Hong Kong mosquito infestation hits warning level

If you’ve been having mosquito bites, you probably live in one of nine Hong Kong districts with serious infestation.

A monthly index measuring the extent of the distribution of aedine mosquitoes surged to 12 percent in May from 1.8 percent in April across Hong Kong.

However, nine of 44 districts hit the third level of a four-stage warning system with a reading above 20 percent, the Food and Environmental Hygiene Department said Monday.   

These are Tseung Kwan O (45.6 percent), Sai Wan (22.6 percent), Sham Shui Po East (23.6 percent), Lam Tin (32.7 percent), Sai Kung city (30.6 percent), Yuen Long Town Centre (20 percent), Tsuen Wan Town Centre (25.5 percent), northern Kwai Chung (20.4 percent) and Tsing Yi (22.8 percent).

Sai Kung district councilor Kan Siu-kei said the situation is quite serious in the Hong Kong velodrome in Tsueng Kwan O, exacerbated by stagnant water where mosquitoes breed, Sky Post reported Tuesday.

The district council has urged the government to send mosquito exterminators more frequently.

Since 2011, the government has been monitoring 44 districts for its monthly ovitrap and area ovitrap indices. The former is the monthly average of all area readings of infestation by the aedes albopictus mosquito, commonly known as tiger mosquito, which can cause blood-borne diseases such as yellow fever and dengue fever.
