Abstract
Infectious disease reemergence is an important yet ambiguous concept that lacks a quantitative definition. Currently, reemergence is identified without specific criteria describing what constitutes a reemergent event. This practice affects reproducible assessments of high-consequence public health events and disease response prioritization. This in turn can lead to misallocation of resources. More important, early recognition of reemergence facilitates effective mitigation. We used a supervised machine learning approach to detect potential disease reemergence. We demonstrate the feasibility of applying a machine learning classifier to identify reemergence events in a systematic way for 4 different infectious diseases. The algorithm is applicable to temporal trends of disease incidence and includes disease-specific features to identify potential reemergence. Through this study, we offer a structured means of identifying potential reemergence using a data-driven approach.

Dr. Ramesh Krishnamurthy, along with other team members of the World Health Organization’s Department of Information, Evidence, and Research in the Health Systems and Innovation Cluster, provided subject matter expertise on disease reemergence as a global phenomenon, as well as detailed insight in the formative stages of the study. Dr. Bryan Lewis and James Schlitt, Biocomplexity Institute, University of Virginia, were important contributors to understanding the spatial components of disease reemergence. Dr. Reid Priedhorsky and Dr. Carrie Manore provided critical feedback on initial drafts of this article.
