[Pre-print, not peer reviewed] COVID-19 transmission patterns in the state of Georgia evolved over time, including a contraction of the serial interval between cases and a downward shift in the age of index cases. Data from 4,080 transmission pairs show that the serial interval decreased from 6.0 days in February-April to 4.4 days in June-July. The age range contributing most to the spread of SARS-CoV-2 shifted from ages 40-70 years in February-April to 20-50 years old in June-July. Two distinct waves separated by a shelter-in-place period were identified, suggesting that measures were not long enough to suppress COVID-19 transmission in areas with high transmission, such as densely populated areas and areas near interstate highways.
