In this report, invasion of pathogens was studied assuming nearest-neighbor interaction. Ultimate state of population was obtained by an approximation called modified decoupling approximation (MDA), the validity of which was checked by computer simulation. Main results are as follows. (1) In 2-dimensional model there is a parametric region in which host population is extinguished by invasion of pathogens. (2) In 1-dimensional model ultimate invasion of pathogens is impossible however strong is the infectious rate.
