Typhoid Fever risk in Kolkata

Typhoid fever is a serious bacterial infection caused by Salmonella Typhi, spread through contaminated food and water. In Kolkata, risk factors include monsoon flooding that mixes sewage with drinking water, street food prepared with unsafe water, inadequate hand hygiene in crowded areas, and poor sanitation in certain neighborhoods. The city's dense population and aging water infrastructure create ideal conditions for transmission. Here are practical steps to protect yourself. First, drink only safe water. Boil water for at least one minute before drinking, or use bottled water from sealed bottles. Avoid ice in drinks from street vendors as it may come from untreated water. Second, eat carefully. Choose freshly cooked, hot food. Avoid raw vegetables and fruits you cannot peel yourself. Be especially cautious with street vendors who may wash utensms in contaminated water. Stick to popular stalls with high turnover where food is freshly prepared. Third, wash hands thoroughly with soap and clean water before eating and after using the toilet. This single habit prevents transmission significantly. Fourth, consider vaccination. The injectable Vi polysaccharide vaccine provides protection for about two years. Oral Ty21a vaccine is also available. Consult your doctor before traveling or during outbreak seasons, typically June through October when flooding peaks. Fifth, report suspected cases early. If you develop sustained high fever, headache, stomach pain, or weakness lasting several days, seek medical care immediately. Early antibiotic treatment reduces complications and prevents spread to family members. Kolkata's risk score of 69 reflects these ongoing challenges. Stay vigilant during monsoon season. Keep oral rehydration salts at home. Educate household members about safe food handling. Small consistent habits protect your family effectively.
