About Dengue: What You Need to Know
- Dengue viruses are spread to people through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito. These mosquitoes also spread Zika, chikungunya, and other viruses.
- Dengue is common in more than 100 countries around the world.
- Forty percent of the world’s population, about 3 billion people, live in areas with a risk of dengue. Dengue is often a leading cause of illness in areas with risk.
- Each year, up to 400 million people get infected with dengue. Approximately 100 million people get sick from infection, and 22,000 die from severe dengue.
- Dengue is caused by one of any of four related viruses: Dengue virus 1, 2, 3, and 4. For this reason, a person can be infected with a dengue virus as many as four times in his or her lifetime.
Prevention: What is Know
- All four dengue viruses are spread primarily through the bite of an infected Aedes species (Ae. aegypti and Ae. albopictus) mosquito. These mosquitoes also spread chikungunya and Zika viruses.
- The mosquitoes that spread dengue are found in most tropical and subtropical regions of the world, including many parts of the United States.
- Ae. aegypti and Ae. albopictus bite during the day and night.
- A dengue vaccine is available for use in some parts of the world.

If You Have Dengue, Protect Others
- During the first week of infection, dengue virus is found in the blood of an infected person. If a mosquito bites the infected person, the mosquito becomes infected. The infected mosquito can spread the virus to other people through bites.
- Not everyone infected with dengue gets sick. Even if you do not feel sick, travelers returning to the United States from an area with risk of dengue should take steps to prevent mosquito bites for 3 weeks so they do not spread dengue to mosquitoes that could spread the virus to other people.
