No matter where you are going, don't forget to take your basic health kit with you. If you get any sudden illness, Vietnam has many pharmacies, hospitals, and channelling centres to help you out, but come prepared for things you can anticipate. If you know you are allergic to a specific type of food, you may take your prescriptions and given medicine when you are travelling. Also, if you are going to explore natural attractions such as wildlife sanctuaries, forests, and nature reserves listed on sites such as Well Known Places, take a bug spray with you or any other insect repellant. Include few bandages, an antibiotic ointment, and a hand sanitiser in your first-aid kit for sure.
