Dengue and Chikungunya in Our Backyard: Preventing Aedes Mosquito-Borne Disease

Tuesday, May 19 at 1pm EDT

Aedes albopictus mosquito

Aedes aegypti and Aedes albopictus mosquitoes are the primary vectors for dengue, chikungunya, yellow fever, and Zika viruses. Taken together, these viruses account for almost 100 million cases of mosquito-borne disease per year. Globally, dengue is the most important mosquito-borne viral disease. In the last 50 years, incidence has increased 30-fold by expanding into new countries and new areas. Chikungunya often occurs in large outbreaks with high infection rates, affecting more than a third of the population in areas where the virus is circulating. In 2014, more than a million cases were reported worldwide. While Chikungunya disease rarely results in death, the symptoms can be severe and disabling.

Outbreaks of mosquito-borne diseases depend on many factors and are especially difficult to predict, prevent and control. Because there are no licensed vaccines available to prevent dengue or chikungunya, controlling mosquito populations and reducing bites are currently the most effective prevention measures.

This session of Grand Rounds will highlight the importance of preventing Aedes mosquito-borne diseases and the need for improved diagnostic, prevention and control measures.


May 2015

Dr. Phoebe Thorpe and Dr. Marc Fischer discuss the diseases transmitted by Aedes aegypti mosquitos and some practical ways individuals can protect themselves.

Individuals should limit exposure to mosquitos by

  • Using repellants when outdoors
  • Emptying standing water sources around their homes
  • Wearing long pants and long-sleeves and
  • Ensuring that window and door screens are intact

Providers should

  • Take advantage of CDC’s clinical case management training
  • Be aware of signs and symptoms of mosquito-borne diseases
