PORTLAND, Maine (AP) — At least seven people have died in connection to a coronavirus outbreak that continues to sicken people in Maine following a wedding reception held over the summer that violated state virus guidelines, public health authorities said.

The August wedding reception at the Big Moose Inn in Millinocket is linked to more than 175 confirmed cases of the virus, the Maine Center for Disease Control and Prevention said Tuesday.

Maine authorities have identified overlaps between the wedding reception and outbreaks elsewhere in the state. An employee of the York County Jail attended the wedding, Maine CDC officials have said. Maine health officials have also said a staff member from a Madison rehabilitation center, which is the site of six of the seven deaths, attended the event.

The virus cases stemming from the wedding have spanned hundreds of miles in a state that had largely controlled the spread of the coronavirus through the summer. Maine has reported less than 5,000 cases of the virus in total since March.

But the growing number of cases related to the wedding, which exceeded the state’s guidelines of 50 people or less at indoor gatherings, could undo some of that progress if it continues to swell. Authorities have said more than 65 people attended the wedding.

The six people from the Madison rehabilitation facility who died were all residents of that facility and none of them attended the wedding reception, said Nirav Shah, director of Maine CDC.
