The Food and Environmental Hygiene Department (FEHD) today (December 10) announced that the monthly gravidtrap index (MGI) for Aedes albopictus mosquitoes in November was 0.9 per cent, lower than the 2.2 per cent recorded in October. This reflects the continued efforts by relevant government departments to intensify mosquito prevention and elimination operations, resulting in the improvement of the overall mosquito infestation situation this month. In addition, the FEHD has strengthened the dissemination of information on the gravidtrap index for Aedes albopictus mosquitoes so that more citizens can quickly grasp the mosquito infestation situation. The department will continue its mosquito control work to further reduce the risk of transmission of chikungunya fever (CF) and dengue fever (DF).
In November, all 64 survey areas recorded an area gravidtrap index (AGI) lower than the alert level of 20 per cent. The decreases in the MGI and the AGI are attributable to the continuous and intensified mosquito prevention and elimination operations by various government departments and stakeholders, and may also have been affected by factors such as weather. The monthly rainfall was 7.0 millimetres in November, showing a substantial decrease from the 31.2mm in October and 528.7mm in September. Overall, the MGI for Aedes albopictus mosquitoes in November was 0.9 per cent, at Level 1 (indicating the distribution of Aedes albopictus mosquitoes in the survey areas was not extensive). Relevant departments and stakeholders will persistently intensify mosquito prevention and elimination operations.
