The coronavirus 2019 pandemic, induced by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has strongly altered healthcare systems and the economy worldwide. The lack of knowledge on this virus has led to the implementation of uncertain strategies and measures to fight the pandemic. Here, we review environmental factors that control viral transmission, such as air, temperature, humidity, food, water and sewage, insects, inanimate surfaces, hand hygiene, and social distancing. The main route of viral transmission is the respiratory tract through aerosols. Masks and social distancing are effective in ceasing air transmission. Proper cleaning of surfaces and hand disinfection are required, especially in healthcare units. Food should be handled properly, and food handlers should work based on hygienic protocols. Water and sewage transmission, and transmission through insects appear less important than other environmental factors.

由严重急性呼吸系统综合症冠状病毒 2 (SARS-CoV-2) 引起的 2019 年冠状病毒大流行，极大地改变了全球医疗保健系统和经济。对这种病毒缺乏了解导致实施了不确定的战略和措施来抗击这一流行病。在这里，我们回顾了控制病毒传播的环境因素，例如空气、温度、湿度、食物、水和污水、昆虫、无生命的表面、手部卫生和社交距离。病毒传播的主要途径是通过气溶胶的呼吸道。口罩和保持社交距离可有效阻止空气传播。需要对表面进行适当的清洁和手部消毒，尤其是在医疗保健单位。食品应妥善处理，食品处理人员应根据卫生规程工作。
