2001-2005年潍坊市风疹流行病学特征

Current Epidemiological Situation of Rubella in Weifang During 2001-2005

目的了解潍坊市风疹流行病学特征,为控制风疹提供科学依据。方法利用麻疹监测系统资料,包括流行病学和实验室监测及主动搜索等资料,分析潍坊市风疹流行病学特征。结果潍坊市2001-2005年报告风疹129例,年平均发病率3.04/10万,春季发病占80.62%,发病呈高度聚集状态,暴发病例占80.62%,9～17岁人群占75.97%。结论2001-2005年潍坊市风疹病例主要发生于暴发疫情,暴发全部来自学校,暴发病例绝大多数未接种过风疹疫苗或接种史不详,易感人群的大量积累,是造成风疹暴发的根本原因;今后应加强在校学生风疹疫苗的免疫接种,加强学校疫情监测,以减少风疹疫情。
