A popular Westchester restaurant remains closed due to a hepatitis A scare.

Westchester County health officials say that anyone who visited Winston restaurant in Mount Kisco over the Easter and Passover holidays is at risk for hepatitis A.

Health department officials confirmed an infected worker at the restaurant may have exposed customers to the virus between April 17 and May 3.

They say it's important for people to know that there's only a two-week window from the time of exposure to get preventive treatment, and that the virus can become serious if it goes untreated.

"We're really focusing on the people who ate there, who dined there on April 23, cause today is their very last day to be able to get the vaccine,” says Westchester Commissioner of Health Dr. Sherlita Amler.

Within two hours of opening, the Health Department reported over a dozen customers stopped in.

Anyone who was at Winston from April 17 through April 22 has already missed the two-week window.  Officials advise anyone who missed their two-week window to get vaccinated to contact their health care provider immediately.

The virus usually spreads by ingesting something contaminated with an infected person's stool. Symptoms include fever, fatigue, dark-colored urine, and yellowing of the skin or eyes.

Westchester County Health Department is offering free preventative treatment today through Friday. They have opened up clinics, which can be pre-registered for online.

It's unknown when it will reopen. Staff will be doing a thorough cleaning and will receive vaccinations.
