“A new machine learning-based online tool developed by researchers at Harvard Medical School, Massachusetts General Hospital, Georgia Tech and Boston Medical Center allows for early detection of COVID-19 outbreaks in different U.S. counties. The COVID-19 Outbreak Detection Tool, updated two to three times per week, predicts how fast an outbreak is spreading within a given county by estimating the doubling time of COVID-19 cases…The tool offers an interactive map and a “data explorer” that allows users to select a specific county to see that county’s population, total new cases and average daily cases of COVID-19 in the past week and the COVID-19 doubling rate, or how many days it takes for the number of cases to double in a given county…”
