MALARIA BUREAU

46. The Malaria Bureau continued routine control operations for the protection of the population in the main urban areas of Hong Kong Island and Kowloon and also in certain circumscribed rural areas of the New Territories at a cost of 35 cents per head of population protect- ed. In addition to monitoring of the control programme, malariometric, mosquito and parasite surveys were also pursued by field and laboratory staff.

47. The incidence of malaria continued to decline, notifications being approximately one-half of those in 1963; this can be attributed most probably to the prolonged drought followed by a period of extremely heavy rainfall, a meteorological pattem which must inevitably have played havoc with the life-cycle of the stream-breeding anophelines which are the main transmitters of the disease in Hong Kong. The incidence of natural malaria transmission in the controlled areas continued to be virtually nil.

gradually since 1958 in general conformity with world statistics, showed a reduction; although it is as yet too early to say whether or not this is anything but & temporary phenomenon, it is encouraging to note that the incidence in the teenage group of the population has not risen in the manner experienced in many other parts of the world. The trends over the past nine years are illustrated in Figures 10 to 12.
