A total of 23 MTA employees have tested positive for the coronavirus, the agency announced Thursday.

The batch of positive tests include 19 employees of New York City Transit, which runs the city’s buses and subways, and four Long Island Rail Road workers.

Agency Chairman Pat Foye said all 23 employees “are in quarantine or receiving appropriate care.”

“As we have said, this is not unexpected as testing continues to ramp up, which will help contain the spread of the virus,” Foye said in a statement.

“The MTA is working closely with the state Department of Health to identify any colleagues who come in contact with employees who are confirmed, send them home to self-quarantine, provide access to necessary testing and immediately and aggressively disinfect the workplace,” he said.

The agency did not provide any further details on the coronavirus patients.

Foye and Gov. Andrew Cuomo have insisted transit must remain open through the coronavirus crisis to transport medical personnel and other essential workers to and from work.

The MTA has said it is cleaning trains and buses every 72 hours and commonly-touched station surfaces twice daily.

Despite that, transit workers and riders alike have expressed fears about catching the virus in MTA facilities.

Transport Workers Union Local 100, which said its members account for 12 of the New York City Transit cases, has called on the MTA to provide COVID-19 tests for any workers that show symptoms or come into contact with those who do.

“What TWU Local 100 members are doing is nothing short of heroic,” union president Tony Utano said in a statement. “There is a lot of concern and even fear out there but they are doing their jobs.”
