| description | Aim. Analyze epidemiologic and clinical features of influenza epidemic seasons 2009 - 2010 and 2015 - 2016. Materials and methods. Forms of federal state statistic observation No. 1, 2, 5, and 6; information from the official web-site of the Research Institute of Influenza of the Ministry of Health of Russian Federation; materials of various conferences and congresses on problems of influenza; information-analytical certificates of the Ministry of Health of Russian Federation. Results. Epidemic morbidity increases in the season 2009 - 2010 and 2015 - 2016 started at various time and had different duration. Children younger than 14 years of age predominated in the structure of patients in the 2009 - 2010 epidemic season, the main mass of patients were presented by individuals aged 45 - 59 years in the 2015 - 2016 season. The number of lethal outcomes with laboratory confirmed influenza diagnosis in 2009 - 2010 was 687 cases, and in 2015 - 2016 - 663 cases. Almost all the deceased from influenza were not vaccinated against this infection. Cardiovascular system diseases were noted in 484 individuals of the total number of deceased. Most of the deceased were late to seek medical aid. Conclusion. Influenza epidemic season 2015 - 2016 differs from 2009 - 2010 season by dynamics of morbidity development and a lower amount of severe forms of the disease and lethal outcomes. This may be due to an increase of population immunity against pandemic strain A(HlNl)pdm09 via pro-epidemizing in the recent years as well as an increase of influenza vaccination coverage. |
