The numbers of infected among cops, firefighters and MBTA employees is growing — but they’re confident they’ll figure out a way to push through and handle the upcoming coronavirus peak.

As of Friday afternoon, 124 firefighters in the Professional Fire Fighters of Massachusetts union had tested positive and 561 are in quarantine, union President Richard MacKinnon Jr. told the Herald.

That’s up from 62 members who’d tested positive by the end of last week, and a mere eight the previous week.

“It’s going up anywhere between 5% to 8% a day, on average,” MacKinnon said.

He said 1,018 firefighters have been tested, and there have been 2,215 documented exposures with people who potentially have the virus.

“When you do initiate 911 and you suspect that you either have it or you know that someone in your family or home has it, please let the dispatchers know,” MacKinnon asked of the public.

Health experts and local officials say the numbers will peak in the coming weeks — an eventuality MacKinnon says the firefighters of Massachusetts will deal with one way or another.

“We’ll make it work, whether we have to work overtime, or what,” MacKinnon said.

Chelsea Police Chief Brian Kyes, president of the Massachusetts Major City Chiefs of Police, said much the same.

“It’s all hands on deck,” Kyes said, adding that departments are pulling in all plainclothes officers for patrol duty and canceling time off. He said many departments are having officers avoid coming into stations, and he’s hearing about departments getting creative with scheduling to try to conserve as many officers as possible.

“I hope to God we’re getting close to the top, and then we start to walk down the stairs backwards,” Kyes said. “I’m hearing a lot of ‘Oh my God’ out there, but I’m not there yet.”

In the 40 major-city police departments around the state, 160 cops have tested positive and another 200 are quarantined, Kyes said.

That’s up from 100 positive tests and 180 quarantined, as of a week ago, and only a handful of officers in the major-city departments testing positive a week before that.

And T spokesman Joe Pesaturo said, ​”The MBTA has 63 active cases, which include 35 bus operators, three subway motor persons and three trolley motor persons. Additionally, five employees recovered after testing positive and one employee passed away.”
