摘要
目的 了解四川省2019年登革热流行特征,为当地登革热的防控提供科学依据。方法 收集四川省2019年登革热监测资料,采用描述性流行病学方法分析流行特征。结果 共报告登革热病例350例,其中本地病例19例(5.43%)。全年均有病例发生,6~10月为发病高峰(73.71%),其中本地病例发病时间是8~10月。病例主要分布在成都、广安、眉山、南充等市(58.57%);发病年龄均值为36.35岁,主要集中在25~49岁(67.71%);男女性别比为2.43∶1;职业以农民、民工和工人人群的发病数最多(44.57%)。境外输入地主要集中在东南亚(柬埔寨60.12%),境内输入地为云南、重庆、广东三省(9.06%)。本地病例地区分布为泸州市18例(均为登革Ⅰ型病毒)、广安市1例。结论 在夏秋季应加强对重点地区重点人群的监测和健康教育,应提高临床医生对登革热本地病例的诊断水平,从而提高监测系统的敏感性。
