The presence of 4 peaks in the mortality rate was found — in 2009, 2012, 2014 and 2016. On the territory of the Penza region, the infection has a pronounced winter-spring seasonality, there are generalized forms of meningococcal infection and localized forms of meningococcal infection.
Conclusions. Thus, meningococci of serogroups B and C prevail in the serogroup landscape of meningococci in the Penza region. The excess of the average Russian indicators of the incidence of meningococcal infection was revealed by 2 or more times throughout the entire study period. patients under the age of 14 from unorganized groups predominate among patients with meningococcal infection. the Gender structure is dominated by males from rural areas.
