The WHO’s Western Pacific Region continues to face a high burden of mosquito-borne arboviral diseases in 2025, particularly dengue fever.
The Dengue Situation Update #726 states that dengue has become endemic in various Member States, which are favorite vacation destinations.
For example, Fiji’s Ministry of Health and Medical Services has reported 10,969 cases of dengue nationally. Eight deaths have been confirmed as directly attributed to the dengue outbreak, which has been driven predominantly by DENV-2.
According to local media reporting on August 4, 2025, Health Minister Dr Ratu Atonio Lalabalavu stated, “Ongoing awareness has been constantly done throughout, mainly in the Western Division and in the Northern Division.”
To alert international travelers, the U.S. CDC lists various countries reporting dengue outbreaks in 2025.
From a prevention perspective, in addition to avoiding mosquito bites, various countries in the Pacific Region offer the second-generation dengue vaccine. This vaccine is unavailable in the United States.
