| Abstract: | A kind of infectious mode with short or long incubation period is discussed and thus an equation system with a small parameter is induced.By using the boundary layer method of the singular perturbation and asymptotic analysis, a uniformly useful asymptotic solution is obtained. |

| Keywords: | infectious disease threshold asymptotic solution small parameter incubation period |
