环境因素对新型冠状病毒肺炎传播影响的研究进展

Research progress on influence of environmental factors on transmission of coronavirus disease 2019

当前全球新型冠状病毒肺炎(COVID-19)疫情依然严峻,重点国家疫情未见缓和,欧洲、东亚等地区疫情均有不同程度回升,2020年7月23日全球累计确诊病例数超过1500万。我国部分地区疫情有所反弹,尤其国内外近期暴发多起聚集性感染事件,多份环境样本中检出SARS-CoV-2。环境因素在COVID-19传播中的作用引起了广泛关注。本文综述了多种环境因素影响COVID-19传播的研究进展,包括气象因素(大气温度、湿度和风速),污水和生活饮用水,空气,多种物体表面,食品、食品包装物和食品加工者以及昆虫媒介,强调环境卫生是防止疫情反弹和控制大规模传播的关键,并提出相应的预防控制建议。

The global pandemic of coronavirus disease 2019(COVID-19)remains challenging as it shows no signs of abating in key countries,but resurgence in European and East Asian regions.On July 23,the cumulative number of confirmed cases worldwide exceeded 15 million.The coronavirus pandemic has rebounded in some parts of China.In particular,there many outbreaks of cluster infections at home and abroad recently and SARS-CoV-2 have been detected positive in multiple environment samples.The role of environmental factors in the transmission of COVID-19 has attracted widespread attention.This article summarized the research progress of various environmental factors[such as meteorological factors(temperature,humidity,and wind speed),contaminated water and drinking water,air,surfaces,food,food packages,and food processors,and insects]affecting the transmission of COVID-19,emphasizing that environmental sanitation is one of the keys to controlling rebound and large-scale transmission of the pandemic,and proposed corresponding prevention and control recommendations.
