INCIDENCE LATE PER 100 SOU PUPILATION OVER AGE 15
43. Case finding continued at a high level, particularly in ante-natal cases where an initial positive serology rate of 2.2% was observed, which, after further investigations, showed that 1,3% of the ante-natal cases were suffering from syphilis. Contact tracing, particularly of infectious syphilis, was continued.
Leprosy
44. New cases of leprosy treated numbered 217, representing a rate of 5.7 per 100,000 of population which is the lowest recorded since 1959. Tuberculoid manifestations predominated, the ratio of these to lepromatous cases being 1.7:10. Of the infectious cases. 95 were admitted to Hay Ling Chau Leprosarium (Island of Happy Healing) maintained by the Leprosy Mission-Hong Kong Auxiliary, with whom the Social Hygiene Service maintains close liaison.
45. During recent years there has been some advance in overcoming the prejudice against employment of cured lepers and, to this end, great attention is paid by the Service towards the prevention of dis- abilities in tuberculoid cases. In June 1965 the Leprosy Ordinance was repealed and accompanying legislative measures added leprosy to the statutory list of notifiable infectious disease. It is no longer regarded as a disease calling for special discriminatory measures against affected persons.
Dermatology
46. A significantly high incidence of systemic lupus erythematosus continues to be noticed and investigations into possible reasons are proceeding. Apart from pyoderma in infants during summer months, high incidences also continue to be recorded of conditions arising from urtication and lichenification and also of functional disorders such as alopecia areata, vitaligo and neurodermatitis.
PORT HEALTH
(See table 29)
47. The Port Health Administration continued its routine duties in respect of prevention of the introduction of quarantinable infectious diseases, the sanitary control of ports of entry, the provisions of the International Sanitary Regulations and a regular exchange of epidemi- ological information with the World Health Organization as well as with ports and airports in other countries.
