Introduction
Typhoid is a bacterial infection caused by Salmonella Typhi. It usually spreads through contaminated food or water and can become serious if not treated on time. Although typhoid is preventable and treatable, it remains common in areas where clean drinking water and proper sanitation are limited.
What Is Typhoid?
Typhoid fever is an infectious disease that affects the digestive system and can spread to other parts of the body. The bacteria enter the body through contaminated food or water and multiply in the intestines before entering the bloodstream.
Symptoms of Typhoid
The symptoms usually appear 6 to 30 days after infection. Common symptoms include:
- High fever (often above 39°C or 102°F)
- Weakness and tiredness
- Headache
- Loss of appetite
- Stomach pain
- Constipation or diarrhea
- Nausea and vomiting
- Body aches
- Dry cough
- In some cases, a pink-colored rash on the chest or abdomen
- If left untreated, typhoid can lead to serious complications.
Causes of Typhoid
- Typhoid is caused by the bacterium Salmonella Typhi. It spreads through:
- Drinking contaminated water
- Eating contaminated food
- Poor hand hygiene
- Close contact with an infected person
- Food prepared by someone who is carrying the bacteria
- Who Is at Risk?
People at higher risk include:
Children and teenagers
Travelers visiting areas where typhoid is common
People with poor access to clean water
Individuals living in crowded places with poor sanitation
Diagnosis
Doctors may recommend one or more of the following tests:
Blood culture
Stool culture
Urine culture
Typhi IgM/IgG test
Widal test (used in some places but may not always be fully reliable on its own)
A healthcare professional will interpret the test results along with symptoms.
Treatment
Typhoid should always be treated under a doctor's supervision.
Treatment may include:
Antibiotics prescribed by the doctor
Plenty of fluids to prevent dehydration
Adequate rest
Nutritious and easily digestible food
Medicines to reduce fever if recommended by the doctor

Drink clean or boiled water.
Wash your hands with soap before eating and after using the toilet.
Eat freshly cooked food.
Wash fruits and vegetables properly.
Avoid food from unhygienic places.

When to See a Doctor
Seek medical attention immediately if you have:
High fever lasting more than 2–3 days
Severe stomach pain
Persistent vomiting
Confusion or extreme weakness
Blood in the stool
Signs of dehydration
Early treatment helps prevent complications and speeds recovery.
Conclusion
