In November 2018, the United States withdrew from the Joint Comprehensive Plan of Action (JCPOA), known commonly as the Iran nuclear deal, and imposed severe sanctions on Iran. This study explores the impact of US sanctions in Iran's health research system. This phenomenological study interviewed 24 Iranian health science scholars through purposeful sampling to learn about their experiences and thoughts regarding the impact of US sanctions on Iran's health research system. The impact of sanctions on Iran's health research system were classified into five categories ( ) financial issues, ( ) difficulty in supplying laboratory materials and ( ) equipment, ( ) disruption in international research collaboration and activities, and ( ) other issues (e.g., increased stress and workload). This study indicated that since research centers in Iran are highly dependent on governmental budgets, sanctions have greatly affected the health research system in Iran. Financial and economic problems, restrictions in transferring funds, and the disruption in political and international relations have created many challenges for supplying medical laboratory materials and equipment for medical and health research centers in Iran.

People who use drugs, particularly injection drug users (IDUs) are known as the major source of hepatitis C virus (HCV) infection. This study was performed to determine the prevalence of HCV infection using rapid point-of-care testing and to assess liver fibrosis by non-inv
