ALBANY, N.Y. (CBSNewYork) – Gov. Andrew Cuomo said Monday that the number of statewide random antibody tests has expanded to 7,500, which reveals a better picture of the extent of coronavirusspread in New York.

Cuomo said 14.9% of those tested statewide tested positive for COVID-19 antibodies, which is up from the initial 13.9% statewide when a previous sample of 3,000 people was done on April 22. Cuomo said the 1% increase is statistically in the margin of error.

Regionally, the results suggest:

• 24.7% positive in New York City
• 15.1% positive in Westchester/Rockland
• 14.4% positive on Long Island
• 3.2% positive in the rest of the state

The governor said he’s going to conduct antibody surveys of 1,000 NYPD and FDNY personnel to determine the infection rate in those organizations. A similar survey will be done with 3,000 health care workers and 1,000 transit workers.
