An issue that worries many people when going on a cruise, especially those who travel with children, or are long journeys is What happens if i get sick? Clearly solving your question, I will tell you that Ships with more than 100 crew members on an international voyage lasting three or more days are required to have a medical service, according to international law. Here you have an article that explains it to you.
It is very important when going on a cruise, and not falling ill, to be aware of the time of year in which it is done, duration of the trip, activities and stopovers that are going to be made.
In general terms, cruises usually carry 2 doctors and twice as many nurses, with a small office set up to attend to emergencies, stabilize a patient and if necessary prepare him for a medical evacuation.
But for larger ships, like the Queen Mary 2 of Cunard Line, has for its 4.344 passengers: a surgeon, a clinical doctor and a staff of 6 nurses and two nurses. On the other hand, the Carnival Sensation for 3.514 tourists has only 1 clinical doctor and 2 nurses.
Usually the health problems that occur most during a cruise are the worsening of pre-existing diseases, intestinal or respiratory diseases, that's why always It is important to bring the treatment you are taking and the medications in their original containers. Besides, there are dental emergencies, or dizziness and vomiting, which for some people are very common on the high seas.
When you go on a cruise It is convenient to get medical insurance, because if you do not have them, the shipping company will charge you for medical services. The price of consultations on board a vehicle usually varies between 40 and 90 euros, depending on the schedule and conditions of service. Note that buying drugs on the ship without a prescription from the doctor himself is impossible. If you have insurance, what usually happens is that you pay for the service first, and then the insurance pays you back.
