CHAPPAQUA, New York (WABC) -- New York State's Department of Health is investigating the potential COVID-19 exposure at a high school graduation ceremony in Westchester County.
The individual, who had recently traveled to Florida, attended the Horace Greeley High School drive-in graduation ceremony held on June 20 at Chappaqua Train Station and subsequently began showing symptoms, testing positive for coronavirus.
Since then, officials say four more individuals who attended the ceremony and had contact with the first positive case have also tested positive.
Officials say all individuals who have tested positive are currently self-isolating. In addition to the graduation ceremony, the student participated in a non-school related "Field Night" event on June 20, which was also attended by juniors and seniors and students from surrounding school districts.
Individuals who attended the graduation ceremony, Field Night event, or events associated with graduation, which continued into June 21, should extend their quarantine period until July 5th.
Chappaqua Central School District tweeted out photos of the drive-in high school graduation, where 343 seniors graduated.
Even Bill and Hillary Clinton had a video message congratulating Class of 2020, which is described as a "message from two of your neighbors."
The New York State Department of Health and the Westchester County Health Department are working with officials from Horace Greeley to identify all individuals who attended the graduation ceremony and any subsequent gatherings where they may have been exposed. The New York State Contact Tracing Program will be reaching out to identified individuals and anyone who attended the ceremony or subsequent gatherings should get tested.
On June 14, New York State DOH issued guidance to ensure any district that decides to host a graduation ceremony adheres to appropriate protective measures including social distancing, limitations on number of attendees, wearing face coverings, and other precautions. Part of the comprehensive public health response will be to determine whether the guidance had been followed.
As part of their public health outreach, the State and County DOH encourage testing for anybody who attended the graduation ceremony or the Field Night event and may have come in contact with an infected individual.
A Tri-State travel quarantine was announced by Cuomo on June 18, including New Yorkers returning home from elsewhere.
Right now travelers from eight states are required to quarantine for 14 days if they come to New York, New Jersey or Connecticut.
Those states are Alabama, Arkansas, Arizona, Florida, North Carolina, South Carolina, Utah and Texas.

The governor also issued a new executive order that makes New York employees who voluntarily travel to high-risk states after June 25 ineligible for COVID-19 paid sick leave.
"New Yorkers have controlled the spread of this unprecedented virus by being smart and disciplined, and our progress to date is illustrated by the current low numbers of new cases and hospitalizations," Cuomo said. "But as we are seeing in other states who reopened quickly, the pandemic is far from over and we need stay vigilant. We're prepared to do the aggressive testing and contact tracing required to slow and ultimately control any potential clusters of new cases like the one in Westchester County. If we are going to maintain the progress we've seen, we need everyone to take personal responsibility - that's why I'm issuing an executive order that says any New York employee who voluntarily travels to a high-risk state will not be eligible for the COVID protections we created under paid sick leave."
