部分地。这指的是登革热，一种由蚊子传播的病毒。CDC 数据显示，美国病例在 2024 年急剧上升（报告 3,798 例，约为 2010-2023 年平均水平的 ~359%），但 97% 与旅行相关。严重病例可能涉及出血和器官衰竭（包括大脑），尽管大多数病例较轻。CDC 为 12 个国家的疫情发布了 1 级旅行警报。蚊虫防护是主要防御措施。

Partially. This refers to dengue fever, a mosquito-borne virus. CDC data shows US cases rose sharply in 2024 (3,798 reported, ~359% above the 2010-2023 average), but 97% were travel-related. Severe cases can involve bleeding and organ failure (including brain), though most are milder. CDC issued Level 1 travel alerts for outbreaks in 12 countries. Mosquito protection is the main defense.
