Do not exercise if you have a fever, cough and difficulty breathing. Stay home and rest, seek medical attention and call in advance. Follow the directions of your local health authority.
If you are able to go for a walk or bicycle ride, always practice physical distancing and wash your hands with water and soap before you leave, when you get to where you are going, and as soon as you get home. If water and soap are not immediately available, use alcohol-based hand rub.
