New Territories Police Stations.
500. These have been inspected periodically by the M.O. i/c. Kowloon and New Territories, and, in addition, the A.M.O.'s visit them once a month.
501. 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 which may be present. The men on night patrol are of course exposed to the bites of mosquitoes. A table showing the incidence of malaria amongst the whole police force will be found in Appendix B.
502. The experiment in the use of Quino-plasmoquine at T'sun Wan Police Station, which was started last year, has been continued, and compared with the incidence of malaria there in past years, it has justified itself. There were 8 cases of malaria reported there during the year, but it was not possible to be certain in all cases that the infection had been contracted at the station. Whether it is that there is less evasion when tablets are used than when the liquid form of quinine is used, I am not prepared to say, but the incidence of malaria at this station since the introduction of this prophylactic treatment has diminished.
