You should be up to date on routine vaccinations while traveling to any destination. Some vaccines may also be required for travel.
Make sure you are up-to-date on routine vaccines before every trip. These vaccines include measles-mumps-rubella (MMR) vaccine, diphtheria-tetanus-pertussis vaccine, varicella (chickenpox) vaccine, polio vaccine, and your yearly flu shot.
Get travel vaccines and medicines because there is a risk of these diseases in the country you are visiting.
CDC recommends this vaccine because you can get hepatitis A through contaminated food or water in Cambodia, regardless of where you are eating or staying.
You can get typhoid through contaminated food or water in Cambodia. CDC recommends this vaccine for most travelers, especially if you are staying with friends or relatives, visiting smaller cities or rural areas, or if you are an adventurous eater.
Ask your doctor what vaccines and medicines you need based on where you are going, how long you are staying, what you will be doing, and if you are traveling from a country other than the US.
You can get hepatitis B through sexual contact, contaminated needles, and blood products, so CDC recommends this vaccine if you might have sex with a new partner, get a tattoo or piercing, or have any medical procedures.
You may need this vaccine if your trip will last more than a month, depending on where you are going in Cambodia and what time of year you are traveling. You should also consider this vaccine if you plan to visit rural areas in Cambodia or will be spending a lot of time outdoors, even for trips shorter than a month. Your doctor can help you decide if this vaccine is right for you based on your travel plans. See more in-depth information on Japanese encephalitis in Cambodia.
When traveling in Cambodia, you should avoid mosquito bites to prevent malaria. You may need to take prescription medicine before, during, and after your trip to prevent malaria, depending on your travel plans, such as where you are going, when you are traveling, and if you are spending a lot of time outdoors or sleeping outside. Talk to your doctor about how you can prevent malaria while traveling. For more information on malaria in Cambodia, see malaria in Cambodia.
Rabies can be found in dogs, bats, and other mammals in Cambodia, so CDC recommends this vaccine for the following groups:
There is no risk of yellow fever in Cambodia. The government of Cambodia requires proof of yellow fever vaccination only if you are arriving from a country with risk of yellow fever. This does not include the US. If you are traveling from a country other than the US, check this list to see if you may be required to get the yellow fever vaccine: Countries with risk of yellow fever virus (YFV) transmission.
For more information on recommendations and requirements, see yellow fever recommendations and requirements for Cambodia. Your doctor can help you decide if this vaccine is right for you based on your travel plans.

Bugs (like mosquitoes, ticks, and fleas) can spread a number of diseases in Cambodia. Many of these diseases cannot be prevented with a vaccine or medicine. You can reduce your risk by taking steps to prevent bug bites.
What can I do to prevent bug bites?
- Cover exposed skin by wearing long-sleeved shirts, long pants, and hats.
- Use an appropriate insect repellent (see below).
- Use permethrin-treated clothing and gear (such as boots, pants, socks, and tents). Do not use permethrin directly on skin.
- Stay and sleep in air-conditioned or screened rooms.
- Use a bed net if the area where you are sleeping is exposed to the outdoors.
What type of insect repellent should I use?
- FOR PROTECTION AGAINST TICKS AND MOSQUITOES: Use a repellent that contains 20% or more DEET for protection that lasts up to several hours.
- FOR PROTECTION AGAINST MOSQUITOES ONLY: Products with one of the following active ingredients can also help prevent mosquito bites. Higher percentages of active ingredient provide longer protection.
- Picaridin (also known as KBR 3023, Bayrepel, and icaridin)
- Oil of lemon eucalyptus (OLE) or PMD
- Always use insect repellent as directed.
What should I do if I am bitten by bugs?
- Avoid scratching bug bites, and apply hydrocortisone cream or calamine lotion to reduce the itching.
- Check your entire body for ticks after outdoor activity. Be sure to remove ticks properly.

If your travel plans in Cambodia include outdoor activities, take these steps to stay safe and healthy during your trip.
- Stay alert to changing weather conditions and adjust your plans if conditions become unsafe.
