Masks are a simple barrier to help prevent your respiratory droplets from reaching others. Studies show that masks reduce the spray of droplets when worn over the nose and mouth. You should wear a mask, even if you do not feel sick. In areas where the virus is circulating, masks should be worn when you’re in crowded settings, where you can’t be at least 1 metre from others, and in rooms with poor or unknown ventilation. It’s not always easy to determine the quality of ventilation, which depends on the rate of air change, recirculation and outdoor fresh air.
