On the basis of general biological laws, connected with intrapopulational variety, the proposition proving that the optimum action time on the epidemic process is the minimum prevalence rate both in long-term and in year dynamics is substantiated. It is shown that both the parasite (shigellosis pathogenes) and host (patients with disenteria) have the least heterogeneity in the period of minimum disease intensity showing the instable state of parasitical system of the epidemic process. The proposition suggested is substantiated in the epidemiologic experiment on the model of disenteria. The epidemiologic experiment was carried out in five cities of East Siberia. The preventive measures made it possible to decrease shigellosis incidence.
