Abstract

After detection of 2 clinical lymphatic filariasis (LF) cases in a postelimination context in 2023 on the island of Futuna (Wallis and Futuna archipelago), the Wallis and Futuna Health Agency conducted a LF prevalence survey in Futuna in May 2024. This cross-sectional study, carried out among schoolchildren <18 years of age, identified 5 children with antigenemia, indicating an estimated antigenemia prevalence in Futuna children nearing 2%. The study also confirmed a spatial cluster of cases in the village of Taoa, where the child antigenemia prevalence reached 7.5% (95% CI 2.1%–18.2%), and demonstrated a link between infection and traditional housing. We observed microfilariae in contact cases during secondary investigations. These findings suggest resurgence of LF in a postelimination context, in which the expected child antigenemia prevalence should not exceed 1%. This situation should prompt a new mass drug administration campaign using triple therapy and the reinforcement of epidemiologic and entomologic surveillance.

瓦利斯群岛和富图纳群岛卫生局于 2023 年在富图纳岛（瓦利斯群岛和富图纳群岛）发现 2 例临床淋巴丝虫病（LF）病例后，于 2024 年 5 月在富图纳岛开展了一次 LF 流行率调查。这项横断面研究在 18 岁学龄儿童中进行，发现 5 名儿童患有抗原血症，表明富图纳儿童的抗原血症流行率估计接近 2%。这项研究还证实了陶阿村的病例空间集群，那里的儿童抗原血症发病率达到 7.5%（95% CI 2.1%-18.2%），并证明了感染与传统住房之间的联系。在二次调查中，我们在接触病例中观察到了微丝蚴。这些研究结果表明，在消灭蚊虫后的环境中，长尾蝇再次出现，预计儿童抗原血症发病率不应超过 1%。这种情况应促使开展新的大规模用药运动，使用三联疗法，并加强流行病学和昆虫学监测。

期刊介绍： Emerging Infectious Diseases is a monthly open access journal published by the Centers for Disease Control and Prevention. The primary goal of this peer-reviewed journal is to advance the global recognition of both new and reemerging infectious diseases, while also enhancing our understanding of the underlying factors that contribute to disease emergence, prevention, and elimination. Targeted towards professionals in the field of infectious diseases and related sciences, the journal encourages diverse contributions from experts in academic research, industry, clinical practice, public health, as well as specialists in economics, social sciences, and other relevant disciplines. By fostering a collaborative approach, Emerging Infectious Diseases aims to facilitate interdisciplinary dialogue and address the multifaceted challenges posed by infectious diseases.
