(CNN) New York Gov. Andrew Cuomo plans to deploy the National Guard and create a 1-mile containment area in New Rochelle in an attempt to stop a growing cluster of coronavirus cases.

New Rochelle, a suburb of New York City located in Westchester County, has had 108 cases of coronavirus, Cuomo said, making it probably the largest cluster of coronavirus cases in the United States. New Rochelle makes up a majority of the state's 173 coronavirus cases and has double the number of cases as New York City.

"New Rochelle is a particular problem," Cuomo said. "It is what they call a cluster. The numbers have been going up, the numbers have continued to go up, the numbers are going up unabated, and we do need a special public health strategy for New Rochelle."

The containment zone surrounds a synagogue believed to be the epicenter of the outbreak. A man who lives in New Rochelle , works in Manhattan and attends the synagogue tested positive for the virus last week. The man's 20-year-old son attends Yeshiva University in Manhattan, and his 14-year-old daughter attends SAR Academy and High School in the Bronx.

Cuomo and Health Commissioner Dr. Howard Zucker said that the containment area will be a concentric circle with a 1-mile radius because contagious viruses generally spread geographically.
