Abstract

<p>Generalized meningococcal infection belongs to the group of diseases with a high risk of initiation of life-threatening conditions and death outcomes. There was carried out a retrospective analysis of clinical and epidemiological features of generalized meningococcal infections in children and adolescents of Saint Petersburg in 1995–2014 on the basis of the analysis of 884 medical records of the patients hospitalized at Scientific Research Institute of Children’s Infections. With general prevalence of the children of the first years of life among the patients, there has been revealed the tendency to reduction in the portion of children of the first year of life from 41,4% in 1995 to 22,2% by 2014, and the increase in the number of patients of 1–3 years old from 19,3–30,5% in 1995–1996 to 46,4–46,4% in 2013–2014. Among the number of etiologically identified cases (59,4%) the majority of them has been caused by serogroup B meningococcus (58,5%), in 24,2% – by serogroup C meningococcus, in 11,2% – by serogroup A meningococcus, and in 6,1% – by rare (W135/Y) and unspecified strains N.meningitidis. Within the recent years there has been identified the tendency of rate growth concerning the diseases caused by serogroup C meningococci, remarkable for a severe course and high rate of death cases. Total death indicator for the investigated period has averaged 4,2%, with the variability from 0 to 12,5% for different years.</p
