Introduction:
Tuberculosis is still a public health problem despite the steadily declining incidence rate in the wider Polish population. Effective prevention requires a good diagnosis of the problem on a regional scale, particularly among the younger population. Therefore, analysis of the incidence in the Silesian population with analysis of temporary differences in this trend among children and adolescents to 19 years of age was made.

Material and Methods:
The incidence rate and standardized incidence were calculated on data based from Central Statistical Office reports and data from Provincial Sanitary Epidemiological Station in Katowice. Data were analyzed with consideration of counties as a place of residence.

Results:
The standardized incidence rate of tuberculosis (n/100,000) in Silesian population between 2002–2013 amounted to: 25.5; 21.8; 22.1; 21.1; 17.3; 18.5; 17.1; 18.8; 19.8; 22.0; 19.9; 19.5. Percentage incidence in children and adolescents aged 0–19 years in subsequent years: 1.4%; 1.5%; 0.9%; 2.4%; 1.7%; 1.8%; 1.4%; 2.7%; 2.0%; 3.0%; 2.3%; 3.7%. The highest temporary differences of trend in children and adolescents are reported in Lubliniec county (0–35.2/100,000).

Conclusions:
Varied incidence of tuberculosis noted in the years 2002–2013 in Silesian area is followed by low percentage of tuberculosis cases in children and adolescents aged 0–19 years.The epidemiological situation of tuberculosis in most counties is stable. However, the increasing incidence in the youngest segment of the Silesian population in the last three years should be noted.
