Abstract: Objective To investigate the infestation of bed bugs in China, and to provide a scientific basis for the risk assessment of bed bugs. Methods The bed bug surveillance data were collected from the national vector surveillance system in China, 2019. The status of bed bug infestation was compared between different provinces or habitats. Results In 2019, bed bug surveillance was carried out in 11 provinces, autonomous regions, or centrally administered municipalities via field investigation and telephone survey. A total of 1 351 units were investigated on site, of which 10 had bed bug, with a positive infestation rate of 0.74%. A total of 13 589 standard rooms were investigated, of which 31 (0.23%) had bed bugs. A total of 212 professional organizations (pest control companies and Centers for Disease Control and Prevention) were investigated by telephone, of which 11 (5.19%) had dealt with/consulted about bed bugs. Conclusion Bed bugs are widely distributed in China. The dormitories of construction sites, factories and schools are the environments where bed bugs occur more frequently.

摘要： 目的 了解我国臭虫的发生情况，为臭虫发生的风险评估提供依据。方法 收集整理2019年我国病媒生物监测中臭虫监测数据，比较不同省份、不同环境类型中臭虫的发生情况。结果 2019年共11个省（自治区、直辖市）开展了臭虫现场监测和/或电话调查工作，现场共调查1 351个单位，有臭虫的单位10个，阳性率为0.74%；共调查13 589间房间（标准间），臭虫阳性房间31间，阳性率为0.23%；对212家专业机构（杀虫公司和疾病预防控制中心）进行电话调查，处理/咨询过臭虫的有11家，占调查总数的5.19%。结论 臭虫在我国分布十分广泛，工地宿舍、工厂宿舍、学校宿舍、旅馆是臭虫发生比较多的环境。
