People in Wallis and Futuna are being advised to take precautions against the spread of dengue after three cases were confirmed in the south of Wallis.
The newspaper, Nouvelles Caledoniennes, said several dozen suspected cases had been reported earlier in the week.
Travellers to the French territory are advised to apply insect repellants, and should they get a fever to contact a doctor.
Those flying out to New Caledonia have been given brochures warning them that any outbreak of a fever should be checked to determine whether it's dengue.
The same campaign softened the impact of earlier dengue outbreaks in New Caledonia and French Polynesia.
