Dengue and Its Prevention Dengue fever is a disease caused by a family of viruses that are transmitted by mosquitoes. It is an acute illness of sudden onset that usually follows a benign course with symptoms such as headache‚ fever‚ exhaustion‚ severe muscle and joint pain‚ swollen glands (lymphadenopathy)‚ and rash. The presence (the "dengue triad") of fever‚ rash‚ and headache (and other pains) is particularly characteristic of dengue. Other signs of dengue fever include bleeding gums

dengue fever is on the rise worldwide‚ and in some areas of Asia‚ complications of the disease are a leading cause of serious illness and death in children. Body I. Dengue viruses are transmitted between humans by the bite of an infected Aedes mosquito. A. Mosquitoes pick up a dengue virus when they bite a human who is already infected with the virus. 1. The mosquito then carries it in its own blood and spreads it when it bites other humans. 2. After a dengue virus

The teachers have to keep an eye on the students to avoid them from playing truant fro these cleaning operations. Teachers also play an enormous role in this disease prevention. They need to create awareness through exhibitions such as “Meet The Aedes”‚ “Know About Mosquitoes” and “Dengue The Deadly Disease” must be held at schools. Through these exhibitions‚ students will be exposed about dengue. Teachers also must send students to anti dengue seminars. During these seminars‚ students will be thought

estimates there may be 50-100 million dengue infections globally every year‚ with two-fifths of the world population‚ or 2.5 billion people‚ at risk of this mosquito-borne infectious disease. Dengue fever is spread through the bite of an infected Aedes aegypti mosquito. The first symptom of the disease appears in 5-7 days after the mosquito bit a healthy person. It is possible to become infected by dengue multiple times because the virus has four different serotypes. The symptoms are high fever‚

estimated 50 million to 100 million in the tropics (Epstein‚ 2000). The virus has four antigenically related serotypes‚ which are named DEN-1‚ DEN-2‚ DEN-3‚ and DEN-4. Each dengue serotype is a variation of the flavivrus genus. Dengue is spread by the aedes aegypti‚ a domestic‚ day-biting mosquito that prefers to bite humans. Currently‚ there is no vaccine available to prevent dengue. Each type of the dengue virus is re-emerging worldwide‚ especially in the Western Hemisphere. Research has shown that

uncontrolled population growth etc. The changing patterns of climate have provided a favorable environment for vectors to feed and breed. Urbanization and uncontrolled population growth in urban and peri–urban areas have also favored the breeding of Aedes aegypti. Rapid population growth affects public services such as providing safe drinking water. Thus‚ people take up unsafe water storage practices. Also the recent increase in air travel has resulted in rapid dispersal of virus and exchange of different

Chikungunya Fact sheet N°327 March 2008 ________________________________________ Key facts • Chikungunya is a viral disease that is spread by mosquitoes. It causes fever and severe joint pain. Other symptoms include muscle pain‚ headache‚ nausea‚ fatigue and rash. • The disease shares some clinical signs with dengue‚ and can be misdiagnosed in areas where dengue is common. • There is no cure for the disease. Treatment is focused on relieving the symptoms. • The proximity of mosquito breeding

Tucson‚ Ariz.‚ and Key West‚ Fla.‚ each have had sustained populations of Aedes aegypti‚ a dengue-carrying mosquito‚ for some 20 years. And yet‚ whereas the virus rippled through southern Florida‚ documented cases in Tucson are still unknown. The interest is not just academic—answers could help avert future bouts of the virus
