Follow these tips to avoid getting sick or spreading illness to others while traveling:
• Wash your hands often, especially before eating.
• If soap and water aren’t available, clean hands with hand sanitizer (containing at least 60% alcohol).
• Don’t touch your eyes, nose, or mouth. If you need to touch your face, make sure your hands are clean.
• Cover your mouth and nose with a tissue or your sleeve (not your hands) when coughing or sneezing.
• Try to avoid contact with people who are sick.
• If you are sick, stay home or in your hotel room, unless you need medical care.
