CDC Issues Fiji Dengue Alert: 800+ Weekly Cases Spike Triples Normal Rate, Travelers Warned to Take Precautions

Fiji now faces a serious dengue fever outbreak. The U.S. Centers for Disease Control and Prevention has placed the popular island destination under a Level 1 travel notice. This lowest-level advisory tells visitors to “practice usual precautions” rather than avoid travel altogether.

The numbers show why health officials worry. Fiji recorded over 2,400 dengue cases between January and late February 2025. Weekly cases topped 800 by early April. These figures far exceed the normal rate for this time of year.

Heavy rainfall created perfect breeding conditions for the Aedes mosquito that spreads dengue. The current outbreak features two main virus types – DENV-2 and DENV-3.

Fiji’s health ministry declared the outbreak in February. They urged residents and visitors to protect themselves and seek medical help quickly if symptoms appear.
