HONOLULU, HI - March 22, 2026 - Hawaii's Department of Health today confirmed a new travel-related case of dengue fever on Oahu, elevating the total number of cases to 14 since the outbreak began in late October 2025. This latest development underscores the ongoing risk posed by imported cases and the importance of vigilance among both residents and visitors.

The newly confirmed case involves an individual who developed symptoms consistent with dengue fever after recent international travel. While officials have not disclosed the specific origin of the traveler's journey, the pattern of cases continues to point towards the introduction of the virus from endemic areas.

"The consistent link to international travel is a key indicator," stated Dr. Sarah Kemble, Hawaii's Health Director. "This emphasizes that while local transmission hasn't been established, the potential is ever-present with increased global travel. We are urging everyone who has recently returned from regions where dengue is common to be particularly aware of the symptoms and to seek medical attention if they experience any concerning signs."

Understanding Dengue Fever

Dengue fever is a mosquito-borne viral infection prevalent in tropical and subtropical regions globally. The virus is transmitted to humans through the bite of infected Aedes aegypti and, to a lesser extent, Aedes albopictus mosquitoes. Symptoms typically manifest within 4-10 days after the bite and can range from mild flu-like illness to severe, life-threatening complications.

Common symptoms include high fever, severe headache (often behind the eyes), joint and muscle pain (giving dengue the nickname "breakbone fever"), rash, nausea, and vomiting. In severe cases, dengue can develop into dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS), which can be fatal.

Currently, there is no specific antiviral treatment for dengue fever. Medical care focuses on managing symptoms, providing supportive care, such as hydration, and monitoring for complications.

Hawaii's Vulnerability and Response

While Hawaii is not naturally endemic for dengue fever, its tropical climate and the presence of Aedes aegypti mosquitoes create a favorable environment for potential outbreaks. The current situation highlights the state's vulnerability to imported cases and the importance of robust mosquito control programs.

The Hawaii Department of Health has been actively engaged in mosquito surveillance and control efforts, particularly in areas surrounding the confirmed cases. These efforts include larval source reduction (eliminating standing water where mosquitoes breed), targeted insecticide spraying, and public education campaigns.

"We're focusing our resources on preventing the establishment of local transmission," Dr. Kemble explained. "That means aggressively controlling mosquito populations and educating the public about personal protective measures."

Protecting Yourself and Others

Health officials strongly recommend the following precautions to protect against dengue fever:

• Use Insect Repellent: Apply insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus to exposed skin and clothing, following product instructions.
• Wear Protective Clothing: When outdoors, wear long-sleeved shirts and long pants to minimize skin exposure to mosquitoes.
• Eliminate Standing Water: Regularly inspect your property and eliminate standing water in containers such as flower pots, tires, buckets, and gutters. Mosquitoes can breed in even small amounts of water.
• Stay in Screened Areas: Use window and door screens to keep mosquitoes out of your home.
• Seek Medical Attention: If you experience symptoms of dengue fever, particularly after recent travel, see a doctor immediately.

Looking Ahead

The Hawaii Department of Health is continuing to monitor the situation closely and will provide updates as needed. Public health officials are also working with travel agencies and healthcare providers to raise awareness about the risks of dengue fever and to ensure prompt diagnosis and treatment of suspected cases. With spring and summer approaching, the risk of increased mosquito activity is expected. Residents and visitors are encouraged to stay informed and take proactive steps to protect themselves and prevent the spread of this potentially serious illness. Experts also suggest exploring the possibility of implementing pre-travel vaccination programs, if an effective dengue vaccine becomes widely available in the near future.
