The Food & Environmental Hygiene Department today released the first batch of figures for August in the gravidtrap index for Aedes albopictus.

Among the 13 areas surveyed, the gravidtrap index in So Kwun Wat, Tuen Mun District reached 16.4%, while the index recorded in the other 12 areas ranged from 0% to 7.4%.

The density index for the 13 areas was released along with the gravidtrap index.

In response to the recent chikungunya fever situation, the department has activated a mechanism that strengthens mosquito control work in areas where the gravidtrap index is between 10% and 20%. Previously the mechanism was only activated when the index reaches 20% or above.

It will collaborate with other departments and stakeholders to identify locations with high mosquito infestation, and carry out intensive and targeted mosquito control measures.
