How Typhoid Fever Spreads
Typhoid fever (enteric fever) is a systemic bacterial infection caused by Salmonella enterica serotype Typhi. It spreads through the fecal-oral route via contaminated street food, unhygienic water sources, or food prepared by asymptomatic carriers.
Classic Step-Ladder Fever & Symptoms
- Step-Ladder Fever: Body temperature rises stepwise each day, peaking in the evening (often reaching 104°F).
- Severe Gastrointestinal Distress: Abdominal pain, "pea soup" diarrhea in children or constipation in adults.
- Rose Spots: Faint salmon-pink spots on the trunk and abdomen that blanch upon pressure.
- Hepatosplenomegaly: Enlarged liver and spleen detected upon clinical abdominal palpation.
Why You Should Rely on Blood Culture, Not Just the Widal Test
The traditional Widal test measures agglutinating antibodies against Salmonella O and H antigens. However, the Widal test has high false-positive rates in India due to previous infections, baseline endemic antibody levels, and cross-reactions with malaria or dengue.
The Gold Standard: An automated Blood Culture test done within the first week of fever before starting antibiotics is the definitive diagnostic method that identifies the exact drug sensitivity profile.

Crucial Treatment Warning: Always complete the full prescribed 7 to 14-day course of antibiotics (such as Cefixime, Azithromycin, or Ceftriaxone) even if fever resolves on Day 4, to prevent relapse and antibiotic resistance.
