Today the planet is like a giant village; you may have breakfast in Paris, dinner in Dubai and be in China the next day. But you need to be prepared. You must be aware of each country’s requirements such as appropriate vaccines and also, what you could expect hygiene-wise.
You must have medical insurance as your provincial will only cover a very small portion, if any, of the cost of medical services outside of your home province and they certainly won’t cover repatriation in case of a major situation. So do your homework, get informed and let your insurance broker help you. Ensure that you disclose all medical conditions and prescribed medication, do not try to save money by omitting certain things, you are only shooting yourself in the foot.
