2022年臺中市潭子區本土登革熱社區群聚事件

Dengue Fever Cluster in Tanzi District, Taichung City, 2022

2022年8月18日中部某醫院通報1例臺中市潭子區55歲男性確定為本土登革熱個案。經衛生單位擴大疫調及篩檢，迅速發現另3例個案，其中2例研判為境外移入個案。本群聚共計有2名本土登革熱確定病例，為臺中市近3年來首度爆發本土登革熱群聚事件。經疫情調查發現該2例境外移入個案於返臺前即有身體不適症狀，居住社區附近有多個陽性孳生源及白線斑蚊成蚊，推測本案可能因境外移入感染者引發本次疫情。經衛生單位極力執行各項防治措施，包括疫情調查、跨局處動員、醫療院所訪視及衛教宣導等，在中央與地方充分協調合作之下，使疫情獲得控制。

On August 18, 2022, one hospital in central Taiwan reported a dengue fever case of a 55-year-old man residing in Tanzi District, Taichung City. After an expanded epidemiologic investigation conducted by the local health unit, three additional cases, including one domestic case and two imported cases, were discovered.
The two imported cases showed typical dengue symptoms during their international trip before returning to Taiwan. Multiple positive mosquito breeding site and adult Aedes albopictus mosquitoes were found in the neighborhood.
We speculated that two domestic cases might have contracted dengue fever related to imported cases, causing this outbreak.
This is the first locally-acquired dengue fever cluster in Taichung City in three years. The local health units implemented various prevention approaches and control measures, including epidemiologic investigation, collaborations among agencies, medical institution visits, health education propaganda. With all the efforts from the central and local governments, the epidemic was swiftly controlled.
