Dozens of Long Island residents are being monitored for potential exposure to the deadly coronavirus, health officials announced Wednesday.

Eighty-three Nassau County residents have been asked to undergo a two-week voluntary quarantine from the date that they traveled to China or had contact with someone infected with the virus, news station WPVI reported.

“We’re monitoring this situation in Nassau very, very closely and have been right from the beginning to respond to any cases should they emerge in our county,” Nassau County Executive Laura Curran said at a press conference.

The group is required to report their temperature and any symptoms every day to local health officials, WPVI reported.

No one has been diagnosed with the virus, but tests for one resident are pending, officials said.

“Should someone need medical care, we’ll evaluate it and we have protocols in place to safely get them medical care,” Nassau County Department of Health Commissioner Dr. Lawrence Eisenstein said.

News of Nassau’s quarantine comes a day after federal officials warned that it’s only a matter of time before the infection spreads through local communities.

New York state hasn’t reported any cases of the coronavirus, but there have been 57 confirmed diagnoses across the US.
