TUBERCULINIZATION IN MICHIGAN
September 1963
1950, 26,315 tuberculin tests and 17,547 x-ray films were done. By 1961, the figures were 60,501 and 37,672, respectively. All food handlers have been required to have yearly chest x-ray films or tuberculin tests since 1952. These may be done by either unit or by private physicians. All admissions to the County Jail have had chest x-ray films since 1958. The chest x-ray film libraries and tuberculin records accumulated by each of these units have proved invaluable in differential diagnosis and clinical evaluation of newly discovered cardiopulmonary disease. Compulsory isolation in the hospital or by home quarantine of known bacteriologically positive patients has been enforced since 1954. We believe this program has contributed to a significant reduction of tuberculinization of the general population. SUMMARY
The percentage of tuberculin reactors in each ten year age group of the general population of Kent County, Michigan was determined from tests given in 1960 and 1961. These percentages are compared to a similar study of tests given the same population in 1950 and 1951. The comparison indicates a red uction of 0.5 per cent reactors in the first decade of life 3.2 per cent in the second, 16 per cent to 18 per cent in the third, fourth, fifth and sixth. The average decrease of reactors in each ten year age group was 13 per cent.

Por las pruebas realizadas en 1960 y 1961 el porcentaje de reactores a la tuberculina en cada grupo de hace 10 afios de la poblaci6n del condado de Kent se lIeg6 a determinar. Estos porcentajes se compararon con grupos similares de 1950-1951. La comparaci6n indica una reducci6n de 0.5 reactores para la primera decada de la vida, 3.2 por ciento para Ia segunda, de 16 a 18 por ciento para la tercera, cuarta y quinta decadas, EI termino medio de decrecimiento de los reactores en cada grupo de cada 10 afios es de 13.6 por ciento, ZUSAMMENFASSUNO
Es wurde der Prozentsatz von Tuberkulin-Reaktoren in jeder Zehn-Jahres-Gruppe der GesamtbevOlkerung des Kreises Kent in Michigan bestimmt an Hand von im Jahr 1960 und 1961 angestellten Testen. Diese Prozentsitze werden verglichen mit einer iihnlichen Untenuchung aufgrund von Testen der gleichen Bevdlkerung inden Jahren 1950 und 1951. Dieser Vergleich ergibt eine Reduzierung von 0,5% Reaktoren in der Lebensdekade, 3,3% in der zweiten, 16xbis 18% in der dritten, vierten, fiinften und sechsten . Die durchschnittliche Abnahme von Reaktoren in jeder Zehnjahre-Altersgruppe lag bei 13,6%. REFERENCE IRELAND, H. D. : "Tuberculin Reactors in the General Population," Dis. cu«. 25:221, 1954.
