The follow up study of family contacts of tuberculosis patients have been continued for four years after the detection of index cases in order to know to what extent the family contacts examination was performed at the health centers in Osaka prefecture and how many cases requiring treatment were discovered among total household members. This report is the over all results of four years, follow up. The survey on the fourth year was re peated in the same way as in the past three years. Out of 815 patients newly registered at the 12 health centers of Osaka prefecture during the period from January to June, 1976, 357 were omitted from the registry by the end of October, 1978, and 1250 family members of the remaining 458 patients were subjected to study. Out of 1230, 430 (34.4%) were examined by the contacts examination (Table 1). The atten dance rate of contacts examination showed marked difference according to health centers (Table 2). One new case was found by the examination. The detection rate of contacts examination was 0.2%. Another two cases were found by symptomatic visit to clinic. Total number of new cases requiring treatment among family members during the fourth year after the discovery of index cases was 0.2% (Table 2). Among family members, 274 (21.9%) have not been examined at all during four years after the discovery of index cases and only 47 (3.8%) have been examined every year (Table2, 3, 4). During the past four years, altogether 48 cases were found (Table 5). The detection rate was higher in the first and second years, especially among contacts of bacillary cases and it markedly fell down in the third and fourth years (Table 6, 7, Fig. 1). It can be concluded that the contacts examination should be thoroughly carried out in the first two years after the discovery of index cases, especially for contacts of bacillary cases.
