French overseas territory Guadeloupe declares dengue epidemic

The tiger mosquito transmits the dengue fever virus.

The Caribbean archipelago of Guadeloupe has declared a dengue epidemic, with authorities noting the outbreak was being driven by a less common strain of the mosquito-borne disease.

"Dengue fever has entered the epidemic phase," the mayors' association and regional health authorities said in a statement on Thursday night.

It stated that a strain of the dengue virus that has not circulated much in the last 20 years had led the authorities to fear the possibility of "severe forms" with "a high number of cases to be expected if control and prevention actions are not implemented".

The dengue 3 serotype (DENV-3) is one of four variants of the virus.

The health authorities said among 62 samples analysed between late September and mid-October, 97 percent were caused by DENV-3.

The average of 80 cases per week at this time of year has been far surpassed.

At the end of October the agency estimated the weekly figure hit 540 – more than double the number seen in September.

Hospitals were reporting a similar spike, with around 40 emergency room visits per week for suspected dengue cases, compared with 25 in September.

Combat breeding grounds

The virus is spread by the Aedes "tiger" mosquito that breeds in stagnant pools.

It also advised people to wear loose-fitting clothing to cover the skin, use insect repellent and mosquito netting over beds.
