Dengue fever, a viral infection spread by the Aedes Aegypti mosquito, is a serious health problem in many Central American and Caribbean countries. Its symptoms include high fever, nausea, rashes, backache and headaches. Most mainstream dengue cases are not fatal, but the hemorrhagic variant, which causes severe internal bleeding as blood vessels collapse, kills one in 20 of those infected.
The World Health Organization said the only way to fight dengue was to stamp out mosquitoes, which reproduce in bodies of water from puddles to lakes and reservoirs. Some 50 million people are infected with dengue each year, most of them in the tropical regions.
