Dengue fever has returned to New Caledonia, with confirmed cases in the territory. During the rainy season, the presence of stagnant water promotes mosquito breeding and can accelerate transmission.

Since the beginning of the year through March 11, health officials have reported 236 cases, including 25 in just the last week.

205 of the cases are classified as confirmed locally-acquired, 27 as probable local transmission, 3 confirmed imported and 1 clinical case. DENV‑1 is the predominant serotype among locally acquired cases.

The mean age of cases is approximately 27 years, with a slight female predominance. Ten cases have required hospitalization. Most patients have since been discharged, with one patient remaining hospitalized.

A total of 23 municipalities have reported cases, with an overall incidence rate of 66 per 100,000 inhabitants. The highest incidence rates have been observed in Thio, Pouébo, Poya, Ouégoa, and Hienghène, indicating significant transmission in the northern and eastern parts of the territory.

Health authorities continue enhanced surveillance, vector control activities, and public health messaging, particularly during the current hot and rainy season, which is conducive to mosquito proliferation.

Dengue fever is a viral disease transmitted by mosquitoes ( Aedes aegypti ). It can cause high fever, headaches, extreme fatigue, muscle and joint pain, and sometimes nausea or a skin rash. In some cases, it can develop into a severe form: it is important to seek medical help quickly.

To limit the risk of dengue, everyone’s vigilance is essential : the goal is to reduce mosquitoes around your home and avoid bites.

3 simple steps to protect yourself

Empty containers after each rainfall : saucers, buckets, old tires… and remove any litter around the house.
No standing water = fewer mosquitoes.

Protect yourself from bites : use repellents (sprays, creams), wear long, light-colored clothing , and sleep under a mosquito net .

Consult a doctor at the slightest doubt : high fever, headache, muscle or joint pain, extreme fatigue.
