When you do have to go out in public for an essential errand, cover your nose and mouth with a homemade mask. Be careful not to touch your eyes, nose, and mouth when removing your face covering and wash your hands immediately after removing.
WHO recommends medical masks for health workers, people with COVID-19 symptoms, caregivers, people aged 60 or over, and people with underlying health conditions. Cloth face coverings can be made at home from common materials at low cost, like old T-shirts, scarves or bandanas.
