Abstract
Understanding the burden of antibiotic resistance globally is hindered by incomplete surveillance, particularly across low-resource settings. The Antibiotic Resistance in Communities and Hospitals (ARCH) consortium encompasses sites across 6 resource-limited settings and is intended to address these gaps. Supported by the Centers for Disease Control and Prevention, the ARCH studies seek to characterize the burden of antibiotic resistance by examining colonization prevalence at the community and hospital level and to evaluate for risk factors that are associated with colonization. In this supplement, 7 articles present results from these initial studies. Though future studies identifying and evaluating prevention strategies will be critical to mitigate spreading resistance and its impact on populations, the findings from these studies address important questions surrounding the epidemiology of antibiotic resistance.
