Coughing or sneezing openly spreads germs into the air and onto surfaces, putting others at risk of infection. To minimize the spread of illnesses such as flu, colds, and COVID-19, it is recommended to cover your mouth and nose with a tissue when coughing or sneezing, and then dispose of the tissue properly. If no tissue is available, using the crook of your arm is the next best option. This simple practice helps protect your family and community from contagious diseases.
