USE OF SEVERAL PA RAMETRIC CHARACTERISTICS FOR STUDY OF EPIDEMIC FEATURES OF MENINGOCOCCAL INFECTION AND BACTERIAL MENINGITIS

Continuous surveillance for main indicators of epidemic process of meningococcal infection and etiology of bacterial meningitis. Epidemiologic surveillance was electronically-based and was performed on the basis of specially developed standardized case reporting form. Main parameters of epidemiologic surveillance included 10 indexes. Information on 18,519 cases was obtained from 47 regions of Russian Federation. Organization of personalized registry of patients with meningococcal infection and bacterial meningitis allowed to reveal etiologic structure of the disease, territorial differences in serogroup landscape of clinical isolates of meningococci, shortcomings in laboratory diagnostics as well as features of meningitis caused by pneumococci and Haemophilus influenzae type b. Conclusion. Necessity of continuous epidemiologic surveillance for meningococcal infection and bacterial meningitis with mandatory use of modern methods of laboratory diagnostics as well as organization of official registration system for meningitis caused by pneumococci and Haemophilus influenzae type b providing decrease of morbidity and development of vaccination tactics was substantiated.
