Niue had no dengue reported in 2025 or 2026. Pack repellent for the sea tracks anyway.
- No CDC travel notice for mosquito-borne disease
The World Health Organization's Pacific charts show zero dengue-like illness on Niue in every week of 2025 and of 2026 so far, while Tonga, Samoa and the Cook Islands declared outbreaks. There is no malaria. Day-biting mosquitoes are still around, so repellent before the walk down to Matapa Chasm or the Limu Pools covers it.
Are there mosquitoes in Niue? Yes, including the day-biting Aedes mosquitoes that can spread dengue, which the CDC lists for the island. Dengue has broken out in the past, though the World Health Organization's Pacific surveillance shows no dengue-like illness on Niue in 2025 or so far in 2026. There is no malaria, so the routine is light, with repellent before the sea tracks and after a swim.
Quiet while the neighbors had outbreaks
The World Health Organization's Western Pacific office counted Tonga, Samoa and the Cook Islands among the Pacific countries that declared dengue outbreaks in 2025, and Niue wasn't on that list. WHO's week-by-week tracking of dengue-like illness shows zero reports from Niue in every week of 2025 and of 2026 through early October. There is no CDC travel notice, and Niue isn't on CDC's global dengue list.
CDC's Zika page lists Niue among places with the mosquito that spreads Zika but no reported cases, and for those places it tells pregnant travelers to "Prevent mosquito bites during and after travel." The CDC recommends no malaria medicine or yellow fever vaccine for travelers from the US, and Niue requires proof of yellow fever vaccination only from travelers 9 months or older arriving from a country with yellow fever risk.
The sea tracks and the reef pools
Niue has a reputation for fewer mosquitoes than you might expect, often credited to the raised coral island having no streams or swamps, though some visitors advise strong repellent. Day-biting mosquitoes tend to wait in shade, so the forested sea tracks that drop to Matapa Chasm, the Limu Pools, Togo Chasm and the Talava Arches are the likeliest places for bites. Put repellent on over sunscreen before the walk down, reapply after swimming, and choose a room with screens or a bed net. Flies tend to be the other daytime nuisance.
When to go
May to October, the drier stretch and the main visitor season, tends to be the easier half of the year, and the November–April wet and cyclone season tends to bring more mosquitoes. The virus can arrive with travelers, so whatever the month, check whether Tonga, Samoa or the Cook Islands has an active outbreak before you fly, and be extra careful with repellent if one does.
Where you're going
Alofi
The small capital with the wharf, shops and most guesthouses. No dengue was reported in 2025 or so far in 2026, so a morning coat of repellent and a screened room cover a stay.
The sea tracks: Matapa, Limu, Togo & Talava
Steep paths through coastal forest to swimming chasms and reef pools, where the shade tends to hold daytime mosquitoes. Put repellent on before the walk down and reapply after swimming.

The Niue kit
- Picaridin 20% travel sprays: odorless, layers over sunscreen and quick to reapply after a swim in the Limu Pools. One 3.4 oz bottle covers about a week of daily use for one person.
- Oil of lemon eucalyptus 30%: the EPA-registered plant-based option, if you prefer one. Not for children under 3.
One rule outlasts the trip. Any fever during or after your trip means a doctor visit, and you tell them you were in Niue and where else you traveled in the Pacific.
Traveler questions
Is there dengue in Niue?
None has been reported recently. The World Health Organization's Pacific surveillance shows zero dengue-like illness on Niue in 2025 and in 2026 through early October, even while Tonga, Samoa and the Cook Islands had declared outbreaks in 2025. Dengue has broken out on Niue in the past, and the CDC lists it, so a daytime repellent habit still makes sense.
Do I need malaria pills or a yellow fever vaccine for Niue?
No. The CDC lists no malaria for Niue and recommends no malaria medicine. The yellow fever vaccine isn't recommended, and you don't need proof of it when you fly in from the US.
Are there mosquitoes at Matapa Chasm and the Limu Pools?
Likely a few. The sea tracks run through shaded coastal forest, which is where daytime mosquitoes tend to wait. Put repellent on over sunscreen before the walk down, and reapply after swimming, since a dip in the chasm or the pools washes some of it off.
