Treatment for Dengue Fever

There is no specific medicine to treat dengue infection. If you think you may have dengue fever, you should use pain relievers with acetaminophen and avoid medicines with aspirin, which could worsen bleeding. You should also rest, drink plenty of fluids, and see your doctor. If you start to feel worse in the first 24 hours after your fever goes down, you should get to a hospital immediately to be checked for complications.

Preventing Dengue Fever

The best way to prevent the disease is to prevent bites by infected mosquitoes, particularly if you are living in or traveling to a tropical area. This involves protecting yourself and making efforts to keep the mosquito population down. In 2019, the FDA approved a vaccine called Dengvaxia to help prevent the disease from occurring in adolescents aged 9 to 16 who have already been infected by dengue. But, there currently is no vaccine to prevent the general population from contracting it.

To protect yourself:

  • Use mosquito repellents, even indoors.
  • When outdoors, wear long-sleeved shirts and long pants tucked into socks.
  • When indoors, use air conditioning if available.
  • Make sure window and door screens are secure and free of holes. If sleeping areas are not screened or air conditioned, use mosquito nets.
  • If you have symptoms of dengue, speak to your doctor.

To reduce the mosquito population, get rid of places where mosquitoes can breed. These include old tires, cans, or flower pots that collect rain. Regularly change the water in outdoor bird baths and pets’ water dishes.

Dengue Sri Lanka - Wolbachia
Dengue Fever Spreading in Sri Lanka Stats Figures Data

The NDCU plans to introduce bio-control measures to contain the spread of dengue by introducing a bacteria, which grows inside the body of the vector inhibiting the transmission of the disease. Wolbachia, the bacteria is to be introduced into the bodies of Aedes aegypti, identified as the main carrier of dengue virus in Sri Lanka. Known as an extremely common bacterium Wolbachia naturally occurs in 60 percent of insect species including some mosquitoes. However, Aedes aegypti and Aedes albopictus two mosquito species that carry the dengue virus don’t normally carry Wolbachia in their bodies.

Wolbachia, inside the body of the vector, competes with the virus for food and energy, making it hard for the virus to reproduce inside the mosquitoes, inhibiting the transmission of the virus. The bacterial is naturally passed on from one mosquito generation to another through eggs. Safe for humans and the environment the release of Wolabachia induced A. aegypti by the NDCU is scheduled to happen during the first two weeks of February.
