The goal of this observational study is to assess the effectiveness of targeted screening for Hepatitis B (HBV) and Hepatitis C (HCV) infections in adults aged 18 to 50 from the Chinese community residing in Milan.

The main questions it aims to answer are:

• Does community-based, culturally sensitive screening increase the detection of undiagnosed HBV and HCV infections in this high-risk population?
• What is the level of adherence, satisfaction and awareness regarding rapid testing methods in this community?

Participants will:

• Receive pre-test counseling in Italian or Chinese with the help of an interpreter
• Complete a brief, anonymous questionnaire on demographics, risk factors and awareness of HBV/HCV
• Undergo capillary rapid testing for HBV and/or HCV
• Receive test results during the same visit
• Complete a short post-test satisfaction questionnaire

The study will be conducted in public spaces within Milan's Chinatown, during monthly sessions, until 1,000 participants are enrolled. Each session will last approximately 30-60 minutes per participant.
