Is it possible to prevent dengue fever? Is there a dengue fever vaccine?

The transmission of the virus to mosquitoes must be interrupted to prevent the illness. To this end, patients are kept under mosquito netting until the second bout of fever is over and they are no longer able to transmit the virus to a biting mosquito.

The prevention of dengue fever requires control or eradication of the mosquitoes carrying the virus that causes dengue. In nations plagued by dengue fever, people are urged to empty stagnant water from old tires, trash cans, and flower pots. Governmental initiatives to decrease mosquitoes also help to keep the disease in check but have been poorly effective.

To prevent mosquito bites, wear long pants and long sleeves. For personal protection, use mosquito repellant sprays that contain DEET when visiting places where dengue is endemic. There are no specific risk factors for contracting dengue fever, except living in or traveling to an area where the mosquitoes and virus are endemic. Limiting exposure to mosquitoes by avoiding standing water and staying indoors for two hours after sunrise and before sunset will help, as the Aedes aegypti mosquito is a daytime biter with peak periods of biting around sunrise and sunset. It may bite at any time of the day and is often hidden inside homes or other dwellings, especially in urban areas.

The first vaccine for dengue fever, Dengvaxia, became available in December 2015 and is approved for use in Mexico, the Philippines, and Brazil. It is only approved for use in people 9-45 years of age who live in dengue-endemic areas. In clinical trials, Dengvaxia reduced the chances of developing dengue by about 60%.

Five other vaccines for dengue are undergoing clinical trials, but none have yet been approved for use.

Where can people get more information on dengue fever?
