The objective of this study was to investigate the impact of physical distancing measures on the transmission of COVID-19. A scoping review was conducted, with a focus on English-language literature available on Pub Med and Web of Science up to May 2022. The findings of this study indicate a statistically significant correlation between physical distance and the transmission of COVID-19. Nevertheless, it should be noted that COVID-19 primarily spreads through contact routes and respiratory droplets, and many aspects of its transmissibility are still not fully understood. As such, the topic of airborne transmission of COVID-19 remains a subject of debate and controversy.</span></span></span></span></span></span></div> Physical distance, COVID-19, MERS, SARS, Transmission, 113 120 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-594-1&slc_lang=en&sid=1 Abdolkazem Neisi akneisi@ajums.ac.ir 100319475328460013388 0000000158605908 No Air Pollution and Respiratory Diseases Research Center, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran; Department of Environmental Health Engineering, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.
