A focus of the O.A.S.I.S. Clinic is attending to the healthcare and psychosocial needs of persons infected with hepatitis C (HCV), and residing in the greater East Bay community. We participate in a number of collaborations with Bay Area, Southern California, West Coast, other US urban area partners, as well as the National Institute for Drug Abuse (NIDA), the Health Resources Services Adminstration (HRSA), and the Centers for Disease Control and Prevention (CDC).
