The Hawaii State Department of Health reported recent travel-related cases of Zika and dengue on Oʻahu, marking the first confirmed Zika case in 2026 and the 15th dengue case in 2025. Both cases were contracted abroad and are unrelated, with no evidence of local transmission, according to the Hawaii State Department of Health.
Zika can cause mild symptoms like fever, rash, and joint pain, but poses serious risks during pregnancy, while dengue can range from mild to severe. The Hawaii State Department of Health is conducting mosquito control and community outreach, and travelers are advised to prevent bites and take precautions against sexual transmission of Zika.
Travelers to tropical and subtropical regions should monitor for symptoms and seek medical care if needed. To prevent dengue and Zika, residents should remove standing water around homes. Suspected cases can be reported through the Hawaii State Department of Health Disease Reporting Line. More information is available on the DOH Disease Outbreak Control Division and Vector Control Branch websites.
