Typhoid is still very common in India. Here is how to recognise it in children, why long-lasting fevers need investigation, and how vaccination helps.
Key Points
- Typhoid presents with prolonged fever (1–3 weeks), headache, abdominal pain, and constipation or diarrhoea.
- India accounts for 25% of global typhoid burden — contaminated water and food are the primary routes.
- Blood culture is the gold standard diagnosis — the Widal test is unreliable and often misinterpreted.
- Antibiotic resistance is rising — fluoroquinolone-resistant typhoid requires cephalosporins or azithromycin.
- Typhoid conjugate vaccine (TCV) is now recommended by IAP from age 6 months.

"I treat typhoid every week in Hyderabad. The Widal test — which most labs still use — gives false positives constantly. Blood culture is how you actually diagnose typhoid. Treating on a Widal result alone is not good medicine."
Typhoid fever — caused by Salmonella typhi — remains one of the most common bacterial infections in Indian children. Despite being preventable by vaccine and treatable with antibiotics, it continues to cause significant illness, largely because of contaminated water and food.
How Does Typhoid Spread?
Typhoid is spread through contaminated food and water — the faecal-oral route. Infected stool contaminating drinking water or food preparation is the main mechanism. Street food, unfiltered water, raw vegetables washed with tap water, and contaminated ice are common sources.
Symptoms in Children
Typhoid in children often presents differently from the "classic" adult presentation:
- Persistent fever for more than 5 days — often rising gradually over days
- The fever is characteristically "step-ladder" (rises each day)
- Headache, malaise, and general aches
- Abdominal pain (typically around the navel)
- Either constipation OR diarrhoea — either can occur
- Reduced appetite
- Mild liver enlargement
- In younger children, presentation may be more non-specific — just high fever and poor feeding
Diagnosis
- Blood culture: The gold standard — most accurate in the first week of illness
- Widal test: Widely used in India but has significant limitations — many false positives and false negatives; should not be used alone for diagnosis
- Typhidot test and ELISA: More specific antibody tests
Treatment
Typhoid is treated with appropriate antibiotics — usually for 14 days. Antibiotic choice depends on local sensitivity patterns, as drug-resistant typhoid (ESBL-producing Salmonella) is increasingly common. Ceftriaxone (IV) for hospitalised children, or azithromycin/cefixime for outpatient management in mild cases. Always complete the full course.
Complications (intestinal perforation, haemorrhage) are serious but uncommon with early treatment.
Prevention: Vaccine Available
Typhoid vaccines are available and recommended by IAP:
- Typhoid Conjugate Vaccine (TCV) — Typbar TCV: Recommended from 9 months of age. Single dose, licensed for children from 9 months. Preferred vaccine due to long-lasting immunity.
- Polysaccharide vaccine (Typherix/Typhim Vi): From 2 years, requires repeat every 3 years
"Safe drinking water and good hand hygiene are the most powerful tools against typhoid. Until infrastructure guarantees this for everyone, vaccination provides crucial individual protection."
