As of 20 March 2026, the Campania region of Italy has recorded at least 154 hepatitis A cases (+21 within 24 hours) since the beginning of the year. The increase in cases is suspected to be linked to contamination of bivalve molluscs, prompting intensified control measures across the entire bivalve supply chain.
Cotugno Hospital, the regional reference center for infectious diseases in Naples, is managing 54 hospitalized hepatitis A patients as of 22 March 2026, including eight new admissions to the emergency department on that day alone.
In response, Naples Mayor Gaetano Manfredi issued an emergency ordinance banning the consumption of raw shellfish and related molluscs in all public establishments.
