I now have comprehensive information from multiple authoritative textbooks. Here is the full answer:

Mongoose Bite Management

A mongoose is a small carnivorous mammal classified as a wild mammal. Its bite is managed under the same framework as any wild or domestic mammal bite, with two core concerns: wound infection and rabies post-exposure prophylaxis (PEP), since mongooses are documented rabies reservoir/vector species in several parts of the world (Caribbean islands, South Africa, parts of Asia).

Step 1 - Immediate First Aid (Local Wound Treatment)

This is the single most important step - local wound care can reduce rabies transmission risk by up to 80%.

Step	Action
Washing	Flush and wash wound(s) immediately with soap and water under running tap for at least 15 minutes
Irrigation	Irrigate open/puncture wounds under moderate pressure with sterile saline or water; use a catheter for puncture wounds
Chemical treatment	Apply a virucidal agent - 40-70% alcohol, povidone-iodine solution, or 0.01% aqueous iodine to the wound surface and surrounding skin
Do NOT suture immediately	Bite wounds should not be sutured right away, as this can drive virus deeper into tissues
Delayed suturing	If closure is needed, delay 24-48 hours, apply minimum stitches, and infiltrate rabies immunoglobulin locally first

Park's Textbook of Preventive and Social Medicine, p. 324

Step 2 - Full Clinical Assessment

Obtain history covering three areas (Rosen's Emergency Medicine):

Circumstances of the bite: timing (bites >6 hours old have higher infection risk), provoked vs. unprovoked attack
The animal: type (wild mongoose = high rabies risk), location (captured/escaped/unknown), vaccination status
The patient: medical history, immunosuppression (diabetes, liver disease, splenectomy, prior mastectomy), tetanus status, current medications

Physical exam: Examine in a bloodless field; check tendon integrity, joint capsule violation, neurovascular status, and retained teeth fragments. Extend puncture wound margins if overlying a joint or tendon.

Step 3 - Rabies Post-Exposure Prophylaxis (PEP)

Mongooses are recognized rabies reservoir animals. PEP decision is based on WHO exposure category:

WHO Category	Type of Exposure	PEP
Category I	Touching/feeding, lick on intact skin	None
Category II	Nibbling of uncovered skin, minor scratches without bleeding	Immediate vaccination + local wound treatment
Category III	Transdermal bite(s) or scratches, lick on broken skin, mucous membrane contact	Immediate vaccination + rabies immunoglobulin (RIG) + local wound treatment

Most mongoose bites = Category III, requiring both RIG and vaccine.

Vaccine Schedules (Cell-Culture Vaccine - IM route)

Essen regimen (5-dose): Days 0, 3, 7, 14, 28 - 1 IM dose into deltoid (or anterolateral thigh in children <2 years)
Zagreb regimen (4-dose, 2-1-1): 2 doses on Day 0 (one in each deltoid), then 1 dose each on Days 7 and 21

Rabies Immunoglobulin (RIG) - for Category III

Infiltrate as much of the dose as possible directly into and around the wound
Give the remainder IM at a distant site from the vaccine

PEP can be discontinued if the animal is confirmed rabies-negative by lab testing, or if a domestic animal (dog/cat) remains healthy through a 10-day observation period from the date of bite. For wild mongooses, discontinuation is generally not applicable.

Park's Textbook of Preventive and Social Medicine, p. 324-325
Harrison's Principles of Internal Medicine 22E, p. 1189

Step 4 - Antibiotic Prophylaxis / Therapy

Mongoose = wild mammal bite. Likely pathogens include Pasteurella species, S. aureus, streptococci, anaerobes, Capnocytophaga species.

