With the increase of dengue cases in Singapore in recent years, National Environment Agency (NEA) is addressing these concerns by collaborating with Smart Communities in a public service project to raise awareness of dengue clusters, health risks and prevention through SMS and email alerts. It is part of a new initiative by NEA to equip the public with timely information so that they can take immediate steps to keep themselves dengue free. The x-Dengue initiative is part of NEA's efforts to enhance public outreach efforts on dengue by providing useful, timely and relevant alerts and customized information on dengue clusters. People can now get free SMS alerts on new dengue clusters in areas they frequent, such as neighborhoods and workplaces. They will also receive alerts on the severity of a dengue cluster and its closure. Previously, the public had to check the official NEA website regularly to receive these updates. The information, which is refreshed daily, reflects a dengue cluster that is within 150 metres of a specific location. Under one user's account, up to eight places and five other users' telephone numbers can be registered. Alerts are also sent if the dengue cluster grows beyond 10 cases - for every five new cases. In addition, text messages provide a link to website for more tips on dengue prevention. Users can view information about a specific location by keying in the postal code and even request for SMS alerts for that particular location. Subscription to this service is free as the SMS costs are borne by private telecommunication companies as part of their Corporate Social Responsibility efforts.
