M.V. Vorobyev Summary. Viral hepatitis primary morbidity during the three years of 2009-2011 has declined by 3.6% in the Russian Federation. The overwhelming majority of viral hepatitis primary cases pertained to people aged 18 years and older, and this proportion increased in Russia from 93.6% in 2009 up to 95.9% in 2011. In primary cases of 15-17 years of age, the male proportion was 58.4% in 2009 and 59.2% in 2011. In puerile population, overall incidence of viral hepatitis reduced by 18.8%, while primary morbidity - by 34.5%. Analysis of registry for this three-year period in every of Federal District has shown that most unfavorable situation with viral hepatitis overall morbidity lingered on in Far Eastern, Siberian, and North-Eastern Federal Districts, and with viral hepatitis primary incidence - in Far Eastern, Siberian, Urals, Pryvolzhsky (Near-Volga), and North-Eastern Federal Districts. Central Federal District accounted for 18.7% in 2009 and 19.8% in 2010 of primary incidence cases in Russia. Relative primary incidence slightly dropped down in these three-year period in Central Federal District: population-based ratio fell down from 55.1 to 54.3 cases upon 100,000 people of general population. As for Ivanovo region among Russia’s administrative divisions, it was ranked for viral hepatitis prevalence as 16th in 2009, 14th in 2010, and 11th in 2011, while most highly prevalent regions were those of Voronezh, Belgorod, Orel, and Tula. Region of Ivanovo accounted for 1.4% in 2009, 1.2% in 2010, and 1.4% in 2011 of registered viral hepatitis primary cases in Russia. Primary cases of 18 years of age and older accounted for 85.5% of viral hepatitis primary cases in 2009 and 88.0% in 2011 in the region of Ivanovo. A certain reduction in primary viral hepatitis incidence in this region was mostly due to diminishing number of cases of 0-14 years of age, in whom primary incidence fell down by 18.8% in this three-year period. Male adolescence dominance in overall and primary viral hepatitis incidence in puerile+adolescent (summed-up) population tended to grow through this period. The data processed in this study have evidenced certain improvements in the region of Ivanovo in the prevention of viral hepatitis spread in puerile population, and also among young parents.