First-line:

Amoxicillin-clavulanate (oral: 875/125 mg PO q12h) - covers Pasteurella, S. aureus, anaerobes

Penicillin-allergic:

Clindamycin + TMP-SMX (1 DS tablet PO twice daily)
OR Clindamycin + Ciprofloxacin/Moxifloxacin
Note: Do NOT use erythromycin, clindamycin alone, or first-generation cephalosporins as monotherapy (high failure rate for Pasteurella)

IV options (hospitalized/severe wounds):

Ampicillin-sulbactam 3.0 g IV q6h
Add vancomycin empirically if MRSA risk is high

When to give prophylactic antibiotics:

Immunocompromised patient
Bite on hands or feet
Deep puncture wounds
Crush injuries or damage to deep structures
Delayed presentation (>6 hours)
Wounds that will be primarily closed

Duration: 3-5 days prophylaxis; 5-14 days for established infection

Harrison's Principles of Internal Medicine 22E, p. 1188
Red Book 2021, p. 327
Rosen's Emergency Medicine, p. 800

Step 5 - Tetanus Prophylaxis

Tetanus History	Action
Complete primary immunization, booster within 5 years	None needed
Complete primary, no booster in >5 years	Give tetanus toxoid booster
Incomplete/unknown immunization	Full primary immunization + tetanus immune globulin (TIG)

Harrison's Principles of Internal Medicine 22E, p. 1189

Step 6 - Wound Closure

Wound Type	Closure
Face/scalp, <6 hours old	Can suture after wound prep
Puncture wounds	Do not suture
Wounds >12 hours old	Do not suture
Infected wounds	Do not suture
High-risk areas (hand, foot)	Rarely/never suture; leave open
If closure needed	Consider delayed primary closure at 48-72 hours if no infection

Rosen's Emergency Medicine, p. 800

Step 7 - Disposition & Follow-up

Admit if any of:

Signs of systemic infection (fever, lymphangitis, sepsis)
Rapid progression of infection
Deep-space infection or joint/bone involvement
Unable to tolerate oral antibiotics
Immunocompromised

Outpatient: Re-evaluate in 24-48 hours.

Elevate and immobilize the injured limb, particularly if it is the hand.

Summary Quick Reference

Mongoose bite → 
1. Immediate soap + water wash ≥15 min
2. Virucidal agent (povidone-iodine/alcohol)
3. Assess: wound depth, location, tetanus, rabies risk
4. Rabies PEP (usually Category III): RIG + vaccine (Days 0-3-7-14-28)
5. Antibiotics: Amoxicillin-clavulanate 875/125 mg PO q12h x 3-5 days
6. Tetanus prophylaxis as indicated
7. No immediate suturing; delay 24-48h if closure needed
8. Re-evaluate in 24-48h

Mangoos bite managment

I already provided a detailed answer on mongoose bite management just moments ago. Here is a concise summary for quick reference:

Mongoose Bite Management - Quick Reference

1. Immediate Local Wound Care

Wash wound with soap and water for at least 15 minutes under running tap
Irrigate with sterile saline (use catheter for puncture wounds)
Apply virucidal agent: povidone-iodine or 40-70% alcohol
Do NOT suture immediately - delay 24-48 hours if closure is needed

2. Rabies PEP (Post-Exposure Prophylaxis)

Mongooses are rabies reservoir animals - treat as high-risk.

WHO Category	Exposure	Action
I	Intact skin contact	No PEP
II	Minor scratches, no bleeding	Vaccine only
III	Transdermal bite (most mongoose bites)	RIG + Vaccine

Vaccine schedule (IM, deltoid):

Essen: Days 0, 3, 7, 14, 28
Zagreb (2-1-1): Day 0 ×2 sites, then Days 7, 21

Rabies Immunoglobulin (RIG): Infiltrate maximum dose around the wound; remainder IM at a distant site.

3. Antibiotics

First-line: Amoxicillin-clavulanate 875/125 mg PO q12h
Penicillin-allergic: Clindamycin + TMP-SMX or Clindamycin + Ciprofloxacin
IV (severe/hospitalized): Ampicillin-sulbactam 3.0 g q6h
Duration: 3-5 days prophylaxis; 5-14 days for established infection

4. Tetanus Prophylaxis

Booster if last dose >5 years ago
Full immunization + TIG if never immunized

5. Wound Closure

Face, <6 hrs: May suture
Hands/feet, punctures, >12 hrs, infected: Do NOT suture
Consider delayed primary closure at 48-72 hrs

6. Follow-up

Reassess in 24-48 hours
Admit if: systemic infection, joint/bone involvement, immunocompromised, unable to take oral antibiotics
