Malaysia is having a debate about a new proposal by the Public Works Department to require the installation of insect screens in all building openings. The screens are aimed at preventing the entry of Aedes mosquitoes that are vectors of Dengue. Window screens can prevent Dengue transmission by preventing infected mosquitoes from biting healthy people when they are indoors as well as preventing mosquitoes from acquiring Dengue by biting people who are ill with the disease. Window screens have proved useful all over the world in reducing mosquito vectored disease.
The debate? Some think the cost of the screens are too high.
