Abstrakt: This article examines a general infectious disease model and proposes a new epidemic threshold and an epidemic scale forecasting formula. Then a system dynamics model of an eruptive spread of type-A hepatitis in Shanghai in 1988 is presented. Various problems are resolved: simulating the incubation period of type-A hepatitis; fitting the simulation results to real data; analyzing the reason that the predicted second peak of the eruptive spread did not occur. Short-and long-term prospects for recurrence are considered, especially the mechanisms of periodic epidemics and eruptive spreads of type-A hepatitis. The results of this study have import for the prevention and control of type-A hepatitis and other infectious diseases. [ABSTRACT FROM AUTHOR]
