How to prevent from Dengue Fever?

Dengue is spreading rampantly in Dharan. Dharan faced dengue epidemic in last year and previous year as well. However, the outbreak this year has posed more challenges. The Sunsari District Public Health Office has declared the sub-metropolis an outbreak-hit region.

Dengue, also called breakbone fever or dandy fever is a mosquito-borne viral infection. Besides fever, the disease is characterized by an extreme pain and stiffness of the joints. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a  lesser extent, Ae. albopictus.


Dengue viruses are spread to people through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito. The Aedes aegypti mosquito is the primary vector of dengue. The virus is transmitted to humans through the bite of infected female mosquitoes. Infected symptomatic or asymptomatic humans are the main carriers and multipliers of the virus, serving as a source of the virus for uninfected mosquitoes.

Signs and Symptoms

Symptoms usually begin 5 to 7 days after you are bitten by an infected mosquito. Symptoms usually last for 2–7 days. Dengue fever causes a high fever — 104 F degrees — and at least two of the following symptoms:

  • Headache

  • Muscle, bone and joint pain

  • Nausea

  • Vomiting

  • Pain behind the eyes

  • Swollen glands

  • Rash

Mild symptoms of dengue can be confused with other illnesses that cause fever, aches, and pains, or a rash. Most people recover within a week or so. In some cases, symptoms worsen and can become life-threatening. Blood vessels often become damaged and leaky. The platelets count decreases. This can cause a severe form of dengue fever, called dengue hemorrhagic fever, severe dengue or dengue shock syndrome.


  • There is no specific treatment for dengue/ severe dengue, but early detection and access to proper medical care lowers fatality rates below 1%.

  • Usually, analgesics, hydration and bed rest are enough to help patients through their infection.

  •  There is no specific medication to treat dengue.

Prevention of dengue fever

  • Wear long-sleeve shirts and long pants.

  • Treat clothes with repellents like permeth.

  • Use a mosquito net.

  •  Make sure windows and doors screens are closed to avoid allowing mosquitoes into inclosed space.

  • Avoid areas with standing water. Especially at times of high mosquito activity like dawn and dusk.

  • Stay in well-screened housing as the mosquitoes who carry dengue viruses are most active from dawn to dusk, but they can also bite at night.
