Newly emerged SARS-CoV-2 virus has been identified in China since 2019 and is still progressing as a tense threat to the human health worldwide. This virus can cause an acute respiratory infection in its host and terminate to death in more acute circumstances. To distinguish the environmental factors affecting the prevalence of this disease and to constitute an appropriate health strategy, databases were reviewed. Coronavirus is mainly transmitted person to person through respiratory droplets, but the disease could also be spread through secondary routes such as air, close contact and contaminated surfaces. The transmission of coronavirus through food has not been conclusively proven, but there are concerns about the food preparation, storage, infected staff and proper use of personal protective equipment. The possible transmission are through contaminated water and sewage, especially in the areas where patients have symptoms such as diarrhea and vomiting. In this study, we describe the essential strategies needed to prevent the spread of Covid-19 disease. Based on the most important criteria, this study developes a prevention model and health strategy that includes training and updating information, improvement programs, risk assessment and environmental monitoring, operational measures as well as supportive approaches and programs, which can be used step by step to reach a healthy environment, increase compliance with protocols and decrease the incidence of Covid-19.
