Major infectious disease outbreaks are a constant threat to human health. Clinical research responses to outbreaks generate evidence to improve outcomes and outbreak control. Experiences from previous epidemics have identified multiple challenges to undertaking timely clinical research responses. This scoping review is a systematic appraisal of political, economic, administrative, regulatory, logistical, ethical and social (PEARLES) challenges to clinical research responses to emergency epidemics and solutions identified to address these.

This pioneering study provides a precise follow-up of incident cases and seroprevalence in blood donors, and it also provides important insights into the management of blood donations during ZIKV outbreaks and into the natural history of ZIKV infection in adults. It suggests that the study of blood donors during outbreaks of emerging pathogens has become a key element of epidemiological surveillance.
