Stages of typhoid

Stages of typhoid

Untreated, typhoid has a recognisable week-by-week course. With proper antibiotics started early, most of this never happens - the stages below describe what the illness does when diagnosis is delayed.

Week 1 - invasion and rising fever: the bacteria multiply in the intestine, enter the bloodstream and spread. Fever climbs in a step-ladder pattern from about 99°F to 103-104°F, with headache, weakness, coated tongue and often constipation. Blood culture is most likely to be positive in this week.

Week 2 - established illness: high, continuous fever. The patient looks toxic and ill: profound weakness, loss of appetite, abdominal bloating and tenderness, sometimes a slow pulse relative to the fever (relative bradycardia). Rose spots may appear on the trunk. Delirium at night, the spleen enlarges. Diarrhoea ("pea-soup" stools) may replace constipation.

Week 3 - the danger zone: this is when the classic complications strike - intestinal bleeding and intestinal perforation (a hole in the bowel wall, causing sudden severe abdominal pain and a surgical emergency), along with delirium, pneumonia, or myocarditis in severe cases. Historically, this third week carried the deaths.

Week 4 - recovery or decline: in survivors without treatment, fever gradually falls and strength slowly returns over weeks. Relapse - fever returning about 1-2 weeks after apparent recovery - occurs in some patients and needs re-treatment.

How antibiotics change the picture: started early, fever typically settles in 3-7 days and the dangerous third week is largely avoided. This is why a blood test at day 3-4 of unexplained fever is worth so much.

Remember: typhoid worsens week by week if untreated, and the third week is the dangerous one. Early testing and a full antibiotic course cut this timeline off at the start.

Ayurvedic view (interpretive)

Ayurvedic Jvara descriptions map deepening fever onto progressive dosha involvement - a rough observational parallel to these stages. The practical lesson matches: act early, do not wait for a fever to "ripen".
