Dengue virus

Dengue is caused by a virus and is transmitted by mosquitoes. It is an epidemic and is prevalent in rural and urban tropics. Consequences of dengue can sometimes be fatal. Dengue is characterized by severe joint and muscle pain, headache, swollen lymph nodes, fever, exhaustion, rashes and a complication known as dengue hemorrhagic fever, a dangerous combination of fever, pain, vomiting and bleeding.

There is no licensed vaccine available to treat or prevent dengue fever and efforts to develop one have been complicated due to the fact that dengue is caused by four distinct dengue viruses. Dengue can be prevented by eliminating breeding grounds for mosquito by means of good environmental hygiene practices.

Dengue symptom-headache

The signs and symptoms of the dengue infection usually begin after 4 to 8 days of being infected. The most common symptoms are high temperature, severe headache, pain behind the eyes, muscle and joint pain, nausea or vomiting and swollen glands.

Pain behind the eyes is also a common symptom. Some people can develop more severe symptoms and complications, such as with dengue hemorrhagic fever.


Dengue virus

Dengue is caused by one of the four dengue viruses and is transmitted by mosquitoes. Dengue is transmitted in a pattern. A mosquito bites an infected human, and then the infected mosquito bites another human. And so the cycle continues.

The risk of dengue increases due to poor water management, improper water storage and sanitation which act as breeding grounds for mosquitoes.


Dengue- treatment with fluids.

Currently there is no cure for dengue. There is no vaccine available to treat or prevent dengue fever. Efforts to develop a dengue vaccine have been complicated because of the fact that dengue is caused by four distinct dengue viruses.

Drinking fluids is one of the first line treatments recommended in an infected person, and if severe the person may require fluids intravenously. Medications to help reduce the fever and decrease the pain may be recommended by the doctor.


Dengue- mosquito repellent.

Since there are no medications to treat dengue, prevention against the dengue virus becomes even more important. There are several methods which can prevent the spread of dengue such as:

  1. Mosquito breeding control.
  2. Mosquito repellents.
  3. Increasing measures of hygiene like changing water in vases, cleaning of water storage containers etc.
  4. Wearing long full sleeved shirts to avoid mosquito bites.
