In 2023, dengue virus serotype 2 (DENV2) affected most French overseas territories. In the French Caribbean Islands, viral circulation continues with > 30,000 suspected infections by March 2024. Genome sequence analysis reveals that the epidemic lineage in the French Caribbean islands has also become established in French Guiana but not Réunion. It has moreover seeded autochthonous circulation events in mainland France. To guide prevention of further inter-territorial spread and DENV introduction in non-endemic settings, continued molecular surveillance and mosquito control are essential.
2023 年,登革热病毒血清型 2(DENV2)影响了大多数法国海外领土。在法属加勒比地区,病毒仍在传播,截至 2024 年 3 月,疑似感染人数超过 3 万。基因组序列分析显示,法国加勒比岛屿的流行谱系也已在法属圭亚那立足,但未在留尼汪立足。它还在法国本土引发了本地传播事件。为了指导进一步的跨地区传播和非流行地区的登革热病毒输入的预防,持续的分子监测和蚊虫控制至关重要。
