During flu season parishes may receive requests from parishioners to make changes to the liturgical celebration in order to prevent the spread of the flu and other viruses.
The United States Conferences of Catholic Bishops, in consultation with the Center for Disease Control, recommends that the following measures be taken in the celebration of the liturgy:
a) Priests, deacons, and extraordinary ministers of Holy Communion should be especially reminded of the need to practice good hygiene. Ministers of Holy Communion should be encouraged to wash their hands before Mass begins, or even to use alcohol based anti-bacterial solution before and after distributing Holy Communion.
b) Pastors should instruct people who feel ill not to receive from the cup.
c) The Diocesan Bishop should always be consulted regarding any changes or restriction of options in the celebration of Roman Catholic Liturgy. However, the need for the introduction of widespread liturgical adaptations for the prevention of the transmission of influenza in the dioceses of the United States of America is not evident at this time.
