Ovitrap readings for dengue threat increase The monthly average ovitrap index for September shot up to 8.3 per cent from 3.9 per cent in August, the Food and Environmental Hygiene Department said. This came after the department launched an investigation into allegations that some ovitraps, which monitor numbers of the mosquito that carries dengue fever, had been tampered with. The index in 12 areas exceeded 10 per cent. Diamond Hill, Sham Shui Po East and Wong Tai Sin Central were the top three, with the index reaching 19.1 per cent, 18.2 per cent and 18 per cent respectively. Officials conduct special operations when the readings hit 20 per cent.
