After the outbreak of Corona Virus Disease 2019 (COVID-19), relevant enterprises and institutions have adopted the "emergency braking " method for epidemic prevention and control, which played a positive role in the control of the epidemic. At present, enterprises and construction sites across the country have returned to work and production in an orderly manner. Under the unified leadership of the Chinese government, medical and health institutions have actively assisted in the prevention and control of the epidemic in construction site and enterprises, ensuring that both the epidemic prevention and economic activities are not delayed. This article summarizes the epidemiological knowledge of the novel coronavirus and COVID-19 based on the literature, national laws, regulations, and regulatory documents. At the same time, we propose hygiene measures and employee self-health management recommendations applicable to construction site and enterprises to provide reference for general practitioners and prevention and control personnel.
