Sick people don't stay confined to one area, they travel to different counties on an airline or cruise line, spreading their illnesses to other passengers. When sick people are on board they can spread their diseases even with just a mild but sometimes deadly cough or sneeze, they will spread their disease. New diseases can spread internationally through travel, if cruise lines and airlines show restrictions they could prevent innocents from dying from an epidemic. Most airlines like British Airlines have certified doctors to work and treat patients for access on board the plane. There are many experts on the subject, Dr. Saldmann who wrote the book “Wash your hands!” states in its travel content topics that could help travelers fend off illnesses and maintain good hygiene "the spread of a disease occurs in the airplane cabin thus spreading it to other passengers, to their destination in words" (40).Articles that I have research I talk about my previous topics, for an example on the article entitled “Too Sick to Travel: Who Decides?”. By Linda Bubank, New diseases can spread through international travel to other countries, for which they are not prepared. If airlines and cruise lines didn't allow sick people to travel around the world it would probably be safer. Prevent innocent people from dying. If a new disease remains tied to a country, it is its responsibility to destroy it, this method is more efficient. Have the country bound more prepared for a cure. This could prevent many people from dying and prevent the virus from getting out of hand. Most airlines have doctors who certify passengers for clearance on board. The article I intend to write informs readers about aircraft safety. For example, discussing whether the patient shows... at the center of the document... the consultant from the Travelers Health Branch of the US Centers for Disease Control and Prevention and a professor of medicine and infectious diseases from Emory University. You will suffer, your illness may last longer, and you will spread it to people around you. It's probably not the nicest thing to do to fly when you're sick, Saldmann said, noting that people seem more educated these days about how the disease works. it spreads. People don't understand that these diseases are contagious. "I was on a flight this week and had to sit next to a guy who was coughing his ass off the entire flight and it wasn't even a 1 hour flight. Lucky me, later I'll be sick as a dog with a sore throat , mild fever, and plugged sinuses and ears. Most, if not all, have traveled at some point when they were sick. Rescheduling them is also a major inconvenience to the sick passenger and the airline.
