Typhoid fever is a serious bacterial infection caused by Salmonella typhi. It spreads through contaminated food and water and can lead to high fever, stomach pain, and weakness if left untreated. Understanding the stages of typhoid fever can help you recognise symptoms early and seek timely treatment.
What Causes Typhoid Fever?
Typhoid fever is caused by the Salmonella typhi bacteria, which spreads through:
Consuming food or water contaminated with infected faeces.
Poor sanitation and hygiene practices.
Close contact with an infected person.
The Four Stages of Typhoid Fever
Typhoid fever progresses in four stages, each lasting about a week if untreated. Recognising these stages helps in early diagnosis and treatment.
Stage 1: Early Symptoms (First Week)
In the first week, symptoms are mild and may resemble a common flu. They include:
Gradual fever (starts low and increases daily).
Headache and body aches.
Weakness and fatigue.
Mild stomach discomfort.
Poor appetite.
At this stage, many people mistake typhoid for a viral fever. If you have persistent fever with no improvement, consult a doctor.
Stage 2: Worsening Symptoms (Second Week)
By the second week, the fever worsens, and new symptoms appear:
High fever (103–104°F).
Severe stomach pain and bloating.
Diarrhoea or constipation.
Rose-colored spots on the chest or abdomen (in some cases).
Extreme fatigue and confusion.
Without treatment, the infection spreads, and complications can arise.
Stage 3: Serious Complications (Third Week)
If typhoid remains untreated, the third week brings life-threatening risks:
Intestinal bleeding or perforation (a hole in the intestines).
Severe dehydration.
Delirium or confusion ("typhoid state").
Risk of spreading infection to other organs.
Immediate medical care is crucial at this stage to prevent severe outcomes.
Stage 4: Recovery (Fourth Week and Beyond)
With proper antibiotics and care, fever and symptoms gradually improve. However:
Weakness may persist for weeks.
Some people become carriers (spreading bacteria without symptoms).
Follow-up tests ensure complete recovery.
How Is Typhoid Fever Diagnosed?
Doctors use the following tests to confirm typhoid:
Blood, stool, or urine tests: Detect Salmonella typhi.
Widal test: Checks for antibodies (though not always reliable).
Bone marrow test: Rarely needed for severe cases.
Early diagnosis helps in faster recovery.

Treatment Options
Typhoid is treatable with:
Antibiotics (prescribed by a doctor).
Hydration (oral rehydration or IV fluids if needed).
Rest and a nutritious diet (soft, easy-to-digest foods).
Never self-medicate—wrong antibiotics can worsen resistance.
Preventing Typhoid Fever
Prevention is better than cure. Follow these steps:
1. Get vaccinated: Two types of typhoid vaccines are available (oral and injectable).
2. Drink safe water: Boil or filter water before drinking.
3. Eat hygienic food: Avoid raw or street food; eat freshly cooked meals.
4. Wash hands frequently: Especially before eating and after using the toilet.
5. Maintain cleanliness: Ensure proper sanitation at home.
When to See a Doctor?
Consult a doctor if you have:
Persistent high fever (more than 3 days).
Severe stomach pain or diarrhoea.
Weakness and confusion.
Typhoid can be dangerous if ignored, so early treatment is key.
