Abstract
The possibility of representation in a dynamic model of the three types of SARS-CoV-2 infection: asymptomatic, pre-symptomatic and symptomatic is studied. Furthermore, a compartmental model was proposed, with a branching of asymptomatic cases into pre-symptomatic and actually asymptomatic cases. Verification of the proposed model using data from the first wave of COVID-19 in St. Petersburg and the proportion of actually asymptomatic cases among all asymptomatic cases demonstrated adequate model behavior. The contribution of pre-symptomatic cases to the total number of symptomatic cases was studied. The need to account for the high proportion of asymptomatic carriers in strict quarantine was identified.
