114. A Senior Port Health Inspector assisted by two Health Inspectors dealt with all deratting and disinsecting aspects of Fort Health work. Cyanide and sulphur fumigation were undertaken by the port. 19 Vessels were fumigated with eyanide, 72 with sulphur, and 152 exemptions were granted for 1.951.
115. The port was free of any epidemic of quarantinable disease during the year. However, one imported case of small- pox, and one local case of smallpox, which was notified on 17th January, 1952 and 18th February, 1952 respectively, were recorded.
116. Due to the absence of accurate epidemioligical intelli- gence from the Chinese mainland all cargo originating from areas in China where plague is endemic had to be disinsected as a precaution against the introduction of plague-infected fleas in the cargo.
117. 82,816 passengers, 191,838 crew, and 3,742 vessels were inspected during the year 1951 as against 731,148 passengers, 537,991 crew and 13,781 vessels in 1950. (The 18,781 included small craft which arrived from Macao and the river ports in the Kwangtung Province).
118. Due to travel restrictions and the limitation on the quota permitted for contracted labourers, the total number of emigrants inspected during the past year was 13,487 as against 25,038 for 1950.
119. The number of Bills of Health issued during the calendar year 1951 was 2,769.
120. Although air passenger traffic had not increased much, 32,669 passengers as compared with 32,177 in 1950, were medically inspected. All passengers and crew of arriving air- craft were medically inspected, and the International Civil Avia- tion Organization's recommendation regarding the routine spraying of aircraft was insisted upon.

SOCIAL HYGIENE
121. For the greater part of the year there were 7 Doctors, one Technical Assistant, 12 Nurses, and 6 Dressers on this work. In the early part of 1962, 4 Social Hygiene Health Visitors were recruited for contact tracing as a result of the Venereal Diseases Ordinance.
122. There is one Hospital for female patients with 20 beds and 8 cots, and 6 clinics of which 3 are for males and 3 for females. The clinics run full time and evening sessions are arranged for office workers.
123. In addition a great amount of work has been done in improving the control of venereal disease in the prisons; with the newer drugs giving more rapid results there is real hope for clearing up this problem.
124. As a result of the presence of large numbers of Army personnel in the New Territories it has been necessary to develop anti-venereal disease work in this area and special clinica have been set up.
125. A close link has been established with ante-natal, infant welfare and maternity services. Blood specimens are taken as a routine at these clinics. 24,375 specimens were examined last year, and 7.5% were positive to the Kahu Teat and this may be assumed to be a fair sample of incidence of venereal disease. One disturbing feature is that of the positives only 31.8% came for adequate treatment.
126. Home visits are being increased to educate and per- auade infected mothers to attend for treatment.
127. A record number of 17,934 new cases of which 40% were females, was recorded in 1951 as compared with 13,524 in 1950. The total attendance of all patients was 152,294.
