Rhode Island Gov. Gina Raimondo said her state "cannot move forward to phase four" due to the spread of coronavirus from parties.
She said contacting tracing shows "we're partying too much, social gatherings are too large," during a weekly coronavirus briefing on Wednesday.
Raimondo announced Rhode Island will remain in phase three for another month, with a change; social gathering limits will be lowered from 25 to 15 people.
"We have cases traced back to a house party, with more than 50 people, and no one wearing a mask," she said.
The governor's listing of other gatherings with Covid-19 cases included a baby shower, several a large birthday parties and pool parties.
"In each of these instances, the patterns are exactly the same, people who know each other, friends and family, more than 25 people, not wearing masks, in close contact for hours," Raimondo said. There have been up to seven to 10 cases found for each of the parties, in some cases, she said.
Raimondo pleaded for residents "to knock it off, because people are getting sick people are dying, and it's unnecessary."
