A person experiencing high typhoid fever.
Typhoid is one of those illnesses that has dropped out of public attention in most developed countries but is still very much around in India. Cases run into the millions every year nationwide, spread through contaminated water and food. The good news is that the diagnosis is well understood and antibiotic treatment usually works. The challenge is that typhoid sometimes gets missed early because the symptoms can mimic ordinary viral fever.
This is a practical guide to understanding typhoid: how it spreads, how to recognise it, how it is treated, and how to avoid getting it.
Typhoid fever is caused by Salmonella typhi, a bacterium that lives in the intestines of infected people and gets passed in their stool. Other people pick it up by drinking water or eating food contaminated with traces of that stool.
This is why typhoid is more common where sanitation is poor, water supplies are unreliable, and street food handling is less controlled. NCR sees typhoid year-round, with cases rising during monsoon when water contamination is worse.
A related illness called paratyphoid is caused by Salmonella paratyphi and behaves similarly, though usually milder.
After someone swallows the bacterium, it multiplies in the gut, enters the bloodstream, and spreads through the body. The fever and other symptoms build up over several days as the infection takes hold.
Unlike viral fevers that hit quickly and resolve in days, typhoid develops gradually and can last weeks without treatment.
Fever starts low and climbs gradually each day. Headache. Tiredness. Loss of appetite. Constipation more often than diarrhoea in adults (the opposite in children). Mild abdominal discomfort. Some people develop a dry cough.
By the end of the first week, fever is often steady around 39 to 40°C, often with the pulse remaining surprisingly slow compared to how high the fever is (a classic clinical clue).
Fever continues. Severe weakness. Significant weight loss. Abdominal pain may worsen. Some patients develop small pink spots on the chest and abdomen called rose spots (uncommon now in treated cases). The liver and spleen often become enlarged.
Mental state can become dull, sometimes confused. The Greek word "typhos," meaning a smoke or stupor, gives the illness its name.
Without treatment, this is when serious complications can develop, including:
With proper antibiotic treatment, most patients improve significantly within a few days of starting the right drug, and full recovery happens over a few weeks.
Some people, even after recovering, continue to carry the bacteria in their gallbladder and shed it in their stool for months or years. They feel normal but can spread typhoid to others. This is why long-term carriers can cause outbreaks if they work as cooks or food handlers.
A few features point toward typhoid:
A doctor will consider typhoid in any fever lasting more than a few days without an obvious viral cause.
Diagnosis is based on:
Blood culture: the gold standard, especially in the first week of illness. The bacteria can be grown from a blood sample. Takes two to three days for results.
Widal test: detects antibodies in blood. Widely available but has limitations because antibody levels can be raised from past infections or vaccination, leading to false positives. Best interpreted alongside symptoms.
Typhidot or rapid tests: faster than Widal and slightly more reliable in some settings.
Stool culture: useful in some cases, especially in the carrier state.
Bone marrow culture: most sensitive but rarely needed because it requires an invasive procedure.
Complete blood count: often shows low white blood cell count, low platelets, and sometimes mild liver enzyme elevation.
A doctor often starts treatment based on clinical suspicion plus initial test results, rather than waiting for culture results.
The treatment is antibiotics, chosen based on local sensitivity patterns. Antibiotic resistance has become a problem with typhoid in India, so the choice may need adjustment.
Common options include azithromycin, ceftriaxone (injectable), cefixime, and others. The typical course is 7 to 14 days. The fever often takes three to five days to settle even after starting the right antibiotic, so do not assume the antibiotic is not working in the first few days.
Completing the full course is essential. Stopping early when fever settles can lead to relapse, complications, or contribution to antibiotic resistance.
Hospital care is needed in severe cases, for IV antibiotics, fluids, and monitoring. Complications like intestinal perforation need surgical management.
Hydration matters. Typhoid patients are often dehydrated from poor intake and high fever.
Rest for at least the full course of antibiotics, and gradually return to normal activity afterwards.
