[Pertussis in 2006].

In 2006 number of reported cases of pertussis in Poland was 1520, 21% less then in the previous year (1925 in 2005). Slightly higher incidence was among females (846 cases, 4,3/100 000) than among males (674 cases, 3,7/100 000). In urban areas incidence was significantly higher 1185 cases (5,1/100 000) than in the rural ones 335 (2,3/100 000). Incidence in urban areas was higher in all age groups. In general number of cases reported in Poland remains relatively low. Problem is uneven distribution in different voivodeships (districts) which bring strong possibility of very low sensitivity of surveillance in some regions.
