surgical, orthopaedic or medical treatment. The clinics also provide medical social work, contact tracing and supervisory services and under- take surveys of selected groups, such as Government employees and prisoners, in co-operation with the Radiological Service. In certain cases, where the family depend on the patient's carnings and no other way can be found to maintain the dependants during his hospitalization, a regular financial grant can be made.
41. Increasing attention is being paid to the public health aspects of tuberculosis. 73 Health Auxiliaries, whose main duties consist of contact tracing and home visiting, are attached to the Chest Service: these Health Auxiliaries are supervised by one Health Sister and six Health Visitors. Regular attendance for out-patient chemotherapy is of paramount importance and considerable emphasis is placed on follow- up of defaulters and on ensuring that contacts are examined.
42. The high incidence of primary and secondary drug resistance in Hong Kong has been demonstrated by research undertaken in conjunc- tion with the Medical Research Council in Britain. Results of these investigations indicated that the level of drug resistance in Hong Kong was probably the highest in the world, 40% of the organisms inves- tigated showing a resistance to one or more of the first-line drugs commonly used in ambulatory chemotherapy. A register of resistant cases is kept at the main clinics. During the year a total of 337 cases were registered, of which 280 were bacteriologically resistant to at least one drug and the remainder were resistant clinically; these patients were entered on the waiting list for admission to hospital for treatment with 'second-line" drugs.
43. The work of bospitals dealing with tuberculosis cases is reviewed elsewhere in this report.

44. The incidence of early infectious syphilis showed a considerable reduction in 1966, marking the third consecutive year of reduction. The number of latent syphilitic cases was about the same as in the previous year while the incidence of gonorrhoea showed a slight increase. It is encouraging to note that the incidence in the teenage group of the population has not risen in the manner experienced in many other parts of the world. The trends over the past ten years are illustrated in Figures 8 to 10.
