Abstract

Introduction: In the recent years there has been an increase in the incidence of infectious diseases that may be caused by the lack of guardians' consent to carry out immunization among children. In Poland in 2012 there was an increase in the incidence of pertussis 180% higher than in 2011. Occurring symptoms of pertussis can occur with varying intensity depending on the patient's age, his general health and the number of taken doses of vaccination against pertussis. The aim of the study was the analysis of reported in the years 2004 - 2013 confirmed cases of pertussis in the district of Bielsko and the city Bielsko- Biala, regarding to the prevalence of disease, the age of patients and the current course of compulsory vaccination against pertussis.

Methods: The analysis comprised 110 people with confirmed infection with Bordetella pertussis. The analysis included data from the years 2004-2013.

Results: On the basis of the analysis of the results the highest number of the patients with pertussis was reported in 2012. Women suffered more often than men. The median of the age of patients was 14 years. Pertussis was diagnosed in 7 infants, of which 5 have not yet received vaccination against pertussis. After 17 years of age incidence of pertussis occurred sporadically and involved 1-2 cases in each age group. 15,5% of patients had mandatory vaccination, and 52,7% of patients who suffered from pertussis received all doses of the primary vaccination, compulsory to the second year of life.
