title: Infectious diseases in Poland in 2012.
abstract: OBJECTIVE
  The aim of the study is to assess the epidemiological situation for infectious and parasitic diseases in Poland in 2012.
  
  
  METHODS
  The main source of data for this study are statistical overviews contained in the annual bulletins "Infectious Diseases in Poland in 2012" and "Immunizations in Poland in 2012" (NIPH-NIH, Warsaw 2013) and data contained in the articles presented in this issue of Przegląd Epidemiologiczny. Information on deaths due to infectious and parasitic diseases registered in Poland in 2012 and earlier years is based on the data of the Department for Demographic Research of Central Statistical Office.
  
  
  RESULTS
  Upper respiratory tract infection classified as "influenza and influenza-like illness" were reported in 2012 in a total number of 1 460 037 cases. In comparison with 2011, it was an 26.2% increase of incidence, and as compared to the median of 2006-2010 of 286.1%. In 2012, with still the clear predominance of salmonellosis among intestinal bacterial infections, downward trend in the incidence of intestinal infections of this etiology persisted. In 2012 reported number of intestinal infections caused by Salmonella was, 8 267 (21.5/100 000), which represents incidence decrease of 4.5%. Foodborne infections of viral etiology were reported in 39462 cases (102.4/100 000). Most frequent were caused by rotaviruses - 23 692 (61.5/100 000). In 2012, there were 4 684 reported cases of pertussis (12.2/100 000), which means an increased incidence compared with the previous year by 180%. In 2012, there was an increase in the number of cases of mumps by 7.5% (from 2 585 to 2 779 cases), and of rubella by 46.0%, but compared to the median of the years 2006 to 2010 it was a decrease of 52.9%. In 2012, there was not any case of congenital rubella. Number of measles cases was 70 (0.18/100 000). In 2012, there was an increase in the number of cases of invasive disease caused by H. influenzae from 31 in 2011 to 36 in 2012. Number of infections caused by Streptococcus pneumoniae remained in 2012 as compared to 2011, on almost the same level: 436 in 2012 and 430 in 2011. However, there was a 36% increase in the number of sepsis cases caused by this organism. The incidence of tuberculosis in total (all forms of TB) in 2012 decreased compared to the previous year from 22.0 to 19.6 /100000, and pulmonary tuberculosis from 20.5 to 18.2. In 2012, were reported 1 093 cases of HIV infections (2.84/100 000), compared with the previous year, it was a fall in incidence of 2.4%. 21 cases of malaria occurred in people, who infection acquired abroad in malaria endemic areas. In 2012, there were no cases of diphtheria, poliomyelitis, rabies and viral haemorrhagic fevers outside of dengue, of which 5 cases of infections acquired in endemic areas were reported to National Sanitary Inspection. Total number of people who died in Poland in 2012 due to infectious and parasitic diseases, was 2 774. The share of deaths from these causes in the total number of deaths was 0.72%, and the mortality rate - 7.2/100 000. Out of all those deaths 41.1% were due to sepsis.
