Twenty police officers and 10 firefighters in Mobile have tested positive for carrying the antibodies of COVID-19, according to officials.

All 30 of those first responders are now awaiting for the return of nasal swab tests to return from Birmingham-based Assurance Scientific Laboratories. Those tests will determine if the police officer or firefighters are contagious and should quarantine for 14 days.

James Barber, the city’s executive director of public safety, said that close to two-thirds of the city’s first responders have been screened, or roughly 600 people.

Barber said of the 30 quarantined, only one has shown physical signs of having coronavirus. But none of the nasal swab tests have been returned. The city began the testing Monday.

“Some of the (tests) are coming back 24-48 hours and some are coming back in six days,” said Barber. “None of the first responders we can confirm have the coronavirus. We can only confirm the rapid tests of (first responders) who have the antibodies for COVID-19.”

Barber said the police officers and firefighters were the first to be tested at Mobile’s Ladd-Peebles Stadium, which has been set up for drive-through coronavirus testing.

Mobile County had 69 confirmed cases of coronavirus as of Thursday evening, according to the Alabama Department of Public Health.

In addition, the Mobile County Sheriff’s Department is reporting at least two positive cases of coronavirus within its corrections unit. An inmate at the Mobile Metro Jail has also tested positive. Mobile has reported three deaths.

Mobile Mayor Sandy Stimpson, meanwhile, said no decisions have been made on whether the city will provide hazardous duty pay for its first responders who come in contact with the public on a frequent basis. The Mobile County Sheriff’s Department, in a report to a local TV station, confirmed it was offering “time-and-a-half” hazardous duty pay to its corrections officers and sheriff’s deputies.

Hazardous duty pay is additional pay beyond a first responder’s base salary for performing an essential job in a dangerous situation.

Stimpson said he should have a decision soon on whether police and firefighters will be offered a similar benefit.

“When the county makes a recommendation to do hazardous pay, it’s within the Sheriff’s Department and that’s a very well-defined group of people within their organization,” Stimpson said. “When we talk about hazardous pay, we’re talking about 900 first responders. It also throws out the question about sanitation workers. And that all needs to be looked at. You can’t do that on the back of a match book. It takes a lot of calculations to do that.”

Stimpson said the city could fund the additional payout through the city’s rainy day fund, but he said there are concerns over when the benefit would end.

“When there is hazardous pay given, it’s usually given over a finite period of time such as during a hurricane,” said Stimpson. “But it ends. If you were to hypothetically pay everyone in the city hazardous duty pay, you’ll run out of money faster. Then what will you do? Yes, we can do this but how does it impact everything? We have to be able to come out of the other side of (the pandemic) strong and not handicapped.”
