Rat Bite Fever (RBF / चूहे के काटने की बुखार) एक दुर्लभ लेकिन गंभीर bacterial infection है, जो Rat (चूहा) या अन्य rodents के काटने या उनके संपर्क से फैलती है।
यह मुख्य रूप से Streptobacillus moniliformis या Spirillum minus bacteria के कारण होती है।
RBF अक्सर developing countries और rodent-infested areas में पाई जाती है और untreated cases में severe complications जैसे endocarditis, septic arthritis और multi-organ failure हो सकते हैं।
Rat Bite Fever क्या है? (What is Rat Bite Fever)
- Zoonotic bacterial infection transmitted from rats or rodents
- Two types:
- Streptobacillary Rat Bite Fever – caused by Streptobacillus moniliformis (common in USA, Europe)
- Spirillary Rat Bite Fever (Sodoku) – caused by Spirillum minus (common in Asia)
- Can occur via bite, scratch, or ingestion of contaminated food/water
Rat Bite Fever के कारण (Causes of Rat Bite Fever)
- Direct rat bite or scratch
- Contact with urine, feces, or saliva of infected rodents
- Contaminated food or water (especially milk or unpasteurized products)
- Immunocompromised individuals at higher risk

Incubation Period
- Streptobacillary: 3–10 days after exposure
- Spirillary: 1–3 weeks
Primary Symptoms
- Fever (उच्च बुखार)
- Chills (सर्दी लगना)
- Headache (सिरदर्द)
- Vomiting and nausea (उल्टी और मिचली)
Secondary Symptoms
- Rash (spots, usually on hands and feet)

- Rare: endocarditis, meningitis, septic arthritis
Rat Bite Fever कैसे पहचानें? (Diagnosis / How to Identify Rat Bite Fever)
1. Clinical History
- Recent rat bite, scratch, or rodent exposure
- Symptom pattern: fever, rash, joint pain
2. Laboratory Tests
- Blood culture for Streptobacillus moniliformis
- PCR testing (if available)
- CBC, liver and kidney function tests for complications
3. Differential Diagnosis
- Typhoid fever
- Leptospirosis
- Meningococcemia
- Viral exanthems
Rat Bite Fever का इलाज (Treatment of Rat Bite Fever)
1. Antibiotic Therapy (Primary Treatment)
- Penicillin G: drug of choice (IV for severe cases)
- Doxycycline or Tetracycline: for penicillin-allergic patients
- Cephalosporins: alternative therapy
2. Symptomatic Treatment
- Antipyretics for fever (Paracetamol)
- Analgesics for joint and muscle pain
- Hydration and nutritional support
3. Management of Complications
- Endocarditis: prolonged IV antibiotics
- Septic arthritis: joint drainage and antibiotics
- Multi-organ involvement: supportive care in hospital
Rat Bite Fever कैसे रोके? (Prevention)
- Avoid contact with rats and rodents
- Proper sanitation and rodent control at home and workplace
- Wash hands after handling animals or contaminated surfaces
- Cover food and water to prevent contamination
- Prompt wound care after rat bites (cleaning and antiseptic application)
घरेलू उपाय (Home Care / Supportive Measures)
- Immediate washing of bite or scratch site with soap and water
- Apply antiseptic to prevent secondary infection
- Rest and maintain hydration
- Monitor for early signs of fever, rash, or joint pain
- Seek prompt medical attention if symptoms develop
सावधानियाँ (Precautions)
- Do not ignore rat bites or scratches
- Seek immediate medical care if fever develops after rodent exposure
- Avoid self-medication with incomplete antibiotic courses
- Monitor children and immunocompromised individuals closely
- Maintain good hygiene and rodent-free environment
