A Ship Doctor is a medical professional responsible for the health and well-being of passengers and crew aboard a ship, such as a cruise liner or cargo vessel. They provide routine medical care, treat emergencies, and stabilize patients in serious conditions until they can be transferred to a hospital if needed. Ship Doctors typically work in an onboard medical facility with nurses and other healthcare staff. Their duties include diagnosing illnesses, administering treatments, and handling medical emergencies like injuries, infections, and seasickness. They must be prepared to work long hours and handle a wide range of medical cases in a remote setting.
