Brief Summary: The 2013-2015 Ebola Virus outbreak in Western Africa was unprecedented in size and geographic scope. There were over 28,000 cases and 11,000 deaths. During and following the outbreak, it became evident that spectrum of disease being observed in the communities and the Ebola treatment units was much broader than previously thought. In this study, we aim to identify host genetic factors that underlie the observed variation in disease susceptibility, severity, clinical sequelae, viral persistence, and serological response. We will enroll EVD survivors, close contacts of survivors, EVD healthcare workers, and individuals who have received investigational Ebola vaccines (population controls), and collect a blood sample, HIV/syphilis infection status, demographics, and medical history from participants. Most subjects will complete study participation after a single study visit; subjects having HIV/syphilis testing done as part of this study will return for a second visit to receive their HIV/syphilis test results and post-test counseling. We will genotype participants and compare results between cohorts to address the study aims. This may provide insight into pathogenesis and host immunity and potentially suggest new methods of intervention.
