Avoid raw seafood or undercooked meat unless you're at a reputable place
Use mosquito protection — dengue fever is present in urban and rural areas
Wear helmets on scooters and avoid overcrowded transport
Use hand sanitiser regularly, especially before meals
Stay hydrated and avoid heat exhaustion — Thailand can get very hot
