Preventive Measures that Reduce your Risk of Dengue infection

By Dr. Latha

Dengue infection does not have any vaccination till date nor are there any definitive treatments for this infection. The only way we can overcome dengue is by preventing it from happening. This means avoiding mosquitoes from biting us. Mosquitoes lay the eggs and breed where there is stagnant water even a small quantity, for instance, containers to hold water at home or outdoors. This will include water kept for pets to drink, water in flower pots, decorative containers, and stockpiling barrels to store water. Search for stagnant water inside your home, for example, in vases with new blooms and clean it once a week. Female mosquitoes that carry dengue viruses are most active from dawn to dusk, but they can also bite at night hours.

 Apply mosquito repellent on your skin while inside or outside the house. Whenever possible, wear long sleeves covering the hand as much as possible and jeans to cover up the legs. Likewise, windows and entryway should be fitted with mesh screens so that only air can enter, keeping mosquitos away. Use of air conditioning is also a good option by closing all the windows and doors. Using mosquito nets while sleeping will avoid mosquitos from reaching you. Care should be taken to make sure that there is no way for mosquitos to reach you by tucking the net with no openings. Mosquito swatter bats are available in the market to vanquish mosquitos. These swatter bats can be electrically charged, and they can be used to kill mosquitos.

Avoid traveling to mosquito-infested areas, if it is unavoidable, then wear a long-sleeved shirt, long pants, socks, and shoes. Many people have a habit of storing unused items like vehicle tires, small containers or any item in open air. These items can collect rain water and even small quantities of water is enough to breed mosquitoes. So, avoid storing these items in the open air and dispose away items whenever they are not required.

Themiphos, Fenthion, or kerosene are commonly used chemical larvicidal agents. Biological larvicides like fish are also commonly used. Usually, Gambusia or guppy fishes are used as biological larvicides.The stagnant water should be drained. If you still find water stagnation on ground level around and find no way to remove them, chemical or biological larvicides can be sprayed on them to avoid mosquitos laying eggs on them or eggs breeding.

Unused wells and tanks have to be treated with biological larvicides or can be closed or destroyed. Engineers can help control dengue by preventing logging of water by designing buildings with sloping surfaces to avoid water clogging and building meshes to avoid mosquitoes entering the building.
