Rising Infections: A Six-Month Snapshot
Through June 2025, Italy has recorded 247 cases of hepatitis A, a substantial jump from the 159 cases reported during the same period in 2024 and the 105 cases documented in 2023. The regions most impacted by this surge are Lombardy, Emilia-Romagna, and Lazio. Health authorities are closely monitoring the situation to understand the factors driving this increase.
Demographic Trends and Risk Factors
The illness disproportionately affects men, accounting for 64% of reported cases. The most frequently affected age group falls between 35 and 54 years old, with a median age of 37. Notably, 29 cases have been identified in pediatric patients, highlighting the broad reach of the outbreak.
Investigations have identified several common risk factors associated with infection. Consumption of seafood is linked to 47.1% of cases, while travel to areas where hepatitis A is endemic accounts for 23%. Consumption of berries is also a contributing factor in 24% of cases.
Concerning Increase Among Men Who Have Sex With Men
A particularly worrying trend is the marked increase in hepatitis A cases among men who have sex with men (MSM). The proportion of cases within this demographic has nearly tripled, rising from 11.4% in 2024 to 29.8% in 2025. This shift suggests a potential change in transmission dynamics and necessitates targeted public health interventions.
Public Health Response and Future Outlook
Italian health officials are urging individuals to practice preventative measures, including thorough handwashing, safe food handling, and vaccination, particularly before traveling to at-risk areas. Further investigation is underway to determine the specific strains of the virus circulating and to assess the potential role of hepatitis E in the overall picture. The continued monitoring of these trends will be crucial in mitigating the spread of infection and protecting public health.
