Good preparation is personal: your health, route, season and activities matter more than a generic checklist. Start early, use qualified advice and carry insurance you have actually read.
Review a current official destination page such as CDC Travelers’ Health: Cambodia and consult an appropriate travel-health professional. This page is general preparation, not medical advice.
Before departure
Health
Discuss the actual route
Tell the professional whether you will stay in cities, visit rural or forested areas, spend time around animals, swim, trek or travel for an extended period.
Medicine
Carry what you rely on
Bring regular medicine in suitable packaging with the information you may need if it is lost or questioned. Verify restrictions before travel.
Insurance
Read beyond the headline
Confirm medical treatment, evacuation, existing conditions, motorbike use, trekking, water activities and disruption according to your plans.
Everyday risk reduction
Heat and sunStart demanding outdoor visits early, drink regularly, use shade and reduce activity if you feel unwell.
Mosquito bitesUse an appropriate repellent and clothing, especially around dawn, dusk and green or rural areas.
Food and waterChoose busy, well-kept places; drink treated water and use judgement where food storage or hygiene appears poor.
Road travelUse seatbelts when provided, prefer experienced operators and do not ride a motorbike without the skill, permission and insurance required.
AnimalsDo not handle dogs, monkeys or wildlife. Seek prompt professional advice after a bite or scratch.
Water activitiesAssess weather and currents, use a life jacket on boats and follow local closures or warnings.
If you need help
Know how to contact your insurer and identify appropriate care before travelling beyond major centres. Keep your essential medical information and emergency contacts accessible. If serious symptoms occur, seek qualified care rather than relying on a travel article or social-media recommendation.
A policy name such as “comprehensive” proves little. The wording, limits, excess, exclusions and assistance process determine what help is actually available.
