After a person who attended an in-person religious service on Mother’s Day tested positive for the novel coronavirus, public health officials in Butte County issued a strongly worded warning to residents not to speed too quickly through the reopening process.

The person received a positive test result the day after the service, which had more than 180 attendees, officials said Friday in a news release.

Gatherings of any size remain prohibited, even in counties that are reopening more quickly than the rest of California. But the organization that held the service chose to open its doors despite the rules, exposing the entire congregation to the coronavirus, officials said.
