Dengue is a mosquito-borne viral infection mainly caused by the bite of an infected female Aedes mosquito. The virus responsible for the disease is called dengue virus (DENV), which has four serotypes. It is transmitted to humans through the bites of infected female mosquitoes, primarily the Aedes aegypti mosquito. Most dengue cases occur in tropical areas of the world, including the Indian subcontinent, Southeast Asia, Southern China, Taiwan and The Pacific Islands.

Tips to stay guarded this monsoon

Dengue is more common during the monsoon season. The best way to prevent dengue is to take precautions to avoid being bitten by mosquitoes. Following the tips below may help reduce your risk of mosquito bites:

Mosquitoes breed in stagnant water. So, eliminate sources of stagnant water around you. Turn over tin cans, buckets, old tires, empty flowerpots and other artificial containers so that they do not collect water.
Keep the buckets and drums that are used for storing water covered.
Change the water in pet bowls, bird baths, rain barrels and plant containers at least once a week.
Discard the plants that you keep in water at home.
Avoid being outside during dawn and dusk, as many species of mosquitoes are most active during this time. Also keep windows and doors closed during these hours.
Wear long-sleeved shirt, long pants and closed-toe shoes, if possible, to limit exposed skin.
Apply mosquito repellents whenever possible or wear mosquito patches.
Clean your cooler regularly.
Keep the dustbins clean to avoid mosquitoes breeding on it.
Use a mosquito net while sleeping.
Adult mosquitoes tend to lurk in dark areas such as closets, behind curtains, under beds. Keep toddlers and infants away from such areas.
Ensure proper lighting in your home.
