TERRE HAUTE, Ind. — A western Indiana order of nuns is facing a COVID-19 outbreak that has killed two sisters and two residents at a long-term care unit on the order’s campus, a spokesman says.

The precise number of COVID-19 cases at the Sisters of Providence of St. Mary-of-the-Woods was not available Wednesday, said spokesman Jason Moon. But all sisters and residents in long-term care at Providence Health Care who have tested positive are in isolation, he told the Tribune-Star.

Moon said two sisters have died from complications of COVID-19, as have two residents in the long-term care unit at the healthcare center, which is open to local residents in need of long-term care or rehabilitation.

The COVID-19 outbreak at the Catholic congregation of nearly 250 women just northwest of Terre Haute is the latest across the nation reported at convents and other religious orders.

All sisters who live at the healthcare center recently received the first dose of Moderna’s coronavirus vaccine and are scheduled to get the second shot next week.

“We ask that people continue to pray for all people who have been afflicted with this virus and affected by the pandemic,” the order said in a statement.

The order was founded in 1840 by Mother Theodore Guerin, who traveled from her native France to what was then Indiana’s wilderness. Pope Benedict XVI named Guerin a saint in 2006.
