Jet lag — Older adults may have more severe jet lag and take longer to recover. Travelers can minimize jet lag by shifting to the local schedule as soon as possible. Travelers may be able to avoid jet lag by adjusting sleep schedules a few days before travelling.

Traveler’s diarrhea — Contaminated food or water or anxiety and jet lag can contribute to traveler’s diarrhea. It often strikes abruptly and causes four to five loose or watery bowel movements. In most cases, traveler’s diarrhea will go away in a day or two without medical treatment. Most doctors don’t recommend preventive medications such as antibiotics or bismuth subsalicylate (Pepto-Bismol), except in special circumstances. The best prevention is good hand hygiene and food and water safety. International travelers should drink only bottled beverages or liquids that have been boiled.

Motion sickness — Travellers susceptible to motion sickness should consult a physician about over-the-counter or prescription medications. Some natural remedies have been shown to reduce symptoms, too. Options include acupressure wristbands, ginger tea or dietary supplements or aromatherapy.

Altitude sickness is caused by dry air, a decrease in oxygen, and low barometric pressure when travelled to a higher altitude than you’re used to. As a result, you may have problems, such as headaches, dehydration, and shortness of breath. Some people are affected at 5,000 feet (1,524 meters), but others aren’t affected until they reach altitudes of 10,000 feet (3,048 meters) or more.

Middle East Respiratory Syndrome (MERS)-  It is viral respiratory illness first reported in Saudi Arabia in 2012. It is caused by a coronavirus called MERS-CoV. Most people who have been confirmed to have MERS-CoV infection developed severe acute respiratory illness. They had fever, cough, and shortness of breath. About half of these people died.

Point to Remember : Travellers of all ages travelling can benefit from a pre travel medical appointment, ideally four to six weeks before departure. The doctor will perform a physical exam and assess the health risks associated with travel plans.
