Population susceptible to type-4 strain

PAPEETE, Tahiti (Tahitipresse, July 2, 2009) – Health officials announced in Papeete that 1,760 dengue fever cases have been reported in French Polynesia over the last months.

All these cases have been confirmed by Tahitian laboratories since the beginning of the epidemic last February.

The type-4 dengue fever is now the only kind of dengue fever prevailing in French Polynesia.

Out of these 1,760 cases, only 29 were to sent to a hospital for a medical treatment.

The type-4 dengue fever mostly affects young persons. About 50% of the cases are persons aged between 10 and 19.

Health officials also stressed the fact that the dengue fever now affects the five archipelagoes of French Polynesia.

The type-4 dengue fever has not reached French Polynesia since the early 80's. This explains why so many inhabitants are susceptible to catching this dengue strain.

A dengue epidemic caused the death of 10 persons in French Polynesia in 2001.

There are four strains of dengue fever - 1, 2, 3 and 4. Historically, the 1 and 3 strains are the most frequently documented dengue epidemics since 1971 in French Polynesia.
