title: Pertussis in Poland in 2011.
abstract: BACKGROUND
  Results of the nationwide Pertussis Epidemiology Study implemented by Department of Epidemiology NIPH-NIH in 2009-2011 showed a high proportion of cases of whooping cough in adults whose only symptom of Bordetella pertussis infection was long lasting cough. It should be noted that the infected adults pose a risk of transmission of infection to susceptible contacts such as infants.
  
  
  OBJECTIVE
  To assess the epidemiological situation of pertussis in Poland in 2011, including vaccine coverage of children.
  
  
  METHODS
  Assessment of the epidemiology ofpertussis in Poland was based on analysis of individual reports of suspected cases of pertussis sent to the NIPH-NIH by the regional sanitary-epidemiological stations, data from the bulletin "Infectious diseases and poisonings in Poland in 2011" and bulletin "Immunizations in Poland in 2011 "(MP Czarkowski et al, Warsaw 2012, NIPH-NIH, GIS).
  
  
  RESULTS
  In 2011, number of registered cases of whooping cough was 1 669. The incidence was 4.3 per 100,000 children up to 15. It was higher than in the previous year (3.3/100,000) by 25.5%. The highest incidence occurred in children aged 3 years (20.8/100 000), and in people in the age group 10-14 years (20.3/100,000). Number of hospitalized persons was 648, (38.8%)of reported cases. In 2011, there were no deaths from whooping cough.
  
  
  CONCLUSIONS
  Higher the incidence of pertussis observed in 2011, compared with the previous year, may indicate improved sensitivity of the surveillance system.
