INTEGRATIVE APPROACH TO THE STUDY OF PERENNIAL AND ANNUAL DYNAMICS OF THE INCIDENCE OF HEPATITIS A AND SHIGELLOSIS

Abstract

In epidemiology, traditionally it is accepted to separately consider the epidemic process of specific infections. However, in the human population at the same time many pathogens circulate and cause disease in people. The question remains to be open: does every epidemic process in the each case occurs as alone or being interconnected with the epidemic process of other infectious diseases? The implementation of the integration method in the study of the spread of causal pathogens with similar transmission mechanism contributes to a more objective conclusion on this issue. The purpose of the research is a comparative epidemiological estimation of the long-term and annual dynamics of the morbidity rate of hepatitis A (HA), shigellosis Sonnei and Flexneri. Materials and methods.There were used data of the official accounting of the incidence of hepatitis A and shigellosis Sonnei and Flexneri in the total population of the Primorsky territory for 1986-2014. The treatment of obtained results was carried out with the use of techniques of epidemiological diagnosis, conventional statistical methods and computer applications Microsoft Excel 2010. Results. The obtained results showed the long-term prevalence rate of hepatitis to be in the opposite phase as the prevalence rate of shigellosis Flexneri, and Sonnei. The periods and maximums in the annual dynamics of the incidence of specified infections also did not coincide. Conclusion. Epidemiс process of these infections develops autonomously. However, its autonomy is relative and possibly is implemented through evolutionary established of integrative and competitive interrelationships between the agents.
