That's why some countries in Asia and Europe have ordered all citizens to wear facial protection at all times, at least while in public. It might be home-made, it might be a pollution mask. Anything that would block or at least minimise droplet transmition, because that's how the virus is spreading in most cases.
Whenever we talk, we exhale droplets that land on surfaces or other people – reducing that is considered a good practices in places as far apart as South Korea and Czechia. No-one is certainly discouraged from wearing facial protection, please also check your local authority guidelines in this respect regularly as they may change nearly on a day-to-day basis with the dynamic situation.
And one crucial thing to remember: wearing a mask, even the best N95 protection, should in no way make you drop all other suggested measures, like frequently washing your hands, avoiding touching your face or leaving home more frequently than you have to. Social distancing is still strongly advised and might be legally enforced where you live.
