There were 4,717 laboratory-confirmed cases of dengue fever in 2025, and seven dengue-related deaths.

As of 4 January 2026, the Ministry of Health has recorded a cumulative total of 16,299 clinically diagnosed dengue cases since January 2025.

The figures showed that children under 15 years accounted for 74 per cent of the cases, and the circulating serotypes remain predominantly DENV-1 (91 per cent) and DENV-2 (9 per cent).

The figures showed that Case numbers increased by eight per cent % compared to the previous EpiWeek, with 40 new clinical cases, of which 19 are lab-confirmed.

There were no hospital admissions for this EpiWeek 01 (29 December–4 January 2026). The Ministry of Health continues its control measures combined with targeted sensitisation of the community and government leaders, and ongoing district and multimedia awareness, integrating dengue and measles messaging.

A MOH-UNICEF KAP survey shows improved dengue knowledge and risk perception, creating opportunities to promote protective behaviours.

The public is recommended to promote environmental clean‑ups to reduce mosquito breeding, use protective clothing, nets and repellents to prevent bites, and if illness occurs, to promptly seek medical care while monitoring household members for symptoms and testing.

Meanwhile, in New Zealand, the surveillance week 02 2026 (10 – 16 January 2026) showed there were 20 confirmed imported cases of dengue reported with travel history to the Cook Islands, one confirmed imported case of dengue with travel history to Samoa, and one confirmed imported case of Zika with travel history to Papua New Guinea.
