NEW YORK - All essential city workers must now wear face coverings when interacting with the public.

The city is also expanding testing sites to five city Health and Hospitals locations.

Those are at East New York in Brooklyn, Morissania in the Bronx, Harlem in Manhattan, Jamaica in Queens, and Clifton on Staten Island.

It's not clear exactly when those sites will be open. 

Mayor de Blasio says 500 non-clinical staffers will be hired by the city's public hospital system. 

"Join a team of heroes, help out in our hospitals fighting back the coronavirus and saving lives. Right away health and hospitals will be hiring 500 non-clinical staff. so not medical staff. Folks who can help transport patients, who can work on the clerical team, who can help the hospitals running. The criticial work including cleaning and maintenance," De Blasio said.

The city is asking the federal government for test kits to administer more than 100,000 individual tests.

The city has enough personal protective equipment right now, but will need more in the coming weeks.

Meantime, essential employers across the state are being ordered to provide workers with face coverings, free of charge. 

Governor Andrew Cuomo announced the executive order in a briefing in Albany on Sunday. 

A second executive order expands the amount of people who can conduct antibody testing.

Antibody tests can tell whether you previously had the virus and fought it off. 

Some health experts have speculated antibody testing could be key to reopening businesses.

"Big question for everyone is when do we reopen? People want to get on with their lives. We need to be smart in the way we reopen. What does smart mean? It means a coordinated approach, a regional approach and a safe approach. Nobody wants to pick between a public health strategy and an economic strategy," Cuomo said.

The governor is also calling on the federal government to provide $500 billion in aid for state governments to help with budget shortfalls.

The governor says the federal CARES Act had zero funding to offset state revenue lost because of the pandemic. 

Statewide, Cuomo says hospitalizations are starting to decline. Still, 758 people died Saturday, marking the sixth consecutive day of at least 700 New Yorkers lost to the virus.
