To find the extent and spread of endemic tuberculosis in La Rioja and assess its tuberculosis control programme.
Prevalence study.
Both public and private EGB (general basic education) schools in Logroño.
All students registered for the first year of EGB.
A tuberculin test, consisting of two international units (IU) of PPD-23 with tween 80, was carried out. We obtained a prevalence of tubercular infection of 1.12 +/- 0.58%, with a 95% confidence interval and standard error calculated at 0.29%.
The rate of prevalence of tubercular infection in children doing the first year of EGB in La Rioja is high, as seen in the high rates of incidence and carriers. The findings support the appropriateness of continuing with this type of study, for two reasons. The first is the need to establish the annual risk of infection (ARI) in order to monitor how endemic tuberculosis evolves in our community and assess the tuberculosis control programme. The second reason is that, by checking infected children, it becomes possible to prevent or treat new cases of tuberculosis and find possible unknown sources and future reservoirs of infection.
了解拉里奥哈地区地方性结核病的范围和传播情况，并评估其结核病控制项目。
患病率研究。
洛格罗尼奥的公立和私立基础教育学校。
所有注册参加基础教育第一年的学生。
进行了结核菌素试验，使用含吐温80的两个国际单位（IU）的PPD - 23。我们得出结核感染患病率为1.12 +/- 0.58%，计算出95%置信区间和标准误差为0.29%。
拉里奥哈地区基础教育第一年儿童的结核感染率很高，发病率和携带者比例也很高。这些发现支持继续开展此类研究的合理性，原因有二。一是需要确定年度感染风险（ARI），以监测我们社区地方性结核病的发展情况并评估结核病控制项目。二是通过检查受感染儿童，有可能预防或治疗新的结核病病例，并找到可能未知的感染源和未来的感染储存宿主。
