Ovitrap index falls

January 26, 2015

The monthly ovitrap index for December dropped to 0.1% from 0.4% in November.

 

The Food & Environmental Hygiene Department said that among the 44 areas surveyed last month, positive ovitrap indices were recorded in three of them, ranging from 1.8% to 1.9%, with the highest levels in Tai Po and Sheung Shui.

 

For port areas, the monthly ovitrap index for December fell to zero from 0.1% in November.

 

The ovitrap indices reflect the prevalence of Aedes albopictus, a mosquito vector for Dengue fever transmission.
