The new hygiene rules, being implemented by the Catholic Church and the Church of England, are designed to reduce the risk of a mass summer outbreak of the virus.
They are being introduced following advice from the Catholic Diocese of Portsmouth and the Archbishops of Canterbury and York. Churches across Britain are also introducing the new regulations.
From this weekend, Catholic churchgoers in Jersey will be asked not to shake hands during the sign of peace and instead place their own hands together, turn to their neighbours and say: ‘Peace be with you.’
So far, 50 Islanders have been affected by swine flu since the virus spread to Jersey in June. A flu helpline is available on 445566 between 8.30 am and 5.30 pm from Monday to Friday.
