Typhoid: Causes, Symptoms, Treatment & Prevention in India

19 February, 2025

Introduction – What Is Typhoid?

Typhoid fever is a serious bacterial infection caused by Salmonella typhi. It spreads through contaminated food and water and is a major health concern in many parts of India, especially during the monsoon season and in areas with poor sanitation.

According to the World Health Organization (WHO), typhoid affects an estimated 11–20 million people globally each year, with around 1.2 million deaths. India remains one of the top endemic countries, with thousands of reported cases annually.

While typhoid is treatable and preventable, if left untreated, it can lead to life-threatening complications. The key to avoiding severe outcomes is early detection, correct treatment, and proper hygiene.

Causes and How Typhoid Spreads

Typhoid spreads primarily through the fecal-oral route—meaning when people consume food or water contaminated with the feces of an infected person. This typically happens due to:

  • Drinking unsafe water
     
  • Eating unwashed fruits or vegetables
     
  • Consuming food from unhygienic street vendors
     
  • Poor personal hygiene
     
  • Lack of access to clean toilets

In India, typhoid is more common in:

  • Crowded urban areas
     
  • Places with poor waste disposal
     
  • Areas with untreated or contaminated drinking water

Once ingested, Salmonella typhi enters the intestines, multiplies, and spreads to the bloodstream, causing systemic symptoms.

Common Signs and Symptoms of Typhoid

Typhoid symptoms usually appear 6–30 days after exposure and may resemble other common fevers, which makes early diagnosis tricky. The illness tends to progress in stages.

Common symptoms include:

  • High, prolonged fever (often 102–104°F or 38.9–40°C)
     
  • Headache
     
  • Weakness or fatigue
     
  • Loss of appetite
     
  • Stomach pain
     
  • Diarrhea or constipation
     
  • Dry cough
     
  • Body aches
     
  • Skin rashes or rose-colored spots (in some cases)
     
  • Enlarged liver or spleen (detected on physical exam)

Special notes:

  • In children: Vomiting, diarrhea, and abdominal pain may be more pronounced.
     
  • In older adults: Symptoms may be mild or atypical, such as confusion or drowsiness.
     

If left untreated, the fever can last 3–4 weeks and lead to dangerous complications such as intestinal bleeding or perforation.

Stages of Typhoid Fever

If typhoid is not treated in time, it typically progresses through four stages over a span of 3–4 weeks:

Week 1 – Early Stage:

  • Gradual onset of fever (rising daily)
     
  • Headache, body ache
     
  • Loss of appetite, fatigue
     
  • Mild cough or sore throat

Week 2 – Peak Illness:

  • High-grade fever (102–104°F)
     
  • Abdominal pain, bloating
     
  • Rose spots (small, pink rashes on chest and abdomen)
     
  • Diarrhea or constipation
     
  • Mental dullness, slow heart rate (relative bradycardia)

Week 3 – Complication Stage (if untreated):

  • Intestinal bleeding or perforation (life-threatening emergency)
     
  • Low blood pressure
     
  • Severe dehydration
     
  • Delirium or confusion

Week 4 – Recovery Stage:

  • Gradual drop in fever
     
  • Return of appetite
     
  • Weakness may persist for a few weeks

Note: With early antibiotic treatment, many patients never go beyond Week 1 or 2.

Diagnosis of Typhoid

Since typhoid symptoms mimic other fevers like dengue or malaria, proper diagnosis is crucial.

Most commonly used tests in India:

  1. Widal Test – Detects antibodies to Salmonella (popular but not very accurate in early illness).
     
  2. TyphiDot Test – Quick detection of Salmonella typhi antibodies.
     
  3. Blood Culture – Gold standard test. Detects bacteria directly from blood (most reliable if done early).
     
  4. Stool or Urine Culture – Used when blood culture is not available or delayed.
     
  5. Complete Blood Count (CBC) – Often shows low WBC count and signs of infection.

Consult a physician who may recommend a combination of tests depending on the symptoms and duration of fever.

Treatment Options for Typhoid

Typhoid is treatable, especially when caught early. The primary treatment includes antibiotics to kill the bacteria and supportive care to manage symptoms.

1. Antibiotics

Your doctor may prescribe:

  • Ciprofloxacin or Ofloxacin (common for adults)
     
  • Azithromycin (increasingly used due to resistance patterns)
     
  • Cefixime or Ceftriaxone (in severe cases or resistant strains)

Do not self-medicate or stop antibiotics early — incomplete treatment can cause relapse or antibiotic resistance. 

Note: Avoid self-medication with antibiotics to prevent resistance

2. Supportive Care

  • Adequate hydration: ORS, coconut water, soups
     
  • Fever control: Paracetamol
     
  • Rest: Avoid exertion, as fatigue is common

3. Hospitalization May Be Needed If:

  • High-grade fever doesn’t subside
     
  • Patient is very weak or dehydrated
     
  • Suspected complications (bleeding, confusion, shock)
     
  • Elderly or young children affected

4. Diet Tips for Recovery

  • Light, soft, easily digestible foods (khichdi, curd rice, boiled potatoes)
     
  • High fluid intake
     
  • Avoid spicy, oily, and high-fiber foods

Potential Complications of Typhoid Fever

If typhoid is not diagnosed or treated in time, it can lead to serious and life-threatening complications, especially in children, the elderly, or immunocompromised individuals. Major complications include:

1. Intestinal Perforation or Bleeding

  • Occurs in the 3rd week of illness
     
  • Causes severe abdominal pain, bloody stools, and shock
     
  • Requires emergency surgery

2. Encephalopathy (brain involvement)

  • Confusion, drowsiness, seizures
     
  • Can lead to coma if untreated

3. Severe Dehydration and Electrolyte Imbalance

  • Due to prolonged diarrhea or vomiting
     
  • May need IV fluids

4. Pneumonia or Respiratory Complications

5. Sepsis (blood infection)

  • Bacteria enter the bloodstream, affecting multiple organs
     
  • Can be fatal without ICU care

6. Relapse

  • Fever returns days or weeks after completing antibiotics
     
  • Common if the treatment was incomplete or if the patient is a carrier

Most of these complications are preventable with early diagnosis and timely treatment.

