We have developed a novel approach to integrate test data and death toll to estimate probability of contracting COVID-19, as well as the time-dependent transmission rate and the number of active infectious individuals at the county level in the US. Furthermore, when we reduce the infectious period by 10% (or equivalently 4.5 days in total), while the transmission rate (β t in SIRDC model) is held the same, the PoC SARS-CoV-2 is reduced by 5 times for 26 counties in Washington and 146 counties in Texas, shown in Extended Data Figure 4 . ./cache/cord-171703-n22tr8f2.txt ./txt/cord-171703-n22tr8f2.txt
