The purpose of this study is to estimate the extent to which health care workers at MUSC who may have higher than average risk for exposure to the novel coronavirus SARS-CoV-2, which causes an illness referred to as COVID-19, may have developed immunity to infection. Two groups of people will be asked to participate in this study. The first group is comprised of health care workers with a potentially higher risk of exposure who may have provided direct care or services for persons with SARS-CoV-2 infection as part of their work duties. The second group is comprised of employees whose job duties do not involve direct contact with patients. The purpose of the research is to determine if a certain marker in blood, IgG to SARS-CoV-2, can tell if participants may have been exposed to and now recovered from SARS-CoV-2 infection and how seroprevalence changes over time during the current outbreak in this population of study subjects.
Treatment of chronic hepatitis C virus (HCV) infection is now possible with all oral medications. While most patients achieve a sustained virologic response (SVR) after treatment, synonymous with cure, some patients relapse after treatment for reasons that are unclear. The goal of this research is to understand how a person's immune system changes during treatment of HCV infection with all oral therapy, and how these changes might impact the chances of relapse after treatment. To address these questions, blood and clinical information will be collected from study participants over the course of receiving standard of care treatment for HCV infection. This blood and clinical information will be used to conduct laboratory research focused on the immune system.
