Dengue Hemorrhagic Fever(DHF) is actually an old virus that is considered to be one of the most deadliest the world over due to their ability to jump species. Spread by the Aedes Aegypti mosquito, that is differentiated by it’s daytime feeding habits, it has silently killed millions the world over. The incubation period is short accompanied by severe fever that usually lasts three days, after which, without proper monitoring and care death is sure to occur. Mostly restricted to areas that are in the tropics zone due to the inability of its host to survive in cold weather. Outbreaks have been well documented and a cure is still out of sight. The disease is however being tackled from different angles, one of them targets the disease at its source, the mosquito which can be infected with a virus that halves its lifespan thus lessening its ability to spread it by half. The danger came when man invented mass travel wherein people and machines could transport the disease carrying mosquitoes all over the globe.
