Self-help for the traveler who becomes ill

While infections commonly occur in travelers, most can be prevented by avoiding fresh fruit (unless it is peeled), fresh vegetables, unpasteurized milk and cheeses, nonbottled water and ice; by taking antimalarial drugs; by using insect repellents in areas where indicated; and by using common sense. Remember also that travel does not prevent you from getting many of the illnesses you might get at home. It is essential to take any regular medications along with you. I recommend that you take such medications in your carry-on baggage, for airlines have a propensity for losing baggage that contains critical items. If you do become ill, you can take care of most illnesses yourself if you have planned ahead.
