Countries: World, Australia, Cambodia, New Caledonia (France), New Zealand, United States of America, Vanuatu . Highlights/updates since the last map was sent on PacNet on 07 July 2026: Dengue • New Caledonia: As of 05 July 2026, a cumulative total of 2,181 dengue cases have been reported in New Cal
Key takeaway After peaking in week 17, the epidemic is now in a declining phase, consistent with the onset of the cool season, which is usually associated with a slowdown or interruption of transmission.
Why this matters
The dengue outbreaks in New Caledonia and Vanuatu highlight the ongoing challenges of epidemic management in the Pacific region. In New Caledonia, the decline in cases coincides with the onset of the cool season, but the high incidence rate among young people, particularly in school settings, suggests that targeted prevention and education efforts may be necessary to prevent future outbreaks. The presence of Wolbachia in mosquitoes in Grand Nouméa, where the World Mosquito Program is deployed, appears to have contributed to lower incidence rates in that area, demonstrating the potential effectiveness of such initiatives. In Vanuatu, the continued outbreak on South-West Efate Island underscores the need for sustained surveillance and response efforts. The fact that cases are concentrated in specific areas, such as the Pango Area Council, suggests that localized interventions may be effective in controlling the outbreak. Faith-based organizations and charities may play a critical role in supporting these efforts, particularly in remote or underserved areas where access to healthcare and education may be limited.
