The Best way to Prevent Dengue Fever is to Take Special Precautions

Dengue fever presents with sudden onset of high fever, severe headache, eye pain, bone and muscle pain, and nausea and vomiting. Rash generally occurs three or four days later. The disease may present in a more severe form, dengue hemorrhagic fever, with bleeding and shock, which may be fatal.

Dengue fever is a viral disease transmitted by mosquitoes. It is commonly found in tropical and subtropical regions including South East Asia, South Asia, the Pacific area, Africa and Central America.

 The best way to prevent dengue fever is to take special precautions to avoid contact with mosquitoes. There are many methods of mosquito control, experts now recommended an "Integrated approach" that is an approach which tries to combine one or more methods with a view to obtaining maximum results with minimum input and also to prevent environmental pollution with toxic chemicals and development of insecticide resistance.

Prevention and Control

• At present, the only method of preventing and controlling dengue fever is to eradicate the mosquito population. There are number of ways to combat the vector mosquitoes:
• 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.
• 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.
• 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.
• 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.
• Avoid reduce outdoor activities during morning and late afternoon because Aedes mosquitoes are daytime feeders.
• Change at least once a week the water in flower vases and saucers of potted plants to prevent breeding of mosquito. The use of saucers should be avoided whenever possible.
• Keep all drains free from choke.
• Top up all defective ground surfaces to prevent the accumulation of stagnant water.
• Stop storing water along morning walk trails or Government land for irrigation.
• Make large holes on tyres used as anti-bumping measure in garage or wrap them up with plastic cover to prevent water trapping or use mark(s) on the parking space to prevent bumping instead.
• Use mosquito screen to prevent the invasion of mosquito.
• Use insect repellents to provide temporary protection from mosquito bite.
• Use mosquito coils or aerosols to kill the mosquito directly.
