202. Examinations of contacts is so arranged that only contacts under 8 years of age need attend the clinic for tuber- culin test. Older members of the family go straight to the hospital for X-ray and need attend the clinic only if the X-ray shows evidence of pulmonary tuberculosis.
203. The results of contact examination were as follows:
Tuberculin Test of contacts & years and under
X-ray findings of chidren
8 years and under, sub- sequent to positive tuberculin test
Active tuberculosis Inactive or healed
204. The high incidence of pulmonary tuberculosis in con- tacta will be seen from the above figures, Expressed as a per- centage the following results are obtained:
Contacts less than 8 years of age examined and found to have active pulmonary tuberculosis
Contacts over 8 years of age examined and}
found to have active pulmonary tuberculosis
9.2%
8.2%
205. These results amply justify the large amount of time and labour expended on contact examination.
206. At the same time much valuable educational work is being done by the tuberculosis workers in the home, the value of which cannot be set out statistically.

208. Many employers, for various reasons are learning to appreciate the value of X-ray surveys and more and more re- quests are reaching the department to have such examinations carried. Under present conditions such surveys are carried out free of charge provided the firm concerned is prepared to make adequate social and medical provision for positive cases found. In some cases surveys are carried out by one of the two fixed 36 mm. X-ray units, in others for convenience, the surveys are carried out by the mobile X-ray unit given by UNICEF to the Hong Kong Government.
