There are a couple of ways to go here. The school used to send out information about an organization that specializes in health insurance for students studying abroad. That's what I got. It was reasonably priced, even for me as an antiquarian medical student. The actual cost varies by age and whether there are any preexisting medical conditions. Some folks were able to go on their parents' or partners' insurance, but if you plan to do so, make absolutely sure that you will be covered out of the country because a majority of health plans will NOT cover you. Also, whatever plan you get, try and get one that covers repatriation expenses if you require it (do you really want to be treated in St Maarten for a major illness or trauma? -- I don't think so -- and getting back to the States by air ambulance ain't cheap). Nagico insurance on the island can give you a health insurance policy for about $200 per year, but it will not cover repatriation. Do realize that if you are on the island and require medical attention that you will not be able to leave the island until you have paid your bill or made acceptible arrangements to do so -- usually a $5000 downpayment will suffice.
