From yesterday's New York Post:
An unidentified person who handled the communion wafers could have transmitted the illness to parishioners at two Masses on the holy day, authorities said.
The possible spread of the virus occurred at Our Lady of Lourdes Roman Catholic Church in Massapequa at the 10:30 a.m. and noon Masses on Dec. 25.
The Nassau County Department of Health said anyone who received the bread wafers should report for inoculation at the church this week. A department spokesman declined to provide details, citing privacy concerns.
"Individuals may be at risk," said Sean Dolan, a spokesman for Diocese of Rockville Centre.
