New York Gov. Andrew Cuomo revealed Thursday that preliminary results from a coronavirus antibody study show the statewide infection rate is 13.9 percent, which would mean around 2.7 million residents could have carried the disease.

The 3,000 samples were collected from 40 sites in 19 counties, according to Cuomo, and suggested the infection rate is as high as 21.2 percent in places like New York City.

“These are people who were infected and who developed the antibodies to fight the infection,” Cuomo said. “They had the virus, they developed the antibodies and they are now ‘recovered’.”

The governor says the testing was conducted at sites set up outside places like grocery and box stores.

“These are people who were out and about shopping,” Cuomo said. “They were not people who were in their home, they are not people who are isolated, they are not people who are quarantined -- who you could argue probably had a lower rate of infection because they wouldn’t come out of the house.”

Nearly 70 percent of the overall testing was done in the regions of Westchester, New York City and Long Island.

New York also reported 438 additional coronavirus deaths Thursday.
