French Guiana (FG), a French overseas territory in South America, is susceptible to tropical diseases, including arboviruses. The tropical climate supports the proliferation and establishment of vectors, making it difficult to control transmission. In the last ten years, FG has experienced large outbreaks of imported arboviruses such as and , as well as endemic arboviruses such as dengue, , and virus. Epidemiological surveillance is challenging due to the differing distributions and behaviors of vectors. This article aims to summarize the current knowledge of these arboviruses in FG and discuss the challenges of arbovirus emergence and reemergence. Effective control measures are hampered by the nonspecific clinical presentation of these diseases, as well as the mosquito's resistance to insecticides. Despite the high seroprevalence of certain viruses, the possibility of new epidemics cannot be ruled out. Therefore, active epidemiological surveillance is needed to identify potential outbreaks, and an adequate sentinel surveillance system and broad virological diagnostic panel are being developed in FG to improve disease management.
法属圭亚那（FG）是南美洲的一个法国海外领地，容易受到热带疾病的影响，包括虫媒病毒。热带气候有利于媒介的繁殖和传播，使得传播难以控制。在过去十年中，FG 经历了大规模的输入性虫媒病毒爆发，如 和 ，以及地方性虫媒病毒如登革热、 和 病毒。由于媒介的分布和行为不同，流行病学监测具有挑战性。本文旨在总结 FG 中这些虫媒病毒的现有知识，并讨论虫媒病毒的出现和再次出现的挑战。这些疾病的非特异性临床表现以及 蚊子对杀虫剂的耐药性，阻碍了有效控制措施的实施。尽管某些病毒的血清阳性率很高，但仍不能排除新的疫情爆发的可能性。因此，需要进行积极的流行病学监测，以识别潜在的疫情爆发，并在 FG 建立了适当的哨点监测系统和广泛的病毒学诊断面板，以改善疾病管理。
