The virus has infiltrated Sunday sermons, meetings of ministers and Christian youth camps in Colorado and Missouri. It has struck churches that reopened cautiously with face masks and social distancing in the pews, as well as some that defied lockdowns and refused to heed new limits on numbers of worshipers.

Pastors and their families have tested positive, as have church ushers, front-door greeters and hundreds of churchgoers. In Texas, about 50 people contracted the virus after a pastor told congregants they could once again hug one another. In Florida, a teenage girl died last month after attending a youth party at her church.

More than 650 coronavirus cases have been linked to nearly 40 churches and religious events across the United States since the beginning of the pandemic, with many of them erupting over the last month as Americans resumed their pre-pandemic activities, according to a New York Times database.
