The first thing you need to know about face covering is that they work in both ways: They protect other people from you more than they protect you from the environment. Wearing face coverings helps reduce the virus’s spread especially where social distancing measures are hard to maintain (e.g., supermarkets and pharmacies). So you might consider wearing a face covering or at least carrying one.
Another thing that you should keep in mind is that masks are only really effective if used properly. If done in an incorrect way, taking on and off a mask can increase your hand-to-mouth exposure, therefore cause risks. So if you are opting for any kind of face coverings, make sure you use them properly.
Keep this in mind: Measures such as wearing a face covering and avoiding high-surfaces are not sufficient enough if you are not washing your hands, maintaining social distance or remaining at home if unwell. You should approach it in a comprehensive way to protect yourself, your loved ones and your community.
