An estimated 13.9% of the New Yorkers have likely had Covid-19, according to preliminary results of coronavirus antibody testing released by Gov. Andrew Cuomo on Thursday.

The state randomly tested 3,000 people at grocery stores and shopping locations across 19 counties in 40 localities to see if they had the antibodies to fight the coronavirus, indicating they have had the virus and recovered from it, Cuomo said.

With more than 19.4 million residents, according to U.S. Census data, the preliminary results indicate that at least 2.7 million New Yorkers have been infected with Covid-19.

The results differed across the state with the largest concentration of positive antibody tests found in New York City at 21.2%. On Long Island, 16.7% of the people tested were positive and in Westchester and Rockland counties, 11.7% of the tests were positive. Westchester County is where the state's first major outbreak originated. The Covid-19 pandemic across the rest of the state is relatively contained with just 3.6% of positive test results.

"What we found so far is that the statewide number is 13.9% tested positive for having the antibodies," he said. "They were infected three weeks ago, four weeks ago, five weeks ago, six weeks ago, but they had the virus, they developed the antibodies and they are now recovered."
