Dengue is one of the most common mosquito-borne viral disease of humans. Dengue mostly occurs in the tropical and sub-tropical areas of the world. Outbreaks of dengue fever usually occur in the rainy season.

Dengue viruses are transmitted to humans through the bites of a striped Aedes aegypti mosquito that has previously bitten an infected person. Dengue does not spread directly from person to person. It is only spread through the bite of an infected mosquito.

The disease itself is rarely fatal, but a more serious complication, Dengue Hemorrhagic Fever is far more dangerous. Dengue Hemorrhagic Fever is a more severe and potentially deadly form of the disease in which  bleeding and sometimes shock occurs. It can be fatal if unrecognised and not properly treated. Nowadays many people suffer from dengue. Dengue fever is an infectious disease carried by mosquitoes and caused by any four related dengue viruses. This disease used to be called break bone fever because it sometimes causes severe joint and muscle pain. Dengue fever is a quite dangerous febrile disease can be found in the tropics and water stagnant outdoors . Dengue fever is transmitted by Aedes Aegypti mosquito, which also transmits diseases as yellow fever.

 Dengue has frightened Malaysians country. Malaysia released about 6,000 genetically modified mosquitoes into a forest in the first experiment of its kind in Asia aimed at curbing dengue fever,
The field test is meant to pave the way for the use of genetically engineered Aedes aegypti male mosquitoes to mate with females and produce no offspring or ones with shorter lives, thus curtailing the mosquito population. Only female Aedes aegypti mosquitoes spread dengue fever, which killed 134 people in Malaysia last year.

Government authorities have tried to allay the concerns by saying they are conducting small-scale research and will not rush into any widespread release of mosquitoes. The Malaysian government-run Institute for Medical Research said it released about 6,000 sterile male lab mosquitoes in an uninhabited forest area in eastern .


     The symptoms of dengue fever are severe headache, pain in the muscles and joints, and rash that can be described as small red spots. Some patients experience gastritis, diarrhea, vomiting and abdominal pain. Dengue fever usually starts suddenly with a high fever, headache, pain behind the eyes, and pain in the muscles and joints. A rash usually appears 3 to 4 days after the start of the fever.Nausea, vomiting and loss of appetite are common.

    Each type of the dengue virus is re-emerging worldwide.Global warming has shown to be a major
contributor to the spread of dengue fever. Global warming can cause dry spells in some countries and increased rainfall and humidity in others. The dry spells reduce small medium bodies of water like springs and ponds to small puddles that become potential breeding ground for mosquitoes. Likewise increased rainfall and humidity also leads to collection of water that affords possible breeding grounds for mosquitoes.

    Dengue is spread by the Aedes Aegypti, a domestic, day biting mosquito that prefers to bite humans. They breed in clean water. Currently there is no vaccine available to prevent dengue. Scientists are also trying to invent a vaccine against dengue fever, but the researches are only at the stage of experiments yet. The only treatment is rest and intake of plenty of fluids like water, juices, milk and many more.

    To prevent the spread of dengue fever, you must first prevent the breeding of its vector, the Aedes mosquito. The Aedes mosquito is easily identifiable by the distinctive black and white stripes on its body. It prefers to breed in clean, stagnant water easily found in our homes. You can get rid of the Aedes mosquito by frequently checking and removing stagnant water in your premises.

     At present, the only method of preventing and controlling dengue fever is to eradicate the mosquito population. They are a number of ways to combat the vector mosquitoes.First,Improved water storage practices. Cover all containers to prevent egg laying female mosquitoes access to it. Implement proper solid waste disposal.Eliminate any sources that may collect water such as tins, bottles, plastic food containers and old tires. Mosquitoes breed easily in any source of standing water.Then, appropriate insecticides, such as larvicide's can be added to water containers and man-made ponds. The insecticides can prevent mosquitoes breeding for several weeks. However, they must be re-applied as per directions.You have to always clean and check drains to ensure they are not blocked especially during the rainy season. Breed small mosquito-eating fishes in an artificial pond to eradicate the mosquito larvae.In addition to the above, there are a number of factors to help prevent the mosquito being attracted to human prey.Avoid wearing dark and tight clothing because mosquitoes are attracted to dark colours. Wear loose, white and long clothes, which cover the whole body. Mosquitoes find it difficult to bite through loose clothes than tight fitting clothes.

     Environmental conditions, It is suggested to sleep under mosquito netting or in a room which has mosquito screens on the windows. Mosquitoes are unlikely to bite in an air-conditioned room and under strong fans. Mosquito coils are also useful to help prevent mosquitoes from entering the room.
pply mosquito repellants.Avoid reduce outdoor activities during morning and late afternoon because Aedes mosquitoes are daytime feeders.
