Koh Tao as of July 2017 has a new purpose built government hospital, which can be found in Mae Haad. The hospital can cator for most problems a local or tourist may incur. You will find everything you would expect at the new hospital with helpful nurses and doctors on hand for any occurance. This being said Koh Tao still does not have a diving physician or hyper baric chamber, if these are needed then the patient is evacuated to Koh Samui for treatment. You will find the price for treatment and medications lower than the prices in the local clinics.
