Cambodia is a favorite for temples, beaches, and food adventures. It’s also a country where typhoid fever is a real travel risk. The good news is that you can reduce that risk with the right vaccine plan and smart food and water habits.
This guide is built for travelers who want clear, supportive guidance. You’ll learn why typhoid is a concern in Cambodia, how to choose a vaccine, how to time it, and what to do if you get sick.
Is Typhoid a Risk in Cambodia?
Yes. The CDC recommends typhoid vaccination for most travelers to Cambodia, especially those staying with friends or relatives or visiting smaller cities or rural areas. CDC’s Cambodia traveler page lists typhoid as a recommended vaccine for most travelers.
The CDC’s Yellow Book also notes that typhoid and paratyphoid fever are endemic in Cambodia, and travelers are at risk, particularly during longer trips or visits to remote regions. CDC Yellow Book Cambodia guidance provides more context on food- and water-borne risks and why vaccination matters.
How Typhoid Spreads
Typhoid fever is caused by Salmonella Typhi bacteria. It spreads when people consume food or water contaminated by the bacteria, usually through fecal-oral transmission. CDC’s clinical overview explains the primary transmission route and why safe food and water practices are critical for travelers.
Vaccines help reduce risk, but they are not 100% protective. The CDC stresses that vaccinated travelers should still follow careful food and water precautions. CDC prevention guidance lays out those steps.
Cambodia Itinerary Factors That Increase Risk
Risk is higher when you move beyond major tourist centers, take long overland trips, or eat at places with inconsistent sanitation. The CDC Yellow Book highlights that food-borne infections are common in Cambodia and recommends avoiding unsafe water, ice, and food from street vendors unless it is steaming hot. Yellow Book Cambodia guidance offers detail on these risks.
Use the Cambodia destination page and Cambodia travel information to review broader health considerations for your trip.
Who Should Get the Typhoid Vaccine for Cambodia?
The CDC recommends typhoid vaccination for most travelers to Cambodia. It’s especially important for:
- People visiting friends or relatives
- Travelers spending time in smaller cities or rural areas
- Anyone who will eat outside of major hotels or resorts
- Longer trips or frequent travel to Cambodia
If you’re unsure, a travel health consultation can help you match your itinerary with the right vaccine plan. You can also review general information on the Runway Health typhoid page.
Typhoid Vaccine Options (Oral vs. Injectable)
In the U.S., there are two typhoid vaccine options for travelers:
- Injectable typhoid vaccine (shot): One dose at least 2 weeks before travel; booster every 2 years if ongoing risk.
- Oral typhoid vaccine (capsules): Four doses taken every other day; finish the series at least 2 weeks before travel; booster every 5 years if ongoing risk.
The CDC provides the timing and booster guidance for both options. CDC vaccine guidance summarizes schedules and age eligibility. For a deeper comparison, read Typhoid Vaccine: Oral vs. Injection.
Runway Health can prescribe the oral typhoid vaccine after a quick online consultation.
Planning Your Vaccine Timeline
Give your body enough time to build protection. The CDC recommends completing vaccination before departure. CDC timing guidance suggests planning at least a few weeks before travel when possible.
- Injectable shot: get it at least 2 weeks before departure.
- Oral capsules: complete the series at least 2 weeks before departure.
- Last-minute travel: consult a clinician as soon as possible to review options.
Traveling With Kids or a Group
Families should plan early, especially if younger children are traveling. The CDC notes that the injectable typhoid vaccine is approved for travelers age 2 and up, and the oral vaccine is approved for age 6 and up. CDC vaccine guidance includes the age requirements.
If you are coordinating a group trip, aim to schedule vaccines together so no one misses the timing window. Group travel also means shared meals, which can increase exposure if food and water habits slip.
Do You Need a Booster?
If you’ve been vaccinated before, check when it was given. The CDC notes that injectable boosters are recommended every 2 years for ongoing risk and oral boosters every 5 years. CDC booster guidance covers the details.
Food and Water Safety in Cambodia
Vaccination is only part of prevention. The CDC recommends safe food and water habits for all travelers. CDC prevention guidance provides the core practices:
- Drink sealed, factory-bottled water or water that has been boiled.
- Avoid ice unless you’re confident it was made with safe water.
- Eat food that is fully cooked and still hot.
- Avoid raw produce you can’t peel yourself.
- Skip street food unless it is steaming hot when served.
- Wash or sanitize your hands before eating.
Practical Tips for Markets, Street Food, and Day Trips
Cambodia’s street food and night markets are part of the experience. Choose vendors with high turnover, watch food being cooked, and avoid items that have been sitting out. If you’re taking long bus rides or day trips, pack simple snacks so you can skip questionable meals without going hungry.
Keep hand sanitizer in your day bag and use it before every meal. Small habits add up over a multi-day itinerary.
What To Pack for Typhoid Prevention
- Alcohol-based hand sanitizer for before meals
- Disinfecting wipes for phones and hands on travel days
- A reusable bottle you can fill with sealed or treated water
- Simple snacks for long transit days
These items are lightweight, but they make consistent prevention easier, especially when plans change or meals are rushed.
Create a Simple Travel Health Plan
A short plan makes it easier to stay consistent with prevention across a long trip. Before you leave, write down a few basics:
- Where you will keep hand sanitizer and wipes for quick access
- How you will handle water on long travel days
- Who to contact if you develop a high fever
- Where your vaccine documentation is stored
Small, repeatable routines matter more than perfect decisions in the moment.
Have a Plan for Medical Care
Before you depart, identify how you will access medical care if you get sick. Save emergency contact numbers, confirm your travel insurance details, and know where clinics are located in the areas you will visit. If you develop a high fever, early evaluation can make a big difference.
If your trip includes remote areas, ask your hotel or tour operator where to seek care and how to reach a clinic quickly.

Recognizing Typhoid Symptoms
Typhoid symptoms often build gradually and can include fever, headache, stomach pain, weakness, constipation or diarrhea, and sometimes a rash. The CDC’s Yellow Book outlines these symptoms and the typical course of illness. CDC Yellow Book typhoid chapter summarizes the clinical presentation.
The incubation period is often 6–30 days after exposure, which means symptoms can appear during travel or after you return home. CDC Yellow Book guidance details this timing.
What To Do If You Get Sick
Typhoid requires antibiotics, and early treatment matters. If you develop a high fever during travel, seek medical care quickly. If symptoms appear after you return home, tell your clinician about recent travel to Cambodia so typhoid is considered in the diagnosis.

- Schedule a travel health consult 3–4 weeks before departure.
- Choose the right typhoid vaccine for your timing and age.

Frequently Asked Questions
Q: Do I need the typhoid vaccine if I’m only visiting Siem Reap?
Most travelers to Cambodia are advised to get vaccinated, even for short trips, especially if they’ll eat local food or travel beyond major tourist areas. The CDC lists typhoid vaccination as recommended for most travelers to Cambodia.
Q: How far in advance should I get vaccinated?
For the injectable shot, get vaccinated at least 2 weeks before travel. For oral capsules, complete the series at least 2 weeks before travel. CDC timing guidance provides the standard recommendations.