How to Prevent Typhoid Fever

In India, where typhoid is endemic due to sanitation challenges, prevention is key. Follow these steps to reduce your risk:

1. Maintain Proper Hygiene

  • Wash your hands thoroughly with soap before eating and after using the toilet
     
  • Carry a hand sanitizer when traveling
     
  • Trim nails and avoid touching your face with unwashed hands

2. Drink Safe Water

  • Drink boiled, filtered, or packaged water
     
  • Avoid tap water, especially in unfamiliar locations
     
  • Use bottled water for brushing teeth when traveling

3. Eat Safe Food

  • Eat freshly cooked food served hot
     
  • Avoid street food, especially raw salads, chutneys, and uncovered sweets
     
  • Wash fruits and vegetables in clean water or peel them

4. Be Cautious with Children

  • Teach them hand hygiene
     
  • Avoid sending them to school with typhoid symptoms
     
  • Ensure they’re vaccinated (see next section)

When to See a Doctor?

  • If fever crosses 102°F and lasts more than 2–3 days
     
  • If accompanied by abdominal pain, diarrhea, or rashes
     
  • If you're traveling or returning from a typhoid-prone region
     
  • If a family member is diagnosed with typhoid (screen others in the household)

Typhoid Vaccination in India

Vaccination is a highly effective way to protect against typhoid fever, especially in children and people living in high-risk areas. 

1. Typhoid Conjugate Vaccine (TCV)

  • Brand names: Typbar-TCV, Zyvac-TCV
     
  • Age: Safe for children as young as 6 months
     
  • Dosing: Single shot; provides protection for up to 5 years

As part of the Universal Immunization Programme, several states have introduced the Typbar-TCV vaccine for infants.
 

2. Vi Polysaccharide Vaccine

  • For children over 2 years and adults
     
  • Requires booster every 3 years

If you live in a typhoid-prone area or plan to travel to such regions, consult your doctor about the vaccine schedule.

Who Should Get Vaccinated?

  • Children over 6 months (especially in urban areas with poor sanitation)
     
  • Food handlers
     
  • Healthcare workers
     
  • Travelers visiting high-risk areas or rural India
     
  • People with a history of typhoid or close contact with a typhoid patient

Common Myths About Typhoid — Busted

Myth

Truth

“Typhoid only happens in dirty areas.” Even clean homes can harbor typhoid if water or food is contaminated.
“It’s just a bad fever, no big deal.” Typhoid can be deadly if untreated. Intestinal perforation and sepsis are real risks.
“Once you’ve had typhoid, you’re immune for life.” Immunity is not guaranteed. Vaccination and hygiene remain essential.
“Street food that’s hot is always safe.” Not always. Even hot food can be contaminated through dirty hands or water.

‘Typhoid spreads through mosquito bites.”

It spreads through contaminated food or water, not mosquitoes.


Frequently Asked Questions (FAQs) On Typhoid

Q1: Can typhoid be spread from person to person?

A: Yes. Typhoid spreads through the fecal-oral route—when food or water contaminated with the feces of an infected person is consumed. Poor hand hygiene is a major contributor.

Q2: Can I get typhoid more than once?

A: Unfortunately, yes. Having typhoid once doesn’t give you lifelong immunity. Reinfection is possible if you’re exposed again, especially in unsanitary environments.

Q3: How long does typhoid fever last?

A: Without treatment, typhoid can last 3 to 4 weeks. With antibiotics, symptoms often improve within 3 to 5 days, but full recovery may take 2 weeks or more.

Q4: Is typhoid contagious during recovery?

A: Yes. Even after symptoms resolve, a person can shed bacteria in stool for weeks. In some cases, people become chronic carriers (e.g., “Typhoid Mary”).

Q5: Can home remedies cure typhoid?

A: No. While fluids and rest help recovery, antibiotics are essential to eliminate the infection. Delaying medical treatment can lead to complications.

Q6: When can a typhoid patient return to school or work?

A: Only after completing antibiotics and being symptom-free for at least 48–72 hours. A doctor’s clearance is advised, especially for food handlers or caregivers.

Q7: Is typhoid only a rainy season disease?

A: It’s more common during monsoon due to contaminated water and poor sanitation, but it can occur year-round in many parts of India.

Can I eat during typhoid?

Yes, but focus on soft, digestible foods and avoid raw or oily meals

Conclusion

Typhoid may be common in India, but it doesn’t have to be dangerous. With rising awareness, improved vaccines, better hygiene, and access to antibiotics, the burden of typhoid can be reduced significantly.

Make informed choices. Whether you’re a parent, a caregiver, a school teacher, or a food vendor—typhoid prevention starts with you.

If you or a loved one experiences prolonged fever or digestive symptoms, don’t wait. Visit a healthcare provider immediately. Early diagnosis saves lives.

Important points:

  • Typhoid is preventable, treatable, and serious if ignored.

     
  • Safe water, clean food, and personal hygiene are the first line of defense.

     
  • Vaccinate your children early, especially if you live in a high-risk area.

     
  • Seek medical help early if high fever persists beyond 2 days.

     
  • Avoid raw salads and roadside beverages during monsoon.

     
  • Wash hands thoroughly—especially before eating or after using the toilet.

     
  • Ensure oral rehydration during fever to prevent dehydration.
