The city has also opened two new testing sites in Manhattan and Brooklyn.

In Manhattan, the Highbridge Recreation Center in Washington Heights and in Brooklyn, 1223 Coney Island Ave. in Midwood.

Antibody tests will also begin for 140,000 health care workers and first responders.

The tests will be offered at hospital, firehouses, police stations and corrections facilities. Testing identifies likely past infection of COVID-19.

The testing will be a partnership with the United States Department of Health and Human Services and the CDC.

The mayor also gave an update on Pediatric Multi-system Inflammatory Syndrome in children.

The CDC released a new case definition for what is now called Multi-System Inflammatory Syndrome in Children, or MIS-C.

The CDC has also confirmed there is a link to COVID-19. The Department of Health and Mental Hygiene is currently reviewing cases reported in New York City under the CDC’s new definition. Important precautionary measures to keep children safe continues to be good hygiene, face coverings and social distancing.

Common symptoms of MIS-C include persistent fever, irritability or sluggishness, abdominal pain, diarrhea, vomiting, rash, red or pink eyes, enlarged lymph node gland on one side of the neck, red cracked lips or red tongue and swollen hands and feet.

As of Monday, the city has had 145 reports, using the initial PMIS case definition released on May 4.

The mayor says 67 of those reports tested positive for COVID-19 or antibodies, and there has been one fatality.

New York City will have an updated number of cases under the MIS-C definition later this week.

Alternate side parking is back in effect this week from May 18 to May 23 for a clean sweep citywide. Alternate side parking will be suspended on May 21 for Ascension Day.

It will be suspended again May 24 through June 7 where the Department of Sanitation will assess cleanliness.
