对新型冠状病毒肺炎流行病学调查的几点思考

Some thoughts of epidemiological investigation on Corona Virus Disease 2019

流行病学调查多用于常见疾病病因探讨和疾病特征分布描述,在此次新型冠状病毒肺炎(简称新冠肺炎)疫情传染源溯源和密切接触者判定过程中也发挥着重要作用。笔者在对新冠肺炎病例的流调过程中发现,受流调人员本身、被流调对象和公众对流调工作认知度等因素影响,个别病例的流调质量不高,病例溯源和密切接触者判定工作受阻,直接影响疫情防控效果。笔者提出在今后工作中通过采取加强流调人员队伍建设、改进流调手段、开展公众普法宣传、及时进行经验总结等措施提高对新发和再发传染病的流调质量,进而及时有效处置各类疫情。
