聚集性疫情
聚集性疫情是指在一個特定的地理位置或時期內，出現異常和相對不常見的疾病疫情[1]。通常情況下，當流行病學家意識到可能出現聚集性疫情時，他們會向當地的公共衛生部門報告[2]。如果聚集性疫情規模進一步擴大，此種情況可能被重新認定為疾病爆發。

Aggregations of relatively uncommon events or diseases in space and/or time in amounts that are believed or perceived to be greater than could be expected by chance. Putative disease clusters are often perceived to exist on the basis of anecdotal evidence, and much effort may be expended by epidemiologists and biostatisticians in assessing whether a true cluster of disease exists.
