See full answer You may have been exposed to COVID-19 on your travels. You may feel well and not have any symptoms, but you can be contagious without symptoms and spread the virus to others. You and your travel companions (including children) pose a risk to your family, friends, and community for 14 days after you were exposed to the virus. Regardless of where you traveled or what you did during your trip, take these actions to protect others from getting sick after you return: When around others, stay at least 6 feet (about 2 arms' length) from other people who are not from your household. Wear a mask to keep your nose and mouth covered when you are outside of your home. Wash your hands often or use hand sanitizer (with at least 60% alcohol).
