CLIFTON PARK — Members of a Clifton Park health club were informed late Tuesday that two people infected with coronavirus had been to the club last Thursday and participated in a spin class.

The couple, under mandatory quarantine, has been cooperative and are helping health officials determine who they had contact with. Many of the people that they had direct contact with have been tested but not found to be infected by the virus.

Gov. Andrew M. Cuomo on Tuesday said that the virus has been found to survive longer on hard surfaces than anticipated. But in an email to its members on Tuesday evening, the club said that Saratoga County health officials believed the risk of infection to others at the gym was low.

"The Saratoga County Department of Health contacted VENT Fitness on March 9th to inform us of a potential exposure at the Clifton Park location," the club's email states. "They determined a group that attended a specific class were most at risk and are contacting this group of individuals directly to determine next steps. ... It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads."

William Lia Jr., president of Vent Fitness, said the club responded swiftly upon learning of the situation.

"I was very proud of our team to be able to provide accurate and transparent information to our membership about how we might be impacted by a global health crisis in less than 24 hours from being notified of the situation from the Saratoga DOH," Lia said in an email Wednesday morning.

In a briefing Tuesday at the Capitol, Cuomo said "there is a debate about how long the virus can live on a hard surface," and added that it is possible the virus can surface on a hard plastic or stainless steel surface for two or more days.

"If that’s the case that would be a significant issue as to why is may be transmitting the way it does," the governor said.

There have been no other confirmed cases of coronavirus in Saratoga County since the two people, one of them a pharmacist, were diagnosed on Saturday.

On Tuesday morning, Vent Fitness workers had posted signs throughout the gym about the steps the club is taking to clean the facility and urging members who feel ill to stay home. They also encouraged members to wash hands frequently.

Vent Fitness uses an electronic system to check members into spin and other exercise classes, which will make it easier for the club to determine who had been in the spin class with the two people later found to be infected with the virus.

The gym is encouraging staff and members to have limited contact with others at the club, increasing availability of sanitizing gels, wipes and sprays, and stepping up cleaning efforts in compliance with Centers for Disease Control Guidelines.

“The state Department of Health and Saratoga County Health Department have been in the midst of a rigorous case-contact investigation since the moment we learned of these positive cases and will continue in that diligent effort.,” said Gary Holmes, a spokesman for the state Health Department.

Cuomo on Tuesday announced that schools and other large gathering places in a one-mile radius in New Rochelle, Westchester County, where 108 people have been infected with the virus, would be shut down for two weeks beginning Thurday. His office has not said whether gyms in that area would be asked to close.
