What is Typhoid Fever?
(Salmonella Typhi Infection)
Typhoid fever = systemic bacterial infection
caused by Salmonella enterica serotype Typhi. Highly contagious
via fecal-oral route. India reports 4.5 million cases
annually – leading enteric fever burden worldwide.
Transmission Chain:
Infected person → Feces (10^6 bacteria/gm) → Contaminated
water/food → Healthy person
Incubation: 7-14 days | Infectivity: Weeks (treated), Years
(carriers)
Global Context: 11-20 million cases, 128,000 deaths
yearly (WHO 2024).
Typhoid Symptoms Timeline (WHO Classification)
Week 1: Invasion Phase
Day 3-5: Gradual fever rise (103-105°F)
Day 5-7: Relative bradycardia, coated tongue
Day 7+: Headache, myalgia, constipation (adults)
Children: Diarrhea common
Week 2-3: Toxin Phase
✅ Rose spots (25% cases) –
trunk/chest
✅ Abdominal distension, "pea
soup" stools
✅ Hepatomegaly/splenomegaly (60%)
✅ Delirium ("typhoid
state")
Complications (Untreated 10-15%)
💀 Intestinal perforation
(0.8%)
💀 GI hemorrhage (2%)
💀 Encephalopathy (1%)
💀 Myocarditis (1%)
Case Fatality: 1-4% untreated → <1% treated

Typhoid Prevention: 5-Layer Defense (Public Health)
1. Water Safety
✅ Boiled 1 min/Filtered (0.2
micron)
✅ Chlorine 0.5mg/L residual
✅ Avoid ice in endemic areas
2. Food Hygiene
✅ Peel fruits yourself
✅ Cooked >65°C kills
Salmonella
✅ No street chaat/cut fruits
3. Personal Protection
✅ Handwash 20 seconds (soap)
✅ Separate utensils for cases
✅ Vaccination pre-travel
4. Carrier Management
✅ Stool -ve ×3 → discharge
✅ Gallbladder carriers:
Ciprofloxacin 4 weeks
5. Community Surveillance
✅ School absenteeism reporting
✅ Weekly fever surveys
✅ Rapid response teams

Antibiotic Resistance Crisis (AMR Threat)
India 2026 Reality:
Nalidixic acid resistant: 80%
Fluoroquinolone resistant: 60%
Cephalosporin resistant (XDR): 20%
Carbapenem resistant: 2%
WHO Strategy: TCV vaccination + Water/sanitation.
Special Populations
Pregnancy
✅ Azithromycin safe (Category B)
✅ Ceftriaxone safe
✅ Avoid fluoroquinolones
Fetal loss risk: 5-10%
Infants <2 years
✅ Ceftriaxone IV (first line)
✅ Azithromycin alternative
Mortality: 5-10% untreated
Conclusion: Typhoid 100% Preventable – Act Now
Typhoid = fecal-oral poverty disease. Clean
water + TCV vaccine + hand hygiene = elimination possible. Early
antibiotics = 99% cure rate.
2026 Action Plan:
- Typbar-TCV
vaccination (6m-15y)
- RO
water household level
- Blood
culture fever >5 days
- Azithromycin first
line therapy
