Capri and Naples Report Hepatitis A Outbreak in 2026

Campania health authorities in Italy have confirmed a significant increase in hepatitis A cases, with 133 confirmed infections reported since January 2026.

As of March 20, 2026, the outbreak, which is centered around Naples and Capri, is primarily linked to the consumption of raw or undercooked bivalve mollusks, such as mussels, clams, and oysters that have been contaminated with the hepatitis A virus.

Additionally, there is evidence suggesting possible secondary person-to-person transmission contributing to this year's outbreak.

Currently, more than 40 to 50 patients are hospitalized at Naples' Cotugno Hospital.

In response to the outbreak, local media reported Naples Mayor Gaetano Manfredi issued an emergency ordinance on March 19-20, banning the sale and consumption of raw seafood in public establishments.

Residents and tourists are urged to thoroughly cook shellfish, practice strict hand hygiene, and avoid raw seafood. Campania, located on Italy's southern coast, is a major tourism hub, attracting approximately 20 million tourists annually.

This situation highlights the recurring food safety challenges faced by international travelers in 2026.

Public health officials recommend vaccination for at-risk groups and emphasize the need for continued vigilance to prevent further spread of the virus.

When departing from the USA for international travel in 2026, hepatitis A vaccination services are offered at travel vaccine clinics.
