Detection of potential transmission foci of lymphatic filariasis using molecular xenomonitoring in Huahine, French Polynesia.

ABSTRACT:

Background

In French Polynesia, substantial progress has been achieved in eliminating lymphatic filariasis (LF) caused by Wuchereria bancrofti var. pacifica, a parasite transmitted by the mosquito vector Aedes polynesiensis. However, despite multiple rounds of Mass Drug Administration (MDA), LF transmission persists on some islands, underscoring the need for robust surveillance to evaluate transmission risks and identify potential transmission foci.

Methodology/principal findings

An extensive entomological survey combined with a Molecular Xenomonitoring (MX) study was conducted on Huahine Island in the Leeward Islands (Society Islands), where new LF cases continue to be reported. Adult mosquitoes were collected from 420 sampling points across 28 Primary Sampling Units (PSUs)
