Dengue safe community

Efforts to protect against dengue are more effective when whole communities are involved. In some parts of the world, for example, in Singapore and Cuba, communities have worked together and successfully reduced the spread of dengue.

The mosquitoes that transmit dengue breed in standing water. Getting rid of containers that hold water, or fitting lids or covers on them, is an effective way to reduce the number of mosquitoes.

Identifying sites where mosquitoes breed and removing them, or cleaning and treating with insecticides also works.

Being prepared for dengue outbreaks and having a plan can reduce the spread of the disease, so fewer people become ill with dengue. Training community leaders and healthcare workers, and talking to neighbors, friends and family about the benefits of cleaning up public spaces to reduce mosquito breeding can also make a difference.2

In Singapore a government-led traffic light system tells residents about the number of people becoming ill with dengue in their community. It reminds them what to do to help reduce the risk of infection in red or yellow zones and to remain vigilant in green zones.3 

In Vietnam, a microscopic plankton-like creature which feeds on newly hatched mosquito larvae has been introduced to water tanks and water jars. This has succeeded in eliminating dengue in many areas.
