Judging from the Hospital admissions this disease was slightly less prevalent than last year. The cases admitted to the Government Hospitals for the last six years were as follows:-
1925 1,142 1926 970 1927 670 1928 485 1929 653 1930 535Of the 535 cases admitted during the year 370 were benign tertian, 163 sub-tertian, 2 quartan.
The incidence among the police in the New Territories for the same period was:-
1925 1,205 1926 877 1927 428 1928 278 1929 265 1930 258Many of the Police Stations are screened and every man is provided with a mosquito curtain. Prophylactic Quinine is issued and the living rooms are regularly sprayed with an insecticide to repel mosquitoes and to kill those that may be present.
The total number of deaths attributed to Malaria was 515 or 3.1 per cent of the whole: the death rate per mille population was 0.47 as compared with 0.40 for 1929. The lowness of the rate is of course due to the fact that the majority of the population being outside the zone of the Malaria carrying anophelines are not subject to risks of attack. A number of localities outside the town are reputed to be malarious but at present there are few figures to allow an estimate to be made of the amount.
Dengue.--Dengue is endemic in Hong Kong and from time to time reaches epidemic form. There was nothing in the way of an epidemic in 1930.
Filariasis.—The disease probably exists but there are no figures on which to estimate sickness and death rates. Cases of Elephantiasis are rare.
