The Nassau County (New York) Department of Health has confirmed a case of Hepatitis A virus in an employee at Jersey Mike’s Subs located at the 24 Atlantic Avenue, Oceanside, New York location. Health officials have alerted customers who visited the store between April 5, 2025, and April 19, 2025, about potential exposure to the virus.
Customers who consumed food or beverages prepared on-site or used the restrooms during this period may have been exposed, although health officials note the risk of transmission is considered low. Those potentially exposed are advised to consult with their healthcare providers about appropriate next steps.
Postexposure treatment is effective if administered within 14 days of exposure. Persons falling within this timeframe should seek medical advice and treatment promptly. Individuals outside the treatment window should monitor for symptoms and discuss vaccination options with their healthcare providers for future protection.
Those who have previously received two doses of the Hepatitis A vaccine or have had the illness in the past are considered protected and require no further action.
The Nassau County Department of Health has established a call center at 516-227-9651 for individuals seeking additional information. The center will operate this weekend from 10:00 am to 2:00 pm local time.
Hepatitis A is transmitted through the consumption of food or drink handled by an infected person or through contact with objects contaminated with the stool of an infected person. The virus causes liver inflammation with symptoms that typically appear within 28 days of exposure, though the range can be 15-50 days.
Symptoms include fever, fatigue, poor appetite, nausea, stomach pain, dark-colored urine, and jaundice, which presents as yellowing of the skin and whites of the eyes. While there are no specific medications to treat Hepatitis A after symptoms develop, the disease is rarely fatal, and most patients recover within weeks without complications.
Health officials emphasize that thorough hand washing after bathroom use and before, during, and after food preparation remains the most effective preventive measure against Hepatitis A and similar intestinal illnesses. They also advise against sharing food and utensils, especially when someone is sick.
Commenting on this article, the nation’s leading Hepatitis A lawyer said, “Any one who is not already immune, and are still within the two week exposure window, should get themselves vaccinated immediately to reduce their risk of additional complications.”
