Document: We modified a SEIR model to account for a dynamic Susceptible Fig.2 . Here, we assume that susceptible population E represents susceptible population of a certain region; and ï¢ represents effectiveness of intervention (strict isolation) in contain phase. If effectiveness of intervention in contain phase is not sufficiently strong, susceptible individuals may contract the disease with a given rate when in contact with a portion of exposed population (asymptomatic but infectious) E. After an incubation period, the exposed individuals become the infectious population I (symptomatic) at a ratio α1. Notably, infectious population starts from mild cases M to critical cases C at a ratio α2. Finally, a portion d of critical cases lead to deaths; the rest of infectious population will be recovered.
