As much RIG as anatomically feasible should be infiltrated into and around the wound site(s). Any remaining volume is injected intramuscularly at a site distant from the vaccine injection site. RIG may be diluted in saline to allow adequate infiltration of multiple wounds. RIG should never be given in the same syringe or site as the vaccine. - Park's Textbook of Preventive and Social Medicine; Rosen's Emergency Medicine

5. PEP in Previously Vaccinated Individuals

  • Wound care + 2 IM doses (Days 0 and 3), OR 4 ID doses (all on Day 0, in 4 sites)
  • RIG is NOT required in previously vaccinated persons with documented neutralizing antibody titers ≥ 0.5 IU/mL

6. PEP in Immunocompromised Individuals

  • A complete 5-dose IM CCEEV regimen is required along with wound management and local RIG infiltration
  • Rabies-virus neutralizing antibody response should be checked 2-4 weeks after vaccination to assess if a booster is needed

Note on Advantages of Intradermal Administration of Cell-Culture Vaccines

Intradermal administration of rabies CCEEVs offers several important advantages, particularly relevant to resource-limited settings:
  1. Dose economy / Cost reduction: Each ID injection uses only 0.1 ml - approximately one-fifth of the intramuscular dose (0.5 or 1.0 ml). Multiple patients can be vaccinated from a single multidose vial, dramatically reducing the per-patient cost of the complete PEP course. The WHO recommends the ID route as an alternative to IM precisely for reasons of cost and availability.
  2. Equal immunogenicity: When administered correctly by trained staff, the intradermal route is highly efficacious and induces protective neutralizing antibody titers (≥ 0.5 IU/mL) comparable to the IM route. Studies confirm 100% of healthy individuals achieve significant antibody response with WHO-approved CCEEVs. No individual with circulating neutralizing antibody levels above 0.5 IU/mL has ever contracted rabies. - Rosen's Emergency Medicine
  3. Suitability for pre-exposure prophylaxis (PrEP) programs: The lower cost makes mass or traveler PrEP programs feasible in endemic regions, where the IM regimen would be cost-prohibitive.
  4. Same vaccine, different route: The identical CCEEV vials used for IM administration can be repurposed for ID use (in countries where endorsed), without the need for a separate product, simplifying supply chains.
  5. Multiple simultaneous vaccination sites: The ID route allows simultaneous injections at multiple sites on the same day, facilitating accelerated schedules (e.g., the 2-site ID regimen on Days 0, 3, 7, 28).
Limitations to be aware of:
  • Technically more demanding - requires proper intradermal injection technique; subcutaneous deposit gives a poor immune response
  • Staff must be specifically trained
  • Chloroquine (and possibly other antimalarials) can impair immunogenicity of intradermal rabies vaccine; these patients should receive the IM route instead
  • Not licensed for ID administration in the US postexposure setting; the US CDC recommends IM only
  • Park's Textbook of Preventive and Social Medicine; Tintinalli's Emergency Medicine; Rosen's Emergency Medicine
Summary of Key Decision Points in Dog Bite Management:
Dog bite → Assess wound category (I / II / III)
        ↓
Category I → Wash + reassure; no vaccine/RIG
        ↓
Category II → Wound treatment + full CCEEV course (IM or ID)
        ↓
Category III → Wound treatment + CCEEV + RIG (infiltrate wound first)
        ↓
Previously vaccinated? → 2 IM doses (Days 0 & 3), no RIG
        ↓
Observe animal 10 days (dog/cat/ferret) → Stop PEP if animal healthy

What's inside the PDF (5 colour-coded sections):
  1. WHO Classification of Exposure - Full Category I / II / III table with contact types, examples, and PEP recommendations; risk-increasing factors; 10-day observation rule note
  2. Wound Management - Four-step local treatment protocol (cleansing, virucidal agents, suturing rules, antibiotics/anti-tetanus) in a structured table
  3. Post-Exposure Prophylaxis - CCEEV vaccine types; IM regimens (Essen 5-dose, Zagreb 2-1-1, ACIP 4-dose); ID 2-site regimen; RIG dosing table (HRIG vs ERIG); special populations (previously vaccinated, immunocompromised, antimalarial users)
  4. Advantages of Intradermal Administration - Six advantages (dose economy, equal immunogenicity, PrEP feasibility, same-vial use, multi-site scheduling, safety) plus a highlighted limitations box
  5. Quick Decision Summary - One-page reference table mapping each scenario to wound care, vaccine, and RIG requirements
