Tb infection prevalence and incidence are considered as the most relevant epidemiological indices which characterizes the endemic disease in a population. The study tried to establish the level of Tb infection prevalence in the age groups "6-7" and "14-15", based on the information included in the card-index for BCG pre- vaccination in the above groups, in 11 districts of Romania and the city of Bucharest. To calculate the Tb prevalence results from the BCG tests in 24,175 pupils aged 6 and 14, the persons with reactions of 10-19 mm Palmer type I-II, and reactions > or = 20 mm regardless the Palmer type were considered as infected. In 1990, infection prevalence was of 2.13% and 6.73% in pupils aged 6 and 14, respectively. The study was not intended to establish the average level of Tb infection prevalence for the whole country since it would have required adequate samples of population and working teams of the same technical level as regards skin testing and its interpretation. The obtained data allowed the calculation of the average annual rate of infection for "age-group 0-6" within the study group (0.36%). It is estimated that infection prevalence evolution can be followed up at district level, by processing the data of the card-index for pre-vaccinal tests in the pupils of the I-st and VIII-th forms.
结核病感染患病率和发病率被视为表征人群中地方病的最相关流行病学指标。该研究试图根据罗马尼亚11个地区和布加勒斯特市上述年龄组（“6 - 7岁”和“14 - 15岁”）卡介苗接种前卡片索引中的信息，确定结核病感染患病率水平。为计算24175名6岁和14岁学生卡介苗试验的结核病患病率结果，帕尔默I - II型反应为10 - 19毫米以及无论帕尔默类型反应大于或等于20毫米的人均被视为感染。1990年，6岁和14岁学生的感染患病率分别为2.13%和6.73%。该研究并非旨在确定全国结核病感染患病率的平均水平，因为这需要足够的人群样本以及在皮肤试验及其解读方面具有相同技术水平的工作团队。所获数据使得能够计算研究组内“0 - 6岁年龄组”的年平均感染率（0.36%）。据估计，通过处理一年级和八年级学生接种前试验卡片索引的数据，可以在地区层面追踪感染患病率的变化情况。
