Follow the same advice that public health officials recommend for the cold and flu season: wash your hands often with soap and water, cover your mouth and nose when coughing or sneezing, avoid others who are unwell, and stay home when you are sick.
The most important thing you can do to prevent coronavirus and other illnesses is to wash your hands regularly with soap and water for about 20 seconds and avoid touching your face. When outside your home, remember to practice social distancing by keeping 2 metres from others when possible.
Cover your mouth when you cough so you're not exposing other people. If you are sick yourself, stay away from others. Contact your health-care provider ahead of time so you can be safely assessed.
