The government says it will ramp up efforts to kill off mosquitoes on Cheung Chau where residents are continuing to come down with dengue fever, with pest control officers to be sent to every home and school on the island.
Along with Lion Rock Park in Wong Tai Sin, Cheung Chau has been identified as a hotspot for the unprecedented dengue outbreak Hong Kong is experiencing this summer.
Workers have already been disinfecting areas within 500 metres of each Cheung Chau patient's home, but the authorities have decided this isn't enough.
Chief Secretary Matthew Cheung said the enhanced measures will begin on Monday, with workers spraying chemicals to kill mosquitoes at all homes and schools.
He stressed, however, that the situation is under control, even if more sporadic cases of dengue are possible on the island.
But some business owners on Cheung Chau are far from happy with the recent developments, with a shop owner at the ferry pier telling RTHK that the tourist crowds over the weekend were only about half as large as normal.
Another shopkeeper selling snacks said his business was down about 80 percent. He said anti-mosquito measures should have been carried out before residents and visitors starting catching dengue.
"There really are fewer people around. This is like wintertime. I mean there's nobody coming to Cheung Chau during winter. That's how bad it is. But I guess it's okay. The important thing is everybody is healthy," he said.
But the outbreak wasn't putting everyone off from going to Cheung Chau, with one visitor adamant that she wasn't bothered by the dengue risk.
"We've got anti-mosquito sprays, patches. We plan on going up the hills around the island. We aren't too worried. Because we've done enough mosquito prevention measures, we should be okay," she said.
As of Sunday lunchtime, 26 people had been diagnosed with dengue fever in an outbreak that began earlier this month. In almost all of the cases, those infected were known to have recently been either on Cheung Chau, or at Wong Tai Sin's Lion Rock Park.
