To identify spatiotemporal patterns of epidemic spread at the community level. <\/jats:p><jats:p> Methods. We extracted influenza cases reported between 2016 and 2019 and COVID-19 cases reported in March and April 2020 from a hospital network in Rhode Island. We performed a spatiotemporal hotspot analysis to simulate a real-time surveillance scenario. <\/jats:p><jats:p> Results. We analyzed 6527 laboratory-confirmed influenza cases and identified microepidemics in more than 1100 neighborhoods, and more than half of the neighborhoods that had hotspots in a season became hotspots in the next season. We used data from 731 COVID-19 cases, and we found that a neighborhood was 1.90 times more likely to become a COVID-19 hotspot if it had been an influenza hotspot in 2018 to 2019. <\/jats:p><jats:p> Conclusions. The use of readily available hospital data allows the real-time identification of spatiotemporal trends and hotspots of microepidemics. <\/jats:p><jats:p> Public Health Implications. As local governments move to reopen the economy and ease physical distancing, the use of historic influenza hotspots could guide early prevention interventions, while the real-time identification of hotspots would enable the implementation of interventions that focus on small-area containment and mitigation. <\/jats:p>","DOI":"10.2105\/ajph.2020.305911","type":"journal-article","created":{"date-parts":[[2020,10,15]],"date-time":"2020-10-15T20:00:27Z","timestamp":1602792027000},"page":"1817-1824","source":"Crossref","is-referenced-by-count":7,"title":["Real-Time Spatiotemporal Analysis of Microepidemics of Influenza and COVID-19 Based on Hospital Network Data: Colocalization of Neighborhood-Level Hotspots"],"prefix":"10.2105","volume":"110","author":[{"given":"Evangelia K.","family":"Mylona","sequence":"first","affiliation":[{"name":"At the time of the study, all authors were with the Infectious Diseases Division, Warren Alpert Medical School of Brown University, Providence, RI.