Light easy-to-digest food: rice, dal, khichdi, boiled vegetables, fruits, soup. Avoid spicy, oily, and heavy food during illness. Adequate protein for recovery.
Avoid alcohol during the illness and for some weeks afterwards.
Stool tests after recovery to check for the carrier state, especially for people who work with food.
Most patients treated early recover fully. Complications happen mostly in untreated or late-treated cases:
Early diagnosis and proper treatment prevent most complications.
Most typhoid prevention is about safe water and food, plus vaccination for higher-risk people.
Use only filtered, boiled, or RO water for drinking and brushing teeth. Avoid ice from unknown sources. Carry your own bottled water when out, especially during monsoon.
Eat freshly cooked, hot food. Avoid food that has been sitting open for hours. Be cautious with cold buffets and undercooked items. Wash fruits and vegetables in clean water. Peel fruits yourself when possible.
Street food can be high-risk, especially items that involve uncooked ingredients (like chutneys, chaats with cold ingredients) or food prepared in conditions where water quality is uncertain. The hot, freshly fried, freshly cooked items are usually safer than the cold, pre-prepared ones.
Soap and water before eating, before food preparation, and after the toilet. Hand sanitiser when soap is not available.
Injectable Vi polysaccharide vaccine: a single shot that provides protection for about three years.
Oral live vaccine (Ty21a): a series of capsules over a week, provides protection for about five years.
Conjugate vaccine: newer, longer protection, can be given to younger children.
Vaccination is recommended for:
The vaccines are not perfect (they reduce risk by 50 to 80%), but combined with safe water and food practices, they significantly cut risk.
If someone in the family has typhoid, others can become infected through contaminated food or surfaces. Hand washing, separate utensils during the active illness, and good sanitation practices reduce household spread.
"Typhoid is rare now." It still affects millions of Indians every year.
"All long fevers are typhoid." Many other causes exist. Proper diagnosis matters.
"You can stop antibiotics when the fever settles." Stopping early can cause relapse, complications, and antibiotic resistance.
"Typhoid does not come back once you have had it." It can recur if reinfection happens or if treatment was incomplete.
"You should not eat anything during typhoid." You should eat what you can. Adequate calories support recovery.
"Home remedies cure typhoid." They support comfort and recovery but cannot replace antibiotics. Typhoid without proper antibiotics has significant mortality risk.
"All typhoid tests are reliable." Widal in particular has known limitations. Blood culture is the gold standard.
"Once you recover, you cannot infect others." Some people become carriers and shed the bacteria for months or years.
The fever has lasted more than three to five days without improvement. There is significant weight loss alongside. There is severe weakness. There is persistent constipation with fever. There is abdominal pain that is worsening. There are signs of dehydration. There has been recent travel to areas with poor sanitation. Multiple family members or contacts are unwell. You have eaten food from an unhygienic source recently.
For any fever lasting more than five days, typhoid is worth ruling out.
NCR sees typhoid cases year-round with peaks during monsoon. Water supply problems, street food, and crowded conditions all contribute.
Drink only filtered, boiled, or RO water at home. Avoid ice from unknown sources outside.
Be selective about restaurant and street food, especially during monsoon. Hot freshly cooked items are safer than cold or pre-prepared items.
Wash hands often.
Get typhoid vaccination for the family, especially children. The newer conjugate vaccine provides longer protection.
For fever lasting more than three days, see a doctor early rather than waiting it out.
For families with food handlers who have had typhoid, follow up with stool tests to rule out carrier status.

Typhoid still affects many Indians every year. It usually presents as a fever that builds up over days, with weakness, weight loss, and abdominal discomfort, lasting more than a week if untreated.
Diagnosis is by blood culture and other tests. Treatment is a 7 to 14 day course of antibiotics. Most patients recover fully if treatment starts in time and is completed properly.
Prevention is mainly about safe water, safe food, hand washing, and vaccination. The typhoid vaccine, especially the conjugate vaccine, is worth considering for the family.
For any fever lasting more than three to five days, see a doctor. Typhoid is one of the things worth ruling out, alongside dengue, malaria, COVID, and other causes.
