Sumario:WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Environmental factors such as temperature and humidity play important roles in the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) via droplets/aerosols. WHAT IS ADDED BY THIS REPORT? Higher relative humidity (61%–80%), longer spreading time (120 min), and greater dispersal distance (1 m) significantly reduced SARS-CoV-2 pseudovirus loads. There was an interaction effect between relative humidity and spreading time. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? The findings contribute to our understanding of the impact of environmental factors on the transmission of SARS-CoV-2 via airborne droplets/aerosols.
