Typhoid fever is a bacterial infection that is still very much a daily reality in Indian cities, particularly during and after the monsoon season. According to the World Health Organization, typhoid affects an estimated 11 to 20 million people globally each year, with India among the highest-burden countries. In Whitefield and broader Bengaluru, the combination of monsoon-related water contamination and the large population of people eating from shared canteens and food stalls keeps typhoid a relevant clinical concern every year.

The good news: typhoid is treatable with antibiotics when caught early. The risk: it is easily confused with a regular viral fever in the first week, which delays diagnosis and allows the illness to progress to its more dangerous stages.

What Is Typhoid and What Causes It?

Typhoid fever is caused by Salmonella typhi, a gram-negative rod-shaped bacterium that infects the gastrointestinal system and spreads systemically through the bloodstream. It is transmitted through the fecal-oral route: when a person eats food or drinks water contaminated with the faeces of an infected individual.

Common routes of transmission in urban India include contaminated drinking water (particularly during monsoon when water infrastructure is stressed), food handled by asymptomatic typhoid carriers, street food and raw vegetables washed in contaminated water, and ice made from unpurified water.

Typhoid is not spread by coughing, sneezing, or casual contact with an infected person. You cannot catch it by being near someone who has it.

What Are the First Signs of Typhoid?

The incubation period for typhoid is 6 to 30 days after exposure, typically 10 to 14 days. The first signs appear gradually and are often mistaken for a common viral fever, which is the central diagnostic challenge.

Early symptoms of typhoid include:

• A fever that rises in a stepladder pattern, increasing by half to one degree each day over several days
• Headache, often persistent and dull
• Fatigue and weakness out of proportion to the degree of fever
• Loss of appetite
• Dry cough (present in about 30 percent of cases)
• Abdominal discomfort, either constipation (more common in adults) or loose stools (more common in children)
• Muscle aches

The stepladder fever pattern is the most clinically distinctive feature. Unlike dengue, which often produces a sudden spike to 40 degrees Celsius, typhoid fever builds gradually over days. By the end of the first week, fever typically reaches 39 to 40 degrees Celsius.

How Do You Get Typhoid Fever?

Typhoid is preventable through safe water practices, food hygiene, and vaccination. The typhoid conjugate vaccine (Typbar-TCV) is now included in India's Universal Immunisation Programme and is also available at Stepcare as part of their childhood vaccination packages.

Key Symptoms of Typhoid Fever by Week

 

How Long Does Typhoid Last?

Without treatment, typhoid lasts 3 to 4 weeks and progresses through all four stages. With appropriate antibiotic treatment started in the first or second week, fever typically resolves within 3 to 7 days of beginning antibiotics and the illness rarely progresses to its dangerous third-week complications.

This is why early diagnosis matters enormously. A blood culture confirming Salmonella typhi is the gold standard for diagnosis, though it takes 48 to 72 hours. The Widal test is widely used in India but has notable limitations in areas where typhoid is endemic, as background antibody levels can produce false positives. The NS1 typhoid antigen detection test and newer PCR-based tests offer faster, more specific results and are available at diagnostic centres in Whitefield.

Typhoid Fever Treatment

First-line antibiotic treatment in India depends on local resistance patterns. Current IAP and WHO recommendations:

Antibiotic resistance is a growing concern in Indian typhoid strains. Extensively drug-resistant (XDR) Salmonella Typhi, resistant to multiple antibiotic classes, is an emerging issue. This is another reason to get a confirmed blood culture and sensitivity report rather than self-treating.

Supportive care is equally important: adequate oral hydration, a soft, easily digestible diet, paracetamol for fever (not ibuprofen or aspirin, which can irritate an already inflamed gut), and rest. Bed rest is particularly important during the third week when intestinal perforation risk is highest.

Prevention: Typhoid Vaccine, Safe Water, and Food Hygiene

The Typbar-TCV typhoid conjugate vaccine provides protection for up to 5 years from a single dose and is recommended for children from 6 months of age onwards. Adults travelling to endemic areas or living in high-risk settings also benefit from vaccination. At Stepcare, typhoid vaccination is available as part of both individual and childhood vaccination packages.

Beyond vaccination: boil or filter drinking water, avoid raw vegetables and street food during the monsoon season, wash hands thoroughly before meals and after using the toilet, and avoid ice in drinks from unverified sources.
