It is for your protection to carry a first aid kit with necessary prescription drugs, plus aspirin, anti-inflammatory tablets, anti-diarrhea pills, and antibiotics.
It is best to avoid drinking tap water. Just stick to drinking bottled water to be safe.
Cholera is a risk in the country and precautions are advised.

Philippine visitors and tourists are advised to carry a comprehensive medical insurance.
