title: [Pertussis in Poland in 2002].
abstract: Reemergence of pertussis in a form of epidemic was observed in Poland in 1997/1998. It is rather sustained trend of increased incidence and shift in the age of infected. It may be due to the level of immunity decreasing with age, since according to the vaccination calendar in Poland, last pertussis vaccination is given before the age of two. 1788 cases were reported in 2002, a slight drop from the previous year (2411 in 2001) More cases occurred among females (1043 cases, 5.3/100,000) than among males (745 cases, 4.0/100,000) and in urban areas (5.7/100,000) than in the rural ones (3.0/100,000). 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. It is concluded that increase of pertussis incidence in Poland, brings urgent need of additional vaccination in the age of 6 to secure protection for the older age groups. Additional dose of pertussis vaccine was included in vaccination calendar for 2003.
