97. The incidence among the police of the New Territories for the same period was:-
1925 1926 1927 1928 1929 1930 1931 1932 1,205 877 428 278 265 258 148 55 102 193398. Many of the Police Stations are screened and every man is provided with a mosquito net. Prophylactic quinine is issued and the living rooms are regularly sprayed with an insecticide in an endeavour to kill any adult mosquitoes that may be present. The police on night patrols are of course liable to infection.
99. The total number of deaths attributed to malaria was 414, giving a death rate of 0.50 per mille for the Colony. The lowness of the rate is, of course, due to the fact that the great majority of the population living in the drained urban areas are outside the zone of flight of malaria carrying anophelines and, therefore, not subject to risks of attack.
DENGUE.
100. There was no epidemic of this disease during the year and only a few cases came under the notice of the Medical Officers.
FILARIASIS.
101. Researches carried out by the Malariologist show that a higher percentage of the people harbour micro-filaria in their blood than was formerly supposed. A number of mosquitoes, dissected for malaria, had filaria in their tissues. Twenty-two cases of elephantiasis were treated in the Government Hospitals and three in the Chinese Hospitals. Four cases of Chyluria were reported from the Chinese Hospitals.
Infectious Diseases.
102. The infectious diseases of the Colony may, for convenience, be classed into those which are notifiable and those which are not.
103. The most important of the non-notifiable infectious diseases is Pulmonary Tuberculosis. Leprosy is notifiable under the Leprosy Ordinance 1910 but not under the Public Health and Buildings Ordinance.
