Two Brooklyn District Attorney’s Office staffers have been told to stay home because of possible exposure to the deadly coronavirus, The Post has learned.

An internal memo to Brooklyn DA employees dated March 4 states that two of their colleagues have been instructed to stay away from the office at 350 Jay St. in Downtown Brooklyn until next week.

The employees were asked to remain home “because of their recent presence at locations in New York State, where an individual who is currently hospitalized with coronavirus was also present,” according to a copy of the memo obtained by The Post.

The memo states that the employees and their families remain free of coronavirus symptoms — and that no Brooklyn DA staffer has tested positive for the virus.

There are more than 500 employees at the Brooklyn DA’s office.

Sources within the DA’s office said that the memo has raised concerns about steps taken to prepare for the outbreak.

“We only got this update of basic measures with such a serious situation,” one prosecutor told The Post.

On Wednesday, sources told The Post that the Brooklyn Civil Court building at 141 Livingston St. was given a thorough disinfecting after learning that an attorney who passed through there goes to the same synagogue as Lawrence Garbuz — a lawyer and New Rochelle resident who is the second confirmed case of coronavirus in New York.

Garbuz’s wife and two children have also tested positive for the virus.

As of Thursday morning, there were four confirmed coronavirus cases in New York City, and 18 others in Westchester County, News 12 reports.

A spokesman from the Brooklyn DA’s office declined to comment further on the memo.
