A survey was carried out in certain parts of India to determine the prevalence of nonspecific tuberculin sensitivity. In the temperate zone, villages situated 1 200 m or more above mean sea level showed a markedly lower prevalence than villages in the plains did. In the tropical zone, the prevalence of nonspecific sensitivity was high. The prevalence of infection due to Mycobacterium tuberculosis was much lower than that of nonspecific sensitivity and the rates did not vary greatly in the areas surveyed.
在印度的某些地区进行了一项调查,以确定非特异性结核菌素敏感性的流行情况。在温带地区,海拔高于平均海平面1200米或更高的村庄的流行率明显低于平原地区的村庄。在热带地区,非特异性敏感性的流行率很高。结核分枝杆菌感染的流行率远低于非特异性敏感性,且在所调查地区发病率变化不大。
