Aug 10th, 2020 - The clinical onset serial interval is often used as a proxy for the transmission interval of an infectious disease. For SARS-CoV-2/COVID-19, data on clinical onset serial intervals is limited, since symptom onset dates are not routinely recorded and do not exist in asymptomatic carriers. We define the diagnostic serial interval as the time between the diagnosis dates of the infector and infecte...
