Hawaiʻi reports sixth dengue case of 2026 after travel-related Oʻahu infection

The Hawaiʻi Department of Health reported a new travel-related dengue virus case on Oʻahu on July 10, bringing the statewide total for 2026 to six cases.

The affected individual was exposed while traveling in a region where dengue is common, according to the department. The announcement identifies the case as travel-related; it does not state that mosquito-borne transmission occurred locally in Honolulu or elsewhere on Oʻahu.

State health officials said they deployed response teams to assess the situation and conduct mosquito-control and public-health activities. The department’s announcement is a surveillance update and does not describe the case as an outbreak.

What health officials are asking people to do

The Department of Health said clinicians and people who suspect dengue should contact the state Disease Reporting Line at 808-586-4586. The department also continued prevention messaging focused on avoiding mosquito bites.

The guidance is directed both at health-care professionals who may encounter a suspected case and at people who believe they may have dengue. The announcement does not provide eligibility criteria for testing, treatment instructions or a public deadline for taking action.

Residents and visitors can use the update as a reminder that travel-associated dengue remains a public-health concern in Hawaiʻi. The newly reported case involved exposure outside the state, and the statewide count reflects dengue cases reported during 2026 after the July 10 announcement.

What is known about the case

The department did not identify the patient or disclose the specific travel destination. It also did not provide demographic details, a case timeline beyond the July 10 announcement, or further details about the mosquito-control and public-health work being conducted.

Those limits are important when interpreting the report. The confirmed information is that health officials identified a travel-related case on Oʻahu and that the state’s 2026 total reached six. The release does not establish that the illness was acquired in Hawaiʻi, nor does it report local mosquito-borne spread.

The Hawaiʻi Department of Health’s Disease Outbreak Control Division is the state contact point named in the reporting guidance. The department published the update in its July 10 news release and listed it in its 2026 news-release archive.
