Improved SEIR model based on asymptomatic infection of COVID-19

ABSTRACT

With the rapid spread of COVID-19 worldwide, studying its transmission mechanism and exploring scientific control policies become important global issues. In this paper, SEIR epidemic model was improved by taking the asymptomatic infection into account and was used to simulate the spread of the epidemic in Hubei Province. Using the model to simulate and analyze the spread of the epidemic is helpful to provide references for the formulation of epidemic control policies at different stages. © 2021 IEEE.
