Typhoid Fever risk in Rio de Janeiro

Typhoid Fever Prevention Guide for Rio de Janeiro Risk Score: 55/100 Typhoid fever is a bacterial infection caused by Salmonella Typhi, spread through contaminated food and water. Symptoms include prolonged high fever, headache, stomach pain, and weakness. Without treatment, it can become serious. Rio de Janeiro presents several specific risk factors. Informal settlements (favelas) often have inadequate sewage systems, increasing contamination. Street food vendors near beaches and tourist areas may lack proper hygiene controls. Water quality varies significantly between neighborhoods, and flooding during heavy rains mixes sewage with drinking water sources. Tourist-heavy areas like Copacabana and Ipanema see high volumes of food handling with inconsistent refrigeration. Take these steps to protect yourself: Get vaccinated before you travel. Two options exist: an injectable vaccine lasting two years or oral capsules lasting five years. Neither is 100% effective, so vaccination should complement other precautions. Drink only bottled or boiled water. Avoid ice in drinks unless you know the source. Even carbonated beverages can be contaminated with ice. Use bottled water for brushing teeth. Choose food carefully. Eat thoroughly cooked foods served hot. Avoid raw vegetables, unpeeled fruits, shellfish, and food from street vendors. Buffet food sitting at room temperature poses particular risk. Practice strict hand hygiene. Wash hands frequently with soap, especially before eating and after using the bathroom. Carry alcohol-based hand sanitizer for situations where soap is unavailable. Be cautious during rainy season. Flooding increases contamination risk across the city. Consider avoiding swimming in lagoons and standing water. Carry a medical card noting your vaccination status and know the location of hospitals with English-speaking staff, including Hospital Copa Dor and Copa Star. If you develop fever lasting more than three days with headache or stomach pain, seek medical care immediately and mention your travel history.
