This issue of the Journal focuses on Communicable Diseases impacting the health and wellness of Delawareans.

The focus on infectious diseases in public health ebbs and flows. Students of the field are taught that developed countries have undergone an epidemiological transition whereby morbidity and mortality from noninfectious diseases has eclipsed that of infectious causes. Nevertheless, infectious etiologies of disease remain a substantial threat to the public’s health. The last decade has seen a re-emergence of vaccine-preventable diseases, including pertussis and measles; an increase in sexually transmitted infections (STIs) most notably syphilis among gay, bisexual, and other men who have sex with men ; a worsening Hepatitis C infection (HCV) crisis in the setting of the opioid epidemic; and the ongoing struggle to control the HIV epidemic well into its fourth decade. To that end, we have solicited a wide range of experts in infectious disease epidemiology, public health practice, and clinical medicine to contribute insightful, and at times, provocative discussions of important infectious diseases within Delaware. Globally, nationally, and locally, healthcare systems face many challenges related to infectious diseases, from creating the infrastructure and microenvironments to support responsible antibiotic prescribing practices to immunization advocacy (and rapid response to complications stemming from a lack of adequate vaccination coverage) to ongoing efforts to test and treat for STIs. This issue of the Delaware Journal of Public Health tackles these broad issues.
