Of the five Indian police stationed at Shing Mun, three suffered from malaria and were treated there, neither of the two Chinese contracted the disease.
98. Table XV gives the estimated population of the Labour Force, month by month, its distribution according to race, the number of cases treated due to malaria and to all causes, also the results of examination of blood films for malaria. The figures have been supplied by the Resident Medical Officer.
99. The malaria case rate was high in January; dropped from February onwards but rose again in July, and remained at a comparatively high level for the remainder of the year.
100. From July onwards the A. jeyporiensis catches increased considerably, and those of A. minimus from October onwards.
101. Table XVI gives the monthly malaria case rates for the years 1933 and 1934 and the annual malaria case rates for 1933 and 1934. It will be seen that the annual rates for 1934 is one quarter that for 1933.
(2) Site of New Government Civil Hospital (at junction of Islands and Sassoon Roads).
102. Mosquito catches were made in the four matsheds which housed about 425 labourers employed on levelling the site of this Hospital. From January until June it was only considered necessary to make monthly visits, after June weekly visits were paid as incidence of malaria is usually higher from that time onwards. The Inspector engaged in the catching took thick and thin films of any persons found sick in the matsheds. In the course of 30 visits, only three Anophelines (A. minimus) were caught, and these in November and December. Four blood films were taken, no parasites were found in them and no infection was found in the mosquitoes.
103. Several surveys have been done within the circle of half mile radius from the site, from 1931 onwards. Larvae of A. maculatus have always been found in abundance but few larvae of A. minimus, except when the surveys were done in the colder months, when they were found in comparatively large numbers in a small sector of the circle in the neighbourhood of Mount Davis Road. In this small sector 19 out of 26 children or 73% examined in 1931 had enlarged spleens.
104. In the remaining sector of the half mile circle 124 children were examined, three or 2.4% had enlarged spleens, this sector contains numerous cattle and pigs the property of the Dairy Farm Co..
