Hepatitis A Outbreaks in Chicago: Stay Protected

How Chicago's Health Department Tracks Hepatitis A

The Chicago Department of Public Health works closely with the Illinois Department of Public Health (IDPH) and the CDC to investigate Hepatitis A cases and outbreak clusters. CDPH conducts epidemiological investigations to identify exposure sources, including restaurants, food service facilities, and food products. When outbreak investigations identify specific sources, CDPH issues public health advisories and works with the FDA to coordinate recalls. Chicago's surveillance system captures case reports from healthcare providers and labs, enabling rapid response to emerging clusters. Residents can check CDPH's official website and media releases for active outbreak notifications affecting the city.

Contamination Routes: Produce, Shellfish, and Food Handlers

Hepatitis A spreads through fecal-oral transmission, commonly via contaminated produce (lettuce, berries, green onions) and raw or undercooked shellfish harvested from polluted waters. Infected food handlers with poor hand hygiene are a primary transmission risk in restaurants and food facilities; the virus survives on surfaces for hours and can contaminate ready-to-eat foods. Chicago's FDA field office and FSIS work with local establishments to enforce hand-washing protocols and food handler certification requirements. Produce sourced from regions with known Hepatitis A activity poses elevated risk, particularly during outbreak periods. Understanding these contamination routes helps residents make informed choices about produce selection and food preparation.
