The Department of Public Health and Social Services is advising the community to take a proactive approach to preventing dengue virus infection, particularly in light of the recent dengue outbreak declared by the Quezon City Government in the Philippines. 

Although dengue is not endemic to Guam, it is common in tropical and subtropical areas of the world.

As part of its public health efforts, DPHSS monitors dengue cases in the ongoing U.S. outbreak, and across the Western Pacific Region, including multiple Pacific Island Country Territories. 

There have been zero identified dengue cases reported in Guam for 2024-2025.

Dengue is a viral disease spread through the bite of an infected mosquito. It is not spread directly from person-to-person. 

The most common symptoms associated with dengue is fever with any of the following:

  • Aches and pains (eye pain, typically behind the eye, muscle, joint, or bone pain)
  • Nausea or vomiting
  • Rash

Symptoms often begin within two weeks of being bitten by an infected mosquito and last about two to seven days. 

In some cases, dengue symptoms can worsen within hours.

The best way to prevent dengue is to avoid mosquito bites. Take precautions to prevent mosquito bites by applying insect repellant and wearing light-colored long-sleeved shirts and pants. 

Because mosquitos carrying dengue virus favor smaller areas of still water, individuals can assist in removing mosquito breeding sites by emptying or discarding items that can collect water. 

Individuals traveling to an area with risk of dengue are at risk for infection. 

Before traveling, travelers should find country-specific travel information (https://wwwnc.cdc.gov/travel/) to help plan and pack.

DPHSS encourages all residents to stay informed, take precautions, and seek medical care if needed.
