Dengue has emerged as a worldwide problem since the 1950s, and is endemic in Puerto Rico and in Latin America, Southeast Asia and the Pacific islands. It is a leading cause of death in those areas.
Dengue is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. albopictus. This mosquito also transmits chikungunya, yellow fever and Zika infection. Dengue is widespread throughout the tropics, with local variations in risk influenced by rainfall, temperature and unplanned rapid urbanization.
As many as 400 million people are infected yearly. It is caused by any one of four related viruses transmitted by mosquitoes. There are not yet any vaccines to prevent infection with dengue virus and the most effective protective measures are those that avoid mosquito bites. When infected, early recognition and prompt supportive treatment can substantially lower the risk of medical complications and death.
Studies regarding the prevalence of dengue estimate that 3.9 billion people, in 128 countries, are at risk of infection with dengue viruses.

Critical to prevention and treatment of dengue is the availability of social and behavior change communication (SBCC) tools and materials. Service providers need to be aware of symptoms, explain treatment protocols, and inform the patient and family members about care of the patient. The general public needs to know about the vital importance of prevention techniques, and how to recognize symptoms in others.
The Health COMpass presents below a range of SBCC tools and project materials created for dengue, and we welcome our users to submit their own materials to our collection by registering and then contributing online.
