The HSE’s Health Protection Surveillance Centre (HPSC) have released updated COVID-19 guidance for religious services, along with a new set of guidelines specifically for “the holiday season”.

It sets out how “overcrowding” at mass or other religious services could be prevented over the Christmas period.

Recommendations included running additional services, increased stewarding of parishioners, and for churches to set up an “advance booking system where necessary” for places at services. Parishes have been successfully abiding by public health guidelines since March.

Mass should not exceed one hour, including the time it takes people to enter and exit the church, the guidance stated. There should be at least one hour between services to allow time to clean surfaces, and ventilate the church.

Due to the increased risk of Covid-19 transmission from people singing in proximity to others, the guidance stated carol singing will not be permitted at religious services.
