If you are sick, stay home. Maintain good hygiene especially at Mass and parish gatherings. Sneeze into a tissue. Dispose of tissue right away in a waste bin. Wash or purify hands right away. Do not touch your face, especially your eyes, nose or mouth. Most germs spread by hand contact. Receiving on the tongue will not spread germs, except if everyone’s tongue were touched. You are more likely to contract germs through your hands. There are hand sanitizers at the entrance of the Church for your use.
