[Pertussis in Poland in 2003].
Since reemergence of pertussis in Poland since 1997/1998 shift of incidence toward older groups of age was observed. Possible explanations include decreased effectiveness of used whole cell pertussis vaccine and lack of booster vaccinations in the age older than two. At least this last possibility was eliminated by introduction of additional dose of DTaP at the age of 6. Though effects of this change may be observed within several oncoming years. 2034 cases were reported in 2003, a slight increase from the previous year (1788 in 2002) More cases occurred among females (1159 cases, 5.9/100,000) than among males (875 cases, 4.7/100,000) and in urban areas (6.8/100,000) than in the rural ones (2.9/100,000). Big differences in numbers of cases reported between different districts and between urban and rural areas bring strong possibility of insufficient sensitivity of the surveillance in many regions of Poland.
