Dengue Fever

Dengue is a mosquito-borne viral disease caused by the Dengue virus. In this case, dengue virus is transmitted by female mosquitoes – Aedes aegypti. These dengue mosquitos generally bite during the daytime and are found everywhere (Both inside and outside the house). These mosquitos are found to be at the peak of their activeness at dawn and dusk. The symptoms can develop only after 6 to 10 days after bitten by an infected mosquito.

Dengue fever is transmitted by mosquitos which carry a dengue virus, which has four varied serotypes thought of to infect human beings. The serotypes mentioned above denotes a set of microorganisms that are exceptionally closely associated. These microorganisms can only be distinguished due to them having somewhat dissimilar antigens (the alien unit that affects the body and making us produce antibodies) which prompt the body to create some dissimilar antibodies. Dengue cases are more common in subtropical and the tropical regions of our planet, including our country.

Signs and Symptoms of Dengue Fever

Symptoms of Dengue Fever

Dengue has an unexpected attack, viz. a sudden start and these symptoms could be an indicator of its onset.

  • Loss of appetite.
  • Diarrhea and vomiting.
  • Gum and nose bleedings.
  • Bleeding of gums and nose.
  • Severe joint and muscle pain
  • Fatigue, Nausea, and Vomiting.
  • A sudden drop in blood pressure.
  • Multiple rashes and wounds on the skin.
  • Pain behind the eyes coupled with extreme headaches.
  • The patient might feel week with high fever for 3-7 days.

Diagnosis of  Dengue Fever

The presence of the Dengue virus in the blood cells can be diagnosed by isolation of the virus, testing serum samples, and by other molecular methods. A patient with this syndrome is allowed to have a few blood tests to check the total count of red blood cells, blood platelets, and other physical examinations are conducted by the physician to evaluate that the symptoms are caused by a dengue infection.

Treatment for Dengue Fever 

Treatment for Dengue Fever 

Till today, there is no definite treatments or specific medicine to treat dengue infection. In general, the doctor may generally recommend regulating the pain and fever by using paracetamol instead of aspirin(as it might stimulate bleeding) and increasing fluid ingestion. Children below the age of 12 should not be given aspirin until and unless specially prescribed by the doctor.

In severe cases, blood transfusions, intravenous (IV) fluid supplementation and 24 hours hospitalization are required.

Prevention of Dengue Fever

Prevention of Dengue Fever

The patient should take proper bed rest especially during the days when the fever is at its peak and take exclusion from work, school preschool or childcare.

People suffering from dengue must stay away from places where they could get bitten by mosquitoes and should stay at home till they are no longer infectious (around 3-5 days).

For avoiding this illness, make sure your surroundings are free of any water logging issues as the Aedes mosquito prefers to breed in stagnant clean water that could be found easily nearby our habitats.

Until now, no vaccine has been developed to prevent Dengue virus. The only prevention is to avoid mosquito bites.

  1.  Cover your skin by wearing long pants, and long-sleeved shirts.
  2. Use of mosquito repellents, traps, and nets.
  3. Keep all the doors and windows closed especially at dawn, dusk, and early evening to avoid the entry of Dengue mosquitoes.
  4. Keep your surrounding clean by removing all the wastes and cleaning the standing water.
