The Pirquet reaction as the most sensitive method of mass examination plays the main role in the study of tbc infectivity. It is the extreme sensitivity of this reaction that prevents it from serving as a means of judging the spread of tbc: while in children under 3-4 years of age both negative and positive Pirquet reactions have diagnostic value, with the latter usually indicating the presence of tbc disease in a child at a given time, in older children a positive reaction only indicates that the body was once infected with tbc and is fighting the infection, but does not prove that it is now sick.
