Typhoid Fever risk in Phnom Penh

Typhoid Fever in Phnom Penh: Prevention Guide

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 Phnom Penh, the risk score sits at 65 out of 100, meaning moderate but real exposure risk, especially around street food vendors, shared water sources, and areas with limited sanitation infrastructure.

Local risk factors in Phnom Penh include untreated tap water sold by street vendors, raw salads and unpeeled fruits from local markets, ice in drinks from unknown sources, and shared dining utensils at popular food stalls along Riverside and in Toul Kork and Boeung Keng Kang areas. During the rainy season, flooding can further contaminate water supplies.

Five actionable prevention steps:

Drink only bottled or boiled water. Avoid ice unless you are certain it is made from purified water. Carry a reusable bottle and refill at trusted sources.

Eat food that is thoroughly cooked and served hot. Skip raw vegetables and unpeeled fruits from street vendors. Stick to busy food stalls where turnover is high and food is freshly prepared.

Wash your hands frequently with soap and clean water, especially before eating. Carry hand sanitizer for when soap is not available.

Consider the typhoid vaccine before arrival. The injectable vaccine offers protection for about two years. Consult a travel clinic at least two weeks before your trip.

If you develop a high fever lasting more than three days with stomach symptoms, seek medical attention immediately. Typhoid is treatable with antibiotics, but delays can lead to serious complications.

Stay cautious but not paranoid. Most visitors manage risk well by following these basic steps.
