If you want to know why public health officials are so nervous about how much worse the COVID-19 pandemic will get as the holiday season unfolds, consider what happened after a single, smallish wedding reception that took place this summer in rural Maine.

Only 55 people attended the Aug. 7 reception at the Big Moose Inn in Millinocket. But one of those guests arrived with a coronavirus infection. Over the next 38 days, the virus spread to 176 other people. Seven of them died.

None of the victims who lost their lives had attended the party.