- Prepare for activities by wearing the right clothes and packing protective items, such as bug spray, sunscreen, and a basic first aid kit.
- Consider learning basic first aid and CPR before travel. Bring a travel health kit with items appropriate for your activities.
- Heat-related illness, such as heat stroke, can be deadly. Eat and drink regularly, wear loose and lightweight clothing, and limit physical activity during high temperatures.
- If you are outside for many hours in heat, eat salty snacks and drink water to stay hydrated and replace salt lost through sweating.
- Protect yourself from UV radiation: use sunscreen with an SPF of at least 15, wear protective clothing, and seek shade during the hottest time of day (10 a.m.–4 p.m.).
- Be especially careful during summer months and at high elevation. Because sunlight reflects off snow, sand, and water, sun exposure may be increased during activities like skiing, swimming, and sailing.
- Very cold temperatures can be dangerous. Dress in layers and cover heads, hands, and feet properly if you are visiting a cold location.
Stay safe around water
- Swim only in designated swimming areas. Obey lifeguards and warning flags on beaches.
- Practice safe boating—follow all boating safety laws, do not drink alcohol if driving a boat, and always wear a life jacket.
- Do not dive into shallow water.
- Do not swim in freshwater in developing areas or where sanitation is poor.
- Avoid swallowing water when swimming. Untreated water can carry germs that make you sick.
- To prevent infections, wear shoes on beaches where there may be animal waste.
Schistosomiasis, a parasitic infection that can be spread in fresh water, is found in Cambodia. Avoid swimming in fresh, unchlorinated water, such as lakes, ponds, or rivers.Hide
Most animals avoid people, but they may attack if they feel threatened, are protecting their young or territory, or if they are injured or ill. Animal bites and scratches can lead to serious diseases such as rabies.
Follow these tips to protect yourself:
- Do not touch or feed any animals you do not know.
- Do not allow animals to lick open wounds, and do not get animal saliva in your eyes or mouth.
- Avoid rodents and their urine and feces.
- Traveling pets should be supervised closely and not allowed to come in contact with local animals.
- If you wake in a room with a bat, seek medical care immediately. Bat bites may be hard to see.
All animals can pose a threat, but be extra careful around dogs, bats, monkeys, sea animals such as jellyfish, and snakes. If you are bitten or scratched by an animal, immediately:
- Wash the wound with soap and clean water.
- Go to a doctor right away.
- Tell your doctor about your injury when you get back to the United States.
Consider buying medical evacuation insurance. Rabies is a deadly disease that must be treated quickly, and treatment may not be available in some countries.Hide
Follow these tips to avoid getting sick or spreading illness to others while traveling:
- Wash your hands often, especially before eating.
- If soap and water aren’t available, clean hands with hand sanitizer (containing at least 60% alcohol).
- Don’t touch your eyes, nose, or mouth. If you need to touch your face, make sure your hands are clean.
- Cover your mouth and nose with a tissue or your sleeve (not your hands) when coughing or sneezing.
- Try to avoid contact with people who are sick.
- If you are sick, stay home or in your hotel room, unless you need medical care.
Diseases such as HIV infection can be spread through body fluids, such as saliva, blood, vomit, and semen.
- Use latex condoms correctly.
- Do not inject drugs.
- Limit alcohol consumption. People take more risks when intoxicated.
- Do not share needles or any devices that can break the skin. That includes needles for tattoos, piercings, and acupuncture.
- If you receive medical or dental care, make sure the equipment is disinfected or sanitized.
Plan for how you will get health care during your trip, should the need arise:
- Carry a list of local doctors and hospitals at your destination.
- Review your health insurance plan to determine what medical services it would cover during your trip. Consider purchasing travel health and medical evacuation insurance.
- Carry a card that identifies, in the local language, your blood type, chronic conditions or serious allergies, and the generic names of any medications you take.
- Some prescription drugs may be illegal in other countries. Call Cambodia’s embassy to verify that all of your prescription(s) are legal to bring with you.
