Typhoid Fever risk in Zanzibar

Typhoid fever is a bacterial infection caused by Salmonella Typhi, spread through contaminated food and water. Symptoms include prolonged fever, headache, stomach pain, and weakness. In Zanzibar, risk scores 64/100 due to limited sanitation infrastructure, crowded living conditions, and food handling practices.

Zanzibar specific risks: street food vendors with inconsistent hygiene, shared water sources, and warm climate favoring bacterial growth in food. Ice in drinks from untreated water is a common transmission route.

Prevention steps:

1. Drink only bottled or boiled water. Avoid ice in drinks unless confirmed from treated sources. Use water purification tablets when bottled unavailable, boiling for 1 minute minimum.

2. Eat thoroughly cooked food served hot. Avoid raw vegetables, unpeeled fruits, and street food from vendors with visible hygiene issues. Choose busy stalls with high turnover.

3. Wash hands frequently with soap before eating and after using facilities. Carry hand sanitizer as backup.

4. Consider typhoid vaccination before travel. Injectable (one dose) or oral (four capsules) options available. Start at least 2 weeks before arrival.

5. Seek immediate medical care if fever persists beyond 3 days. Carry oral rehydration salts. Inform healthcare providers of travel history.
