New York Gov. Andrew Cuomo has deployed the National Guard to New Rochelle, a coronavirus hot spot just north of New York City. "This is unique in the United States of America, we haven't seen this anywhere else. Think about it, New Rochelle has double the cases of New York City, it's true, it's a phenomenon," Cuomo told reporters Tuesday in announcing the deployment. Westchester County, where New Rochelle is located, had 108 COVID-19 cases out of the 173 confirmed infections across the state, according to state health department data Tuesday.

Cuomo compared the number of cases in New York to Washington state, where officials said an outbreak has spread to at least 162 people, killing 22 mostly elderly residents. Across the U.S., at least 25 people have died, but none in New York so far. A man in his 60s died from COVID-19 in Bergen County, New Jersey, state officials confirmed Monday. Fourteen New Yorkers are hospitalized with COVID-19, Cuomo said, adding "most of the 14 are members of that vulnerable community."
