47. Case finding continued at a high level. particularly in ante-natal cases where an initial positive serology rate of 1.0% was observed. Of the 104 positive cases referred from ante-natal clinics, only 90 cases, ie., 86.5% were actually suffering from syphilis. Contact tracing, particularly of infectious syphilis, was continued.
Leprosy
48. New cases of leprosy treated numbered 135, representing a rate of 3.4 per 100,000 of population. Tuberculoid manifestations comprised $1.8% of total cases. Of the infectious cases 70 were admitted to the Hay Ling Chau Leprosarium maintained by the Leprosy Mission- Hong Kong Auxiliary, with which the Social Hygiene Service maintains close liaison.
49. During recent years there has been some advance in overcoming the prejudice against employment of cured leprosy patients, and to this end great attention is paid by the Service to the prevention of dis- abilities in tuberculoid cases.
Dermatology
50. The incidence of skin diseases is shown in Table 31. There was a very low incidence of skin cancers. The total number of new
18
cases rose by about 4.3% more than the previous year and 157% more than ten years ago. The types of skin diseases in 1970 were similar to previous year, the six commonest types being eczema, fungal infections, contact dermatitis, lichen simplex, urticaria and warts.
PORT HEALTH (Table 33)
51. The Port Health Service continued to fulfil its routine duties in connection with the prevention of the introduction of quarantinable communicable diseases, the sanitary control of port and airport areas, the provision of facilities as required by the International Health Regulations, and a regular exchange of epidemiological information with the World Health Organization as well as with ports and airports in other countries.
52. With the increasing importance of Hong Kong as a tourist and an international transit centre, the work of the Service has steadily mounted during the recent years. This has not only been due to the increase of shipping entering the port resulting in the necessity of maintaining a full 24-hour daily quarantine service, but to a vast increase in air traffic at Kai Tak Airport. The Service is also responsible for the Port Health work in connection with travelling between Macau, Kwangtung province and Hong Kong, while particular attention is paid to vessels and aircraft from plague-infected areas, as well as to food imports from cholera-infected places.
DISTRICT MIDWIFERY SERVICE (Table 34)
53. Nearly all births took place in institutions, either hospitals or maternity homes. Delivery in hospitals gradually increases as all cases are carefully screened, and any high risk cases are referred to the specialist units for further management. Thus, only 18% of the births were attended by the Government District Midwives, and midwives in private practice attended another 19%, as compared with 20% and 22% respectively in 1969. The remainder of the births took place in Government, Government-subsidized and private hospitals.
54. During the year, there was no change in the number of Govern- ment district maternity homes. On the other hand 2 new private maternity homes were registered, while & old ones were voluntary sus- pended, with a reduction of 58 beds. During the past 5 years there
