Absolutely. International travel always involves risk. There is a possibility that a personal emergency may necessitate your early return home or you may require medical attention (hospitalization, accident or personal injury, and/or even air evacuation). That is why having appropriate health insurance for travel is imperative.
Your regular health insurance may not cover international travel but a travel health insurance will. You will need to check with your current health insurance company to make sure you have the coverage you need during the program’s duration in-land as well as overseas.
