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.
