When it comes to stopping the spread of COVID‑19, advice from health experts is clear: Wash your hands. Practice social distancing. Wear a mask.
Of these three recommendations, the easiest to enforce is face masks. That’s why governments around the world, from international leaders to local mayors, have implemented mask mandates. For instance, the Illinois Department of Health states that anyone over two years of age must wear a covering over their nose and mouth in public places.
