Evolution of dengue epidemic “at a critical juncture”: Balakrishnan – Channel NewsAsiaPosted: June 11, 2013
There are four contributing factors to the current epidemic. Firstly, the Aedes mosquito is now predominant across the island. Secondly, the currently circulating dengue virus – Dengue Serotype 1 – has higher epidemic potential. Thirdly, the low immunity amongst the population makes people more vulnerable. Lastly, the hot and wet weather accelerates the life cycle of the Aedes mosquito and increases the likelihood of stagnant water accumulating.
Dr Balakrishnan said: “Our numbers are still rising and we are going into a peak dengue season so we cannot afford to lose control at this stage.”
The National Environment Agency (NEA) will step up surveillance and inspection.
It will recruit another 300 officers over the next two months so that all premises in dengue clusters can be checked within a week.
Officers will be equipped with a new aerosol spray and it will be applied to dark corners of homes. The spray is said to last in the air longer and is more deadly to mosquitoes.
1.2 million insect repellents will also be distributed for free to households in dengue clusters.
Homes remain the top culprit for breeding spots.
