A staff member at Cedar Dell assisted living facility tested positive for coronavirus this week as the number of Covid-19 cases in Dartmouth hit 275 on May 15, with 29 deaths in town, according to a Board of Health press release.

Just under half of the cases (132, or 48 percent) come from congregate living facilities like nursing homes and assisted living, the press release noted.

According to Public Information Officer Kyle Costa, the numbers are “consistent with what’s going on nationally.”

Around 80 percent of the fatalities were residents of congregate living facilities, he said. “It’s the older generation that’s unfortunately been hit really hard by this.”

Even so, Costa noted, “This area in particular has done an amazing job staying on top of things...I think it’s a credit to everybody who’s listening to recommendations.”

He added that people should remain cautious and continue to follow state and CDC guidelines recommending regular hand washing, social distancing, and wearing a face covering in public.

“There could be an uptick, a second surge,” he said. “Being overly cautious is better than being not being cautious enough. That’s the position that we’ve taken from day one and we’re gonna continue to do that until we beat this thing.”

Meanwhile, Cedar Dell spokesperson Ted Doyle stated that the staff member is the first person to test positive at the facility. “We’ve been very fortunate,” he said.

The associate was last in the community on May 2, he noted, and they’ve been keeping an eye on those who had contact.

“It’s been over two weeks now,” he said. “We’re very confident that they’ve been distanced and not impacting other people in the community.”

The staffer is doing fine and is resting at home with mild symptoms, Doyle added. They will stay at home until medically cleared to come back.

There are 87,052 confirmed cases of Covid-19 in Massachusetts as of May 18, with 5,996 in Bristol County. 5,862 people have died of the illness in the state.
