With tuberculosis (TB) rates of over 160/100,000 in 1997, Ciutat Vella District, Barcelona, is the main community focus of TB in the city. For the purpose of TB screening, 415 children >2 years old from that district received a tuberculin skin test (TST); 27 (6.6%) (95%CI 4.5-9.3) were found to be infected but disease-free. The frequency of a positive TST increased significantly with age, from 0% in the 2-4 year age group to 14.6% in 10-14 year olds. Three culture-positive source adults, two of them sputum smear-positive, who were not previously known were traced from six TST-positive children. Previous BCG vaccination was not associated with a positive TST. These data support the use of universal TST screening in children living in Ciutat Vella District, Barcelona, as a means of identifying and treating TB cases.
1997年，巴塞罗那旧城区的结核病发病率超过160/10万，是该市结核病的主要社区聚集区。为了进行结核病筛查，该地区415名2岁以上儿童接受了结核菌素皮肤试验（TST）；发现27名（6.6%）（95%可信区间4.5 - 9.3）感染但无疾病。TST阳性的频率随年龄显著增加，从2 - 4岁年龄组的0%增至10 - 14岁儿童的14.6%。从6名TST阳性儿童中追踪到3名培养阳性的传染源成人，其中2名痰涂片阳性，此前并不知晓。既往卡介苗接种与TST阳性无关。这些数据支持在巴塞罗那旧城区儿童中进行普遍TST筛查，作为识别和治疗结核病病例的一种手段。
