摘要：First, I talk why old epidemic diseases reemerge from the point of competitive exclusion point of view. I show you a mathematical model which captures the main feature of epidemic transmissions with two viral strains. It is shown by analytical method that the model exhibits the competitive exclusion principle, where one viral strain with the larger basic reproduction number is dominant and the viral strain with the smaller reproduction number is excluded. After that, I talk about the dynamical analysis of age-structured pertussis model with covert infection. It is shown that although the vaccine coverage rate is relatively high, the model has a backward bifurcation for a larger covert infection rate. Finally, I present our studies for mathematical modeling for scarlet fever with direct and indirect infections. The threshold conditions for disease invasion are obtained in terms of the basic reproduction number.
