Analysis of epidemiological situation of influenza in Poland in 2013 and 2013/14 epidemic season in reference to previous years and seasons.
Analysis was based on: 1) data collected within influenza routine surveillance system in Poland, including data published in annual bulletins “Infectious diseases and poisonings in Poland” as well as unpublished data gathered in the Department of Epidemiology of the NIPH-NIH; 2) data collected within influenza system - Sentinel, and beyond this system, concerning results of virological tests carried out in 2013/14 epidemic season in the Department of Influenza Research, National Influenza Center in the NIPHNIH and/or laboratories of provincial sanitary and epidemiological stations which are gathered in the National Influenza Center.
Compared to 2012, the number of influenza and influenza-like cases increased more than twofold in 2013 in Poland. A total of 3 164 405 cases were reported. Incidence was 8 218.7 per 100,000 population (33 733.2 in 0-4 age group). As many as 0.45% of patients were referred to hospitals. According to the data of the Central Statistical Office, 115 deaths due to influenza were notified. Based on the data of the sanitary inspection (incomplete data), the percentage of population vaccinated against influenza was 2.4% (7.7% of persons aged more than 64 years). A total of 2 780 945 cases were registered in 2013/14 epidemic season. Its peak was reported in March 2014. Incidence was 7 224.0 per 100,000 population (35 172.8 in 0-4 age group). Compared to 2012/13 epidemic season, it was lower by 8.0%. Incidence rates ranged from 29 339.6 in pomorskie voivodeship to 1 306.5 in lubuskie voivodeship. Nearly a half of all cases (48.7%) were registered in children and adolescents up to 15 years. As many as 0.34% of patients were referred to hospitals (0.87% of persons aged more than 64 years). From the data of the Central Statistical Office transpires that 8 deaths due to influenza were reported in epidemic season. Type A influenza subtype H3N2 predominated in all influenza cases. Human respiratory syncytial virus (RSV) was the dominant agent in other viral infections of respiratory tract. Antigenic analysis of influenza strains showed their affinity with vaccine strains of the vaccine recommended for this epidemic season.
In spite of slow improvements, influenza and influenza-like surveillance system in Poland is still not homogeneous and stable enough. It hinders the assessment of current epidemiological situation. For instance, there are difficulties in determining what is the effect of modifications in the surveillance on the increase in the number of influenza and influenza-like cases observed in Poland in recent years. A low percentage of population vaccinated against influenza (with a decreasing trend beginning from 2005) suggests a necessity of revising the methods of promotion and organization of these vaccines used so far. One of the public health priorities should be to increase the percentage of vaccinated population up to the average level in EU countries.
参照前几年和季节情况，分析2013年及2013/14流行季节波兰流感的流行病学状况。
分析基于：1）波兰流感常规监测系统收集的数据，包括年度公报《波兰的传染病和中毒》中公布的数据以及国家公共卫生研究所-国家卫生研究院流行病学部收集的未公布数据；2）流感哨点系统及该系统之外收集的数据，涉及2013/14流行季节在国家公共卫生研究所-国家卫生研究院流感研究部、国家流感中心和/或省级卫生防疫站实验室进行的病毒学检测结果，这些数据汇总于国家流感中心。
与2012年相比，2013年波兰流感及流感样病例数量增加了两倍多。共报告3164405例。发病率为每10万人8218.7例（0 - 4岁年龄组为33733.2例）。多达0.45%的患者被送往医院。根据中央统计局的数据，通报了115例因流感死亡病例。根据卫生检查数据（不完整数据），接种流感疫苗的人口比例为2.4%（64岁以上人群为
