Dengue is a fever which spreads by the bite of Aedes aegypti mosquito infected with a dengue virus. This fever does not spread directly from a person to another, but only through a dengue infected mosquito. This mosquito bites during daylight hours. For the past ten years, the number of dengue cases has gradually increased in India.

What are the Risk Factors of Dengue Fever?


Here are some risk factors which can put you at risk of dengue fever:


  • Living in or traveling to tropical areas where dengue is endemic, which increases your exposure to the virus that causes the fever.

  • Supportive care in a hospital


  • IV fluid and electrolyte replacement


  • Transfusion to replace blood loss



How Can You Prevent Dengue Fever?



As of now, there is no vaccine to prevent dengue, so if children live in or visit areas where dengue fever is likely, the only way to protect them from the disease is to minimize their chances of being bitten by an infected Aedes mosquito.


Some general way to prevent dengue :


  • Use screens on doors and windows, and promptly repair broken or damaged screens. Keep unscreened doors and windows shut.


  • Wear long pants, long-sleeved shirts, shoes, and socks when you go outside, and also use mosquito netting over beds at night.


  • Use insect repellant for your child. Choose a repellant with DEET or oil of lemon eucalyptus.


  • Limit the time kids spend outside during a day, especially in the hours around dawn and dusk, when mosquitoes are most active.


  • Don’t give mosquitoes the space to breed. Mosquitoes lay their eggs in water, so get rid of standing water in things like containers and discarded tires, and be sure to change the water in birdbaths, dog bowls, and flower vases at least once a week.


  • By taking these precautions and staying away from areas that have a dengue fever epidemic, the risk of contracting dengue fever is small for international travelers.






In the end, do not ignore any symptoms of dengue fever and consult your doctor as soon as possible. He/She is the one who can help you to get relief from these symptoms.
