Title: [Tuberculin tests and the incidence of tuberculosis in students. Experiences from the Basle school health service]. Author: Ackermann-Liebrich U. Journal: Schweiz Med Wochenschr; 1984 Oct 27; 114(43):1495-9. PubMed ID: 6515349. Abstract: 15-year-old reactors to intradermic tuberculin tests were analized over the period from 1976 to 1983 to assess the prevalence of tuberculosis in this age group. The proportion of children with BCG vaccination increased in the observation period from 34% to 49%. The rate of spontaneous tuberculin convertors has therefore to be calculated as a proportion of the non-vaccinated children only. During the years 1976-1983, this rate was between a minimum of 6.3% and maximum 14.5%. Since the children had not been tested for four years previously, an incidence between 1.5 an 3% can be calculated for this age group.[Abstract] [Full Text] [Related] [New Search]
