Untreated typhoid unfolds week by week: step-ladder fever in week one, the toxic second week, complications in week three - antibiotics cut this course short, which is why early treatment matters.
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 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".

Typhoid is prevented by safe water, hygienic food, handwashing and vaccination - India's Typhar-TCV vaccine is given at 9-12 months in the national programme and protects for years.
In typhoid, eat light, soft, high-calorie food - khichdi, dal, bananas, curd-rice, soups - with constant fluids; avoid raw salads, fried food and anything washed in unsafe water.
Typhoid starts with a slowly rising step-ladder fever, headache and weakness, often with constipation rather than diarrhoea - and any prolonged fever over 3-4 days needs a blood test.
Typhoid needs the right antibiotic - usually ceftriaxone or azithromycin in resistant India - taken for the full course; paracetamol handles fever, and no Ayurvedic product replaces antibiotics.
Typhoid splits into ordinary typhoid (Salmonella Typhi), the milder paratyphoid (Paratyphi A/B), and the dangerous drug-resistant strains - the distinction guides the antibiotic choice.
No home remedy cures typhoid - antibiotics are essential. At home the real work is fluids, rest, light food and watching for danger signs like severe abdominal pain or confusion.
