73. Buildings erected to house labourers on temporary pro- jects are a serious problem. Most prominent among these are the appalling shacks put up by illegal miners working the scattered wolfram deposits throughout the New Territories. These have not only risked their own health by their insanitary mode of living, but have also caused a serious danger to the health of others through the contamination of water supplies and interference with irrigation in general. The scattered situation of these mines and the lack of firm financial prospects for the miners are two of the reasons which make control extremely difficult. At the moment, however, the position is generally im- proving.
74. Considerable work has been done to keep the areas around military establishments free from fly and mosquito nuisance and fair success has been attained. The problem is not eased by the fact that many of the nuisances arise from con- tractors working in connexion with the camps themselves.
75. A new market has been built by private enterprise at Shatin and is a great benefit to the community."
COMMUNICABLE DISEASES
76. In 1951 there was no case of cholera, plague, smallpox, epidemic typhus or yellow fever,
77. Only 2 cases of scrub typhus fever were notified from among the troops but the disease is neither epidemic nor endemic.
78. For the fifth year in succession the Colony has been free from any major epidemic.
79. During the year 1951, there was no case of rabies, human or animal. The case registered in March 1951 actually occurred on the 24th of December 1950 in Tai Po, N.T., and the laboratory test was not confirmed until the 16th of March 1951.

Notifiable dissuses
There were 1,024 cases with 134 deaths, in 1951 as against 907 cases with 160 deaths, in 1950. The incidence of the disease has been steadily rising since 1946.
83. In spite of repeated efforts, no focus of infection could be found. It is believed that carriers are the source of infection. Data showed that squatter populations had a higher percentage in both incidence and deaths than the community at large. The disease continued to be particularly fatal to young male adults.
84. Dysenteries.
While bacillary dysentery showed a 47% increase in incidence, amoebiasis registered a 13% decrease. There were 154 cases of amoebiasis with 9 deaths and 371 cases of bacillary dysentery with 28 deaths during the year, as against 177 cases
