Cambodia
Risk:
Moderate-High
Health Overview
Cambodia's biggest health planning factor is the limited quality of in-country healthcare — even Phnom Penh's best hospitals are below regional standards, and serious illness or injury requires evacuation to Bangkok. Malaria remains a genuine risk in rural and forested areas with drug-resistant strains. Dengue is endemic nationwide. Traveler's diarrhea rates are very high. The prepared traveler has Bangkok evacuation coverage confirmed, carries a comprehensive kit, and understands that medical self-reliance is essential outside Phnom Penh and Siem Reap. Be sure to consult your Dr. prior to travel to discuss
Key Health Risks
Moderate-High
Malaria
Drug-resistant P. falciparum in forested areas. Cambodia is the epicenter of artemisinin resistance. Atovaquone-proguanil or doxycycline only. Prophylaxis essential for any rural/forest travel.
High
Dengue Fever
Endemic nationwide including Phnom Penh and Siem Reap. Peak during rainy season May-Nov. DEET and permethrin essential.
Very High
Traveler's Diarrhea
Extremely common. Carry azithromycin for self-treatment. Avoid all tap water, ice from unknown sources, and raw foods.
Health Risk Callout
Cambodia has the world's highest concentration of artemisinin-resistant malaria. Drug choice for prophylaxis matters critically here.
Other Health Risks
Rabies (stray dogs very common), tuberculosis exposure, soil-transmitted helminths, avian influenza (poultry contact), landmine injuries in rural areas (stay on marked paths)
Regional Information
Regional Risk Callout
Phnom Penh and Siem Reap (Angkor Wat) have the best available medical facilities but these remain limited. Rural provinces and forested areas carry malaria risk with multi-drug-resistant P. falciparum. Thai-Cambodia border area has active military conflict — do not travel within 50km of the border. Sihanoukville has deteriorating security conditions.
Regional Healthcare Callout
Siem Reap has basic private clinics. Rural Cambodia has essentially no reliable healthcare — mission workers must be medically self-sufficient. Bangkok is the evacuation destination for anything serious.
Vaccine and Malaria Prevention
💉 Entry Vaccine Required
Yellow Fever vaccination required if arriving from a country with YF risk.
🛡️ Recommended Vaccines
CDC recommends Hepatitis A, Typhoid, Hepatitis B, Japanese Encephalitis, Rabies, Malaria prophylaxis, Routine (Tdap, MMR, Flu, COVID-19)
🦟 Malaria Information
- Risk Level: Moderate-High
- Areas: Forested areas throughout the country, especially western provinces (Pailin, Battambang) and northeastern provinces. Minimal risk in Phnom Penh and Siem Reap/Angkor Wat.
- Recommended Drug: Atovaquone-proguanil (Malarone) or Doxycycline
- Drug Resistance: Yes
Cambodia is the global epicenter of artemisinin-resistant P. falciparum. Mefloquine resistance is also present. Only atovaquone-proguanil or doxycycline should be used for prophylaxis. This is not a country where you can skip malaria prophylaxis for rural travel.
Moderate-High
Physician Note

Emergency Medicine · 25+ Years · 40+ Countries
I've volunteered in rural Cambodia and it was one of the most impactful and most challenging experiences of my career. The healthcare infrastructure outside Phnom Penh is genuinely minimal. For travelers: the malaria situation in Cambodia is uniquely important.
This is where artemisinin resistance was first identified. Dengue is everywhere, including the tourist circuits around Angkor. Rabies from stray dogs is a real and underappreciated risk.
Your evacuation plan to Bangkok is your safety net. Make sure it's real. Amazing country, fantastic people, but Global Rescue is an imperative
Pre-Departure Checklist
8+ Weeks
- Be sure to consult your Dr. prior to travel to discuss
- CDC recommends Complete Hep A/B, Typhoid, JE, and rabies series. Begin malaria prophylaxis planning.
2-4 Weeks
- Fill atovaquone-proguanil or doxycycline
- Purchase evacuation insurance that explicitly covers Cambodia-to-Bangkok transfer
- Assemble comprehensive medical kit
- Register with STEP
Day Of
- Pack full mosquito protection including treated bed net
- Carry prophylaxis and TD treatment
- Print Bangkok hospital contacts and evacuation plan
Trip Type Guidance
Adventure
- Angkor Wat is manageable with standard precautions
- Jungle trekking requires malaria prophylaxis and comprehensive kit.
Mission
- Rural Cambodia requires the highest level of medical self-sufficiency — bring complete clinical supplies and confirm Bangkok evacuation coverage
Notes
Special Evacuation Notes
Bangkok evacuation is standard — approximately 1 hour by air ambulance from Phnom Penh. Confirm evacuation coverage explicitly includes Cambodia-to-Bangkok transfer.
Safety Notes
Bag snatching from motos is the most common crime against tourists in Phnom Penh. Landmines remain a hazard in rural areas — never walk off marked paths. Thai-Cambodia border conflict zone — avoid within 50km. Sihanoukville has seen rising crime.
