The monthly ovitrap index for July has risen to 23.1% from 20.7% in June, the Food & Environmental Hygiene Department says.

The area ovitrap indices for Diamond Hill, Sheung Shui and Tai Po reached 70.9%, 68.5% and 61.8%. The index for port areas, however, fell from 3.2% to 2.9%.

In view of rising ovitrap indices the inter-departmental anti-mosquito response mechanism has been activated in all districts. Government departments have bolstered mosquito control measures in specific areas and increasing the number of operations to contain the mosquito problem.

The department will launch the third phase of the anti-mosquito campaign August 20. During the eight-week campaign, government departments and public bodies will enhance anti-mosquito operations and publicity activities throughout the city.
