The coronavirus disease 2019 (Covid-19) became a global health concern and dramatically affected many aspects of life on earth. The effects of COVID-19 and its preventive strategies during 2019-2020 have been studied in the fields of psychology, sociology, economy, and politics (1-4). Although the world health organization and regional health authorities responded promptly to the pandemic, but most of the recommendations especially in the prevention and treatment of the disease were based on animal studies and studies conducted on other coronavirus diseases or influenza (5).
