If you are feeling ill or think you may have been exposed to a virus, you should refrain from coming to Mass or parish events. In the same way, if you have a cold you should refrain from offering your hand to others at the sign of peace. Simply gently bow your head with your hands kept together and acknowledge those around you while saying “Peace be with you.” Likewise if you are not comfortable sharing the sign of peace either because your doctor has indicated you are currently more susceptible to illness or those around you seem ill you should feel no pressure to do so. Finally, The obligation to attend Mass on Sunday and other Holy Days of Obligation is the ordinary expectation for Roman Catholics (Canon 1247). However, extraordinary circumstances such as sickness or severe weather excuse the faithful from this obligation. If you suspect you have the flu or are suffering from a serious cold or other contagious illness, please stay at home and do not risk spreading infection to others.
