DALLAS (CBSDFW.COM) – Four Dallas ISD police officers have been infected with the coronavirus, officials said Monday, and at least one of them has been hospitalized.

During a news conference Monday morning, Superintendent Dr. Michael Hinojosa said there are four total Dallas ISD officers who tested positive for COVID-19.

Earlier in the morning, Chief Bill Avera of Jacksonville ISD (just south of Tyler, Texas) said on Twitter that a sergeant with the Dallas ISD Police Department, whose first name is Vince, tested positive and was admitted to the hospital.

“[Praying emojis] for this warrior and first responder please. He is definitely one of the good guys!” Avera said.

The conditions of the other three officers are not known at this time.

During the news conference, Hinojosa said one of the officers is “not doing well,” but it is unclear which officer he was referring to.

As of Sunday, there are currently over 1,100 confirmed cases of the coronavirus in Dallas County.
