<prompt> Human: This is probably something that many people dont think of when they travel to another country and I havent found any really useful information about this.I am an American and my grandma and grandpawho live in Russia are going to be arriving to the U.S. in mid November and are only going to leave by the beginning of March. I know of the horror stories of tourists travelling to America then getting sick and having to stay at the hospital for 1 day only to get a 20k bill. I want to avoid that but I dont know how. Is there some kind of insurance I can buy that will help in case of emergencies? If not what can I do in case they get sick.  <response>: They can purchase travel insurance through a company like Alianz.
