You are strongly advised to take out travel insurance before you visit the States, as there is no NHS in the country and medical care is prohibitively expensive.

Make sure that your insurance covers you if you intend to indulge in sporting activities - water sports, climbing, skiing etc. - and DON'T skimp if you are asked to pay an extra premium.
Note, however, that most insurers work on the basis that you will be required to pay for any on-the-spot medical treatment in the US and will only be reimbursed on your return home.

If you suffer loss or theft, make sure that you contact the local police so that they can complete an official report for presentation to your insurance company. For more details on theft, go to our Travel Advice page.
