In spite of the generally accepted high infection and morbidity rates of tuberculosis in Korea, i.e., the total infection being estimated at 70 per cent of the whole population and the total tuberculosis patients grossed at 800, 000 to 1, 000, 000, the current socioeconomic situation does not seem to permit a successful management of this disease at homes of the ailing individuals.
For the purpose of underlining, if suitable, the reports of numerous authors on the high infection rates among the families of tuberculous patients and of verifying the extent of infection, which does not appear to have declined in rate in so much as the decrease of tuberculous morbidity during the last couple of decades resulting from the adva cement of chemotherapy, the author has conducted a series of investigation for a two year period; from April 1961 to March 1963, awards 874 contacts of 488 tuberculous patients for rates of infection and another 1, 540 contacts for morbidity.
The Results can be summarized as follows:
1. Therate of infection with intimate contacts of tuberculous patients turned out to be noticeably high, namely 43. 7% for the -age group of 0?4, 69.4% for 5?9 group and 82.5% for 10?14 group. No sexual difference of any significance was observable.
2. The infection rate of the contacts with index cases was definitely higher among the male than female.
3. Bacterirlogical observation has revealed that the infection rate was higher among the contacts with smear positive and culture positive cases than those with the negative cases.
4. The infection rate was considerably higher when the parents were the index cases compared with the cases where the relatives were the index cases.
5. The infection rate among those who had contacts with far advanced cases was highest and the same was owest among -those who had had ´contacts with minimal tuberculosis cases.
6. The contacts of the far advanced cases showed the highest rate of positive tuberculin reaction.
7. The infection was more frequent with those who were using the same room as-the patients than with those who were using separate rooms.
8. The rate of infection was higher with those who were using single rooms than with those using double rooms.
9. Observation of the tuberculin negative patients revealed that the highest proportion of cases turned positive during the first six month´s while the rate declined with lapse of time thereafter.
10. The tuberculosis morbidity rate of the contacts were definitely higher (7. 1%) than the general population. The same was higher among the male than female and was obviously high among those over 60 years of age.
11. The morbidity rate was higher among these who had had contacts with the female tuberculous patients.
12. Those who had had contacts with the far advanced index cases had a higher morbidity rate.
13. Those who had had -contacts with smear positive index cases manifested a higher rate of tuberculous morbidity.
14. Morbidity rate was high among the room sharers.
15. Tuberculosis morbidity rate was lowest among the contacts with users of INH alone and was highest among contacts of patients who were resort to herb medicines.
16. The tuberculosis attack rates were definitely lower throughout the period of observation than those at the time of initial examination of the cases.
