The White House’s Office for Faith-based and Neighborhood Partnerships and the Department of Health and Human Services has released a guide to help houses of worship prevent the spread of the H1N1 flu. It is available online and as a printable pdf.
Perhaps the most relevant section for Episcopalians:
Many religious services and community meetings involve a time of greeting or recognition –by shaking hands or hugging. Encouraging interaction without physical contact and implementing social distancing measures may reduce the spread of flu in your community.
Some religious traditions and rituals emphasize eating and drinking from communal dishes –and vessels. Flu transmission may be possible in these circumstances. If flu is circulating widely in your community, faith and community leaders may consider adjusting such practices in order to reduce the spread of flu.
