Modes of transmission of SARS-CoV-2 and evidence for preventive behavioral interventions
TLDR
The current literature suggests that SARS-CoV-2 is transmitted among the human population primarily through respiratory droplets and, to a lesser extent, via aerosols, and transmission appears to be affected by temperature, humidity, precipitation, air currents, pH, and radiation in the ambient environment.