- Bring all the medicines (including over-the-counter medicines) you think you might need during your trip, including extra in case of travel delays. Ask your doctor to help you get prescriptions filled early if you need to.
Many foreign hospitals and clinics are accredited by the Joint Commission International. A list of accredited facilities is available at their website (www.jointcommissioninternational.org).
In some countries, medicine (prescription and over-the-counter) may be substandard or counterfeit. Bring the medicines you will need from the United States to avoid having to buy them at your destination.
Malaria is a risk in some parts of Cambodia. If you are going to a risk area, fill your malaria prescription before you leave, and take enough with you for the entire length of your trip. Follow your doctor’s instructions for taking the pills; some need to be started before you leave.Hide
Motor vehicle crashes are the #1 killer of healthy US citizens in foreign countries.
In many places cars, buses, large trucks, rickshaws, bikes, people on foot, and even animals share the same lanes of traffic, increasing the risk for crashes.
Be smart when you are traveling on foot.
- Use sidewalks and marked crosswalks.
- Pay attention to the traffic around you, especially in crowded areas.
- Remember, people on foot do not always have the right of way in other countries.
Choose a safe vehicle.
- Choose official taxis or public transportation, such as trains and buses.
- Ride only in cars that have seatbelts.
- Avoid overcrowded, overloaded, top-heavy buses and minivans.
- Avoid riding on motorcycles or motorbikes, especially motorbike taxis. (Many crashes are caused by inexperienced motorbike drivers.)
- Choose newer vehicles—they may have more safety features, such as airbags, and be more reliable.
- Choose larger vehicles, which may provide more protection in crashes.
Think about the driver.
- Do not drive after drinking alcohol or ride with someone who has been drinking.
- Consider hiring a licensed, trained driver familiar with the area.
- Arrange payment before departing.
Follow basic safety tips.
- Wear a seatbelt at all times.
- Sit in the back seat of cars and taxis.
- When on motorbikes or bicycles, always wear a helmet. (Bring a helmet from home, if needed.)
- Avoid driving at night; street lighting in certain parts of Cambodia may be poor.
- Do not use a cell phone or text while driving (illegal in many countries).
- Travel during daylight hours only, especially in rural areas.
- If you choose to drive a vehicle in Cambodia, learn the local traffic laws and have the proper paperwork.
- Get any driving permits and insurance you may need. Get an International Driving Permit (IDP). Carry the IDP and a US-issued driver's license at all times.
- Check with your auto insurance policy's international coverage, and get more coverage if needed. Make sure you have liability insurance.
- Avoid using local, unscheduled aircraft.
- If possible, fly on larger planes (more than 30 seats); larger airplanes are more likely to have regular safety inspections.
- Try to schedule flights during daylight hours and in good weather.
Medical Evacuation Insurance
If you are seriously injured, emergency care may not be available or may not meet US standards. Trauma care centers are uncommon outside urban areas. Having medical evacuation insurance can be helpful for these reasons.

Healthy Travel Packing List
Use the Healthy Travel Packing List for Cambodia for a list of health-related items to consider packing for your trip. Talk to your doctor about which items are most important for you.
Why does CDC recommend packing these health-related items?
It’s best to be prepared to prevent and treat common illnesses and injuries. Some supplies and medicines may be difficult to find at your destination, may have different names, or may have different ingredients than what you normally use.
After Your Trip
If you are not feeling well after your trip, you may need to see a doctor. If you need help finding a travel medicine specialist, see Find a Clinic. Be sure to tell your doctor about your travel, including where you went and what you did on your trip. Also tell your doctor if you were bitten or scratched by an animal while traveling.
If your doctor prescribed antimalarial medicine for your trip, keep taking the rest of your pills after you return home. If you stop taking your medicine too soon, you could still get sick.
Malaria is always a serious disease and may be a deadly illness. If you become ill with a fever either while traveling in a malaria-risk area or after you return home (for up to 1 year), you should seek immediate medical attention and should tell the doctor about your travel history.
