Typhoid Fever: Symptoms, Diagnosis, and Hospital Treatment

Typhoid fever remains one of the most common infectious diseases in India, particularly in cities like Bhopal where contaminated water and food can be a concern during monsoon and summer months. Understanding its symptoms, getting the right diagnostic tests, and receiving timely treatment can prevent serious complications.

What is Typhoid and How Does It Spread?

Typhoid fever is caused by the bacterium Salmonella typhi. It spreads through:

• Contaminated water: Drinking untreated or improperly filtered water is the most common cause in Bhopal.
• Contaminated food: Eating food prepared with unwashed hands or washed with contaminated water, especially street food and raw salads.
• Poor sanitation: The bacteria pass through the stool of an infected person and can contaminate water supplies.
• Carrier transmission: Some people carry the bacteria without symptoms and can spread it unknowingly through food handling.

Typhoid does not spread through coughing, sneezing, or casual contact.

Symptoms of Typhoid Fever

Typhoid symptoms develop gradually over 1-3 weeks after exposure:

Week 1

• Gradually rising fever that increases each day, often reaching 103-104°F by the end of the week
• Headache and body aches
• Fatigue and general weakness
• Loss of appetite
• Mild cough

Week 2

• Sustained high fever (does not fluctuate much during the day)
• Abdominal pain and bloating
• Constipation (more common in adults) or diarrhea (more common in children)
• Rose spots - small, flat, pink spots on the chest and abdomen (not always visible on darker skin)
• Enlarged liver and spleen

Week 3 (If Untreated)

• Severe complications can develop, including intestinal bleeding or perforation
• Extreme weakness and weight loss
• Delirium or confusion (this is where the name "typhoid" comes from, meaning "stupor")

How is Typhoid Diagnosed?

Several tests are used to diagnose typhoid. Understanding them helps you know what your doctor is looking for:

Widal Test

• The most commonly ordered test in India
• Detects antibodies against Salmonella typhi
• Limitations: Can give false positives in people who have had typhoid before or have been vaccinated. A single Widal test is not very reliable. Doctors look for a rising titre (increasing antibody levels) in tests done 1 week apart.
• Usually becomes positive only after 7-10 days of illness

Typhidot Test (IgM)

• More specific than the Widal test
• Detects IgM antibodies, indicating a current infection
• Can give results within a few hours
• More reliable than a single Widal test

Blood Culture

• The gold standard for typhoid diagnosis
• A sample of blood is cultured to grow the bacteria
• Most accurate in the first week of illness, before antibiotics are started
• Takes 2-3 days for results
• If positive, confirms typhoid with certainty

Other Supportive Tests

• CBC: May show low WBC count (leucopenia) and mildly elevated liver enzymes
• Stool and urine culture: Can detect the bacteria, especially useful for identifying carriers

When Does Typhoid Require Hospitalization?

Most uncomplicated typhoid can be treated at home with oral antibiotics. However, hospitalization is needed if:

• Persistent vomiting making it impossible to take oral medicines or fluids
• High fever not responding to antibiotics after 5-7 days
• Severe abdominal pain or distension (risk of intestinal perforation)
• Blood in stool (intestinal bleeding)
• Extreme weakness, confusion, or drowsiness
• Typhoid in children under 2 years or elderly patients
• Patients with other conditions like diabetes, heart disease, or weak immunity

Treatment of Typhoid Fever

Antibiotic Therapy

• Typhoid is treated with specific antibiotics prescribed by a doctor
• Do not self-medicate with leftover antibiotics. Wrong antibiotics or incomplete courses lead to drug-resistant typhoid, which is harder to treat
• The full course of antibiotics (usually 7-14 days) must be completed even if you feel better
• In drug-resistant cases, your doctor may need to change the antibiotic based on blood culture sensitivity reports

Supportive Treatment

• Adequate fluids: Water, ORS, coconut water, buttermilk, and clear soups
• Paracetamol: For fever control
• Rest: Complete bed rest until fever subsides
• Monitoring: Regular temperature checks and follow-up blood tests

Diet During Typhoid Recovery

What you eat during and after typhoid is crucial for recovery:

Foods to Eat

• Soft, easily digestible foods: Khichdi, daliya (porridge), boiled rice, moong dal
• Boiled vegetables: Lauki (bottle gourd), potato, carrots
• Fruits: Bananas, apples (without skin), papaya
• Fluids: Coconut water, ORS, buttermilk, clear soups, boiled and cooled water
• Curd/yogurt: Helps restore gut bacteria
• Boiled eggs: Good source of protein during recovery

Foods to Avoid

• Spicy, oily, and fried food: Puts strain on the weakened digestive system
• Raw vegetables and salads: Risk of reinfection
• Street food: Avoid completely until fully recovered
• High-fiber foods: Whole grains, raw fruits with skin (can irritate the intestines)
• Caffeine and carbonated drinks: Can worsen dehydration

Frequently Asked Questions

Q: How long does typhoid fever last? With proper antibiotic treatment, fever usually comes down within 3-5 days. Full recovery takes 2-4 weeks. Without treatment, typhoid can last for weeks and become life-threatening.

Q: Can typhoid come back after treatment? Yes, relapse occurs in about 5-10% of cases, usually 1-2 weeks after completing antibiotics. This is why completing the full antibiotic course and follow-up testing are important.

Q: Is the Widal test accurate? A single Widal test has limited accuracy. Doctors rely on rising titres (two tests done a week apart), or prefer the Typhidot IgM test and blood culture for more reliable results. Do not diagnose yourself based on one Widal report.

Q: Is there a vaccine for typhoid? Yes, typhoid vaccines are available and recommended for people in high-risk areas. The injectable vaccine provides protection for about 2-3 years. Talk to your doctor about vaccination.

Q: Can a typhoid carrier spread the disease without being sick? Yes, some people carry Salmonella typhi in their gallbladder for months or years without symptoms. They can spread the disease through food handling. Proper hand hygiene is essential.

Preventing Typhoid in Bhopal

• Drink only purified or boiled water: Avoid drinking tap water directly. Use RO purifiers or boil water for at least 1 minute.
• Eat freshly cooked food: Avoid food that has been sitting at room temperature for hours.
• Wash hands thoroughly: With soap before eating and after using the toilet.
• Avoid street food during monsoon: Especially raw juices, cut fruits, and salads from roadside vendors.
• Get vaccinated: Especially if you live in an area with poor water supply.
• Maintain hygiene at home: Wash fruits and vegetables with clean water before cooking.

Conclusion

Typhoid is a preventable and treatable disease, but it requires the right antibiotics, proper diagnosis, and adequate rest. Do not ignore a fever that lasts more than 3-4 days, especially if it is accompanied by abdominal pain and weakness. Early testing and treatment prevent complications like intestinal perforation, which can become a surgical emergency.
