A fever that slowly climbs higher each day, with headache, tiredness and loss of appetite — in Bangladesh, many families immediately think "typhoid". Sometimes they are right. Often, it is something else, like dengue or a viral fever.
Typhoid is a serious but treatable infection. The problem is that it is both over-diagnosed (because of unreliable tests) and sometimes treated wrongly (with the wrong or incomplete antibiotics). This guide explains typhoid symptoms, testing, treatment and prevention in simple terms.
What Is Typhoid?
Typhoid fever is an infection caused by the bacterium Salmonella Typhi. A related illness, paratyphoid, is caused by Salmonella Paratyphi. Together they are called enteric fever.
The WHO notes that typhoid is common where safe water and sanitation are limited, including parts of South Asia.
How it spreads
Typhoid spreads through food or water contaminated with faeces (stool) from an infected person. Common routes include:
- Unsafe drinking water
- Street food, cut fruit, or salad washed in unsafe water
- Food prepared by someone who did not wash hands after using the toilet
- Ice made from unsafe water
Some people carry the bacteria for a long time without feeling sick and can still spread it.
Typhoid Symptoms
Symptoms usually appear 6 to 30 days after infection (WHO). They often start gradually.
Common symptoms
- Fever that rises over several days, often high and lasting
- Headache
- Tiredness and weakness
- Loss of appetite
- Stomach pain
- Constipation or diarrhoea
- Body aches
- Cough in some people
- Sometimes faint rose-coloured spots on the chest or belly
How typhoid is different from dengue
| Feature | Typhoid | Dengue |
|---|---|---|
| Fever onset | Often gradual, climbing over days | Usually sudden and high |
| Duration | Can last 1–3 weeks or more without treatment | Usually 2–7 days |
| Body/eye pain | Less prominent | Severe muscle, joint and eye pain common |
| Stomach | Pain, constipation or diarrhoea common | Nausea, vomiting; belly pain can be a warning sign |
| Treatment | Antibiotics | No antibiotics; fluids and monitoring |
These are general patterns. Only a doctor and the right tests can tell them apart.
Example
Mitu, 19, has had fever for 6 days. It started mild and is now 103°F every evening. She has a headache, stomach pain and has not passed stool for three days. She often eats fuchka near her college. Her doctor suspects enteric fever and advises a blood culture before starting treatment.
Complications: Why Typhoid Must Be Treated Properly
Without correct treatment, typhoid can become serious. The WHO and CDC list complications such as:
- Intestinal bleeding
- Intestinal perforation (a hole in the gut) — a surgical emergency
- Confusion or reduced consciousness
- Infections in other organs
Go to hospital immediately or call 999 if there is:
- Severe or sudden belly pain, especially with a hard, swollen belly
- Black or bloody stool, or vomiting blood
- Confusion, extreme drowsiness or fainting
- Persistent vomiting and unable to drink
- Difficulty breathing
Testing for Typhoid: Blood Culture vs Widal Test
Blood culture
A blood culture is the standard test for confirming typhoid. It is most useful in the first week of fever and before antibiotics are started. It can also show which antibiotics will work (sensitivity), which is very important as resistance is increasing.
The Widal test
The Widal test is widely done in Bangladesh because it is cheap and quick. But the WHO and many experts note that it has poor accuracy in areas where typhoid is common. It can be positive in people who had typhoid or vaccination in the past, or other infections, and negative early in real typhoid.
This means a positive Widal alone is not enough to diagnose typhoid. Many people take antibiotics they do not need because of a Widal result.
Other tests
Your doctor may also order a CBC (how platelets behave in dengue is explained in dengue platelet count explained), liver function tests, or tests for dengue and malaria to rule out other causes.
Typhoid Treatment
Antibiotics — only as prescribed
Typhoid is treated with antibiotics prescribed by a doctor. The choice depends on local resistance patterns, the culture result, and how sick the patient is. Some patients need hospital admission for injections.
Important points:
- Finish the full course, even when you feel better
- Do not stop early or skip doses — this can lead to relapse and resistance
- Do not use leftover antibiotics or buy them from a pharmacy without a prescription
- If fever is not improving after a few days of treatment, tell your doctor (see also fever in adults: when to see a doctor)
The WHO has warned about drug-resistant typhoid in South Asia, including extensively drug-resistant (XDR) strains reported in Pakistan. This is why careful antibiotic use is so important.
Supportive care at home
- Drink plenty of fluids — water, ORS, soup
- Eat soft, easy-to-digest food in small portions: rice, khichuri, soup, banana, eggs
- Rest
- Paracetamol for fever, as advised
- Wash hands well, especially after the toilet, to avoid spreading it to family members
- The patient should not prepare food for others until the doctor says it is safe
Preventing Typhoid
Safe food and water
- Drink boiled, filtered or safely treated water
- Avoid ice unless you know it was made from safe water
- Eat food that is freshly cooked and served hot
- Be careful with street food, raw salads and cut fruit
- Peel fruit yourself after washing hands
Hand hygiene
- Wash hands with soap after using the toilet and before cooking or eating
- Teach children to do the same
Typhoid vaccine
The WHO recommends typhoid conjugate vaccine (TCV) for use in countries where typhoid is common. Ask your doctor or local EPI centre about current eligibility and availability for your family. Vaccines lower risk, but do not replace safe water and hygiene.
Frequently Asked Questions
What are the first signs of typhoid?
Usually a fever that rises gradually over several days, with headache, weakness, loss of appetite and stomach discomfort.
Is Widal test reliable for typhoid?
Not on its own. It can give false positive and false negative results. A blood culture is more reliable, especially in the first week.
How long does typhoid take to cure?
With the right antibiotic, many people start feeling better within a few days, but you must finish the full course. Recovery of strength can take longer.
Can typhoid come back?
Yes, relapse can happen, especially if treatment was incomplete. Contact your doctor if fever returns.
What should I eat during typhoid?
Soft, light food and plenty of fluids. There is no need to stop eating; small frequent meals help.
Is typhoid contagious?
It spreads through contaminated food and water, not by casual contact. Good handwashing protects family members.
Talk to a Doctor About a Persistent Fever on ShifaMate
If you have had fever for several days without danger signs, you can consult a verified doctor through ShifaMate. Share your fever record, symptoms and any test reports (CBC, blood culture, Widal) as photos. The doctor can advise which tests make sense and whether you need in-person care. A digital prescription may be issued when clinically appropriate. You can also browse ShifaMate doctors.
Severe belly pain, bloody stool or confusion means go to hospital now.
