The incidence of venereal diseases rose by 0.6 per cent during
1973. This increase is considered slight, compared with many other parts of the world. The incidence in the teenage group was approximately 5.4 per cent
of the total cases of venereal disease. The trends over the past ten years
are illustrated in Figure 8 to 10.

During recent years, there has been some advance in overcoming
the prejudice against employment of cured leprosy patients, and to this end
great attention was paid by the social hygiene service in 1973 to the
prevention of disabilities in tuberculoid cases.
Dermatology
83.
Dermatology clinics were held in various centres. Table 33
shows the incidence of skin diseases seen at the clinics. The total number of
new cases was about 10.5 per cent more than the previous year. It is
noteworthy that the incidence of skin cancers has remained low as in previous
years.
