Dengue is a viral infection caused by dengue virus. This viral infection spreads by bite of aedes aegypti mosquito. Aedes aegypti is a daytime biting mosquito. It usually lives and breed in fresh water collections like: water coolers, broken pots, discarded tyres/tubes.
Dengue infection may cause fever, mild cough & cold and rashes on body. Child may also complain of frontal headache and eye pain. At times it may be associated with severe back pain, so also known as back-break fever. Most of the patients recover from dengue without any problem. But Children and females are more susceptible to develop complications like bleeding tendencies, liver involvement, breathing difficulty, shock (fall in blood pressure) and encephalopathy (involvement of brain).
Management of dengue includes adequate water intake, rest and medicines to control the fever and body pains. Few cases may need hospital admission, intravenous fluids and at times ICU care and blood products transfusion. As neither specific treatment of dengue is available nor the vaccine to prevent infection, so only thing what we can do is to prevent transmission of dengue form mosquito and other infected patients to healthy persons.
Prevention of Dengue
Prevention of mosquito bites:
By body covering clothes and use of mosquito nets we can protect ourselves from mosquito bites. Screen on windows and doorways are effective method for preventing mosquito entry into the houses.
Use of mosquito repellents, which are available in many form like bands, gels, creams, stickers etc
Destruction of breeding sites of mosquitoes. Proper disposal of rubber tyres, empty bottles and broken pots. Keep water containers covered. If water collection is unavoidable, pour oil over water collections, so that it make a thin layer of oil on water and so prevents egg laying and hatching.
Kill mosquitoes by regular ultra low volume spray of insecticides in community. Commercial sprays available can be used for in-house spray, but it usually temporarily paralyses mosquitoes, so sprayed mosquitoes shall also be squashed to prevent later recovery. Biological killing by putting larvicidal (larva eating) fishes in water collections and ponds can also be done.
Prevention of spread from dengue cases:
Isolate dengue patients to prevent fresh mosquito bites by uninfected mosquitoes. Mosquito net shall be used on patient’s bed and use mosquito coils to kill mosquitoes.
By taking above said precautions we can prevent dengue and so its complications and keep ourselves and kids safe.
