[Pertussis in Poland in 2007].

In 2007 number of reported cases of pertussis in Poland was 1987 (5.2/100,000), 31% more then in the previous year (1520 in 2006). Higher incidence was among females (1109 cases, 5.6/100,000) than among males (878 cases, 4.8/100,000). In urban areas incidence was significantly higher (1448 cases 6.2/100,000) than in the rural ones (539 cases 3.7/100,000). 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.
