Dengue virus is transmitted by Aedea Mosquito. It bites during day time only. Outbreaks can occur at anytime, however rainy season with high humidity increases changes of transmission.

  • Itching

Most crucial Phase of Dengue illness occurs once fever subsides; i.e. at deffervescence of Fever as most of the complications arises at this time. At this time platelet counts start decreasing along with rise in Hematocrit values. 3rd space losing occurs, so it is very important to prevent dehydration and let your child have PLENTY OF FLUIDS.

Severe Cases (also called dengue hemorrhagic fever):

Special attention needs to be given to these warning signs as it could lead to severe dengue:

  • Severe abdominal pain
  • Persistent vomiting
  • Bleeding from any site eg gums, blood in vomiting etc
  • Rapid breathing
  • Fatigue/ restlessness
  • Altered sensorium

Treatment:

  • At present no vaccine is available.
  • No specific medication for dengue fever.
  • Mainstay of treatment is supportive
  • Patients should seek medical advice, rest and drink plenty of fluids.
  •  Paracetamol (Crocin) is the drug of choice for Fever. Other medications like aspirin or ibuprofen should be avoided as it increases the risk of bleeding.
  • Vital Monitoring along with blood test to have a look at Hematocrit along with platelet count.
  • Platelet transfusion in some cases

Infection with one strain will provide life-time protection only against that particular strain. However, it is still possible to become infected by other strains and develop into severe dengue. Usually re-infection cases are severe.

With proper medical care and early recognition, case-fatality rates are below 1%.

  • Indoor, Ant traps, Flower vases and saucers
  • Water storage tank (domestic drinking water, bathroom, etc…)
  • Plastic containers, Bottles, Outdoor, Discarded bottles and tins
  • Discarded tyres, Artificial containers, Tree holes, potholes, construction sites, Drums for collecting rainwater
  • Shells, husks, pods from trees, Leaf axils of various plants
  • Community participation is the key to dengue prevention. As every household aims to reduce vector density, the transmission rate will decrease or maybe even stop.
  • Protecting yourself from mosquito bites: It can be done by using
    • Long-sleeved clothing and mosquito repellents are the most viable options.
    • Window and door screens, air conditioning reduces the risk of mosquitoes coming into contact with the household members.
    • Mosquito nets (and/or insecticide-treated nets) will also provide additional protection to people sleeping during the day, or protect against other mosquitoes which can bite at night (such as malaria).
    • Household insecticides aerosols, mosquito coils or other insecticide vaporizers maybe also reduce biting activity.
