Hepatitis C infection is a global phenomenon that affects millions worldwide, with an estimated 30,500 new cases in the United States alone each year. Expanding treatment, however, could go a long way toward preventing transmission of the virus among high-risk individuals who inject drugs, according to new Yale-led research.
For the study, infectious disease experts Alexei Zelenev and Dr. Frederick Altice, and their research colleagues used data from 1,574 people who inject drugs to model different treatment strategies. They employed a network-based study design to reflect how hepatitis C commonly spreads among individuals in a social network of people who inject drugs. They then simulated transmission of the virus through the network, using varying levels of hepatitis C prevalence and treatment coverage, and analyzed different strategies targeting individuals based on their network position.
