When travelling to any foreign country it is a very good idea to carry traveller’s medical insurance. If you do happen to become ill or injured while on vacation without insurance the bills can become very expensive very quickly.
Laos can be an especially expensive place to become ill in light of the fact that sometimes patients will need to be air lifted to Thailand in order to receive the best care. Such airlifts can cost upwards of $25,000.00 so it is very important that you have the proper insurance before travelling to Laos.
If there is such an emergency and you have no insurance the company responsible for medical transportation will not help you whatsoever. Make sure to receive physical evidence (a signed document) attesting to your coverage prior to leaving for Laos.
