Risk factorsBy Mayo Clinic staff
Factors that put you at greater risk of developing dengue fever or a more severe form of the disease include:
- Living or traveling in tropical areas. Being in tropical and subtropical areas around the world — especially in high-risk areas, such as Southeast Asia, Latin America and the Caribbean — increases your risk of exposure to the virus that causes dengue fever.
- Prior infection with a dengue fever virus. Previous infection with a dengue fever virus increases your risk of having severe symptoms if you're infected a second time. This is especially true for children.
