Li Ma Hang Lead Mine (close to Frontier.)
73. A request was received from Dr. H. Talbot for a malaria survey around the residential area on the mine. Larval surveys were made from the 17th to the 20th November. As the rice fields and most of the ditches were dry, no larvae were found in them. In one stream 12 A. maculatus were found, in another 95 A. maculatus, 31 A. minimus, 26 A. hyrcanus.
74. No mosquitoes were caught in the quarters of the labourers engaged on the site, but 29 A. minimus, 5 A. jeyporiensis, 2 A. hyrcanus were collected in adjacent villages. All were dissected, two of the A. minimus were found infected.
75. Owing to the large amount of hill paddy near the Camp, a certain amount of which lies within Chinese Territory, anti-larval measures would be difficult to carry out. It is understood that the coolies will be housed in brick-built mosquito-proofed structures.
Fort Street. (North Point. H.K.)
76. The occurrence of a case of malaria at No. 26 Fort Street was notified in December. From enquiries made it was ascertained that the disease was contracted at the above address. The diagnosis had been made by blood examination. Breeding places of A. jeyporiensis and of A. minimus had been found previously in this neighbourhood.
Mount Cameron (The Peak).
77. An outbreak of malaria occurred towards the end of the year.
On the 3rd and 14th December blood smears were taken from fifty-three residents mostly house servants. Three smears contained parasites. One servant in whose blood no parasites were found, had been previously treated in Hospital for malaria, another servant whose blood was not taken, had also been treated.
78. By the 17th December six Europeans were said to have contracted the disease.
79. Larval surveys were made in adjoining streams, from the 11th December onwards, many larvae of A. minimus were found in one which runs from the Aqueduct east of Bennett's Hill to Island Road,
80. Arrangements were made for the clearing and oiling of streams harbouring A. minimus.
Aberdeen Industrial School,
81. Complaints were received on the 10th December of the occurrence of malaria cases from November onwards.
