Almost 1% of all males over the age of 45 attending the Unit were found to be suffering from pulmonary tuberculosis. A letter from the Medical Officer of Health, advising adults to avail themselves of the services of the Mass Radiography Unit, was sent out with all rate demands des- patched from the City Treasurer’s Office. This was done with the help of the Finance Department and the Mass Radiography Unit’s staff and at the Unit’s expense. A third group of cases of pulmonary tuberculosis consisted of those examined at the Chest Clinic because others living in the same house had recently been found to be suffering from tuberculous disease or had been recently infected by tubercle bacilli. Twenty such “ contacts ” were found to be suffering from pulmonary tuberculosis. Ascertainment of Recently Infected Children A scheme involving the offer of annual tuberculin tests to all school and pre-school children was introduced in Cardiff in 1958. This scheme operated smoothly during 1959 and, as a result, it was possible to detect the majority of Cardiff children infected by tubercle bacilli during the year. This enabled steps to be taken to examine these children in order to determine whether or not active disease had resulted from the infection and to search for sources of infection among these childrens’ contacts. Table III gives an analysis of those children who had converted from a negative to positive tuberculin state in a period of twelve months.
