Many people are concerned about aerosol transmission of the new coronavirus, but aerosol transmission requires certain conditions to be met before it can occur. Aerosol transmission can only occur in extreme cases and requires three conditions to be met: confined space, prolonged exposure, and high levels of virus exposure. Aerosol transmission has limited conditions and does not occur under general conditions. In contrast, the chances of transmitting the new coronavirus through aerosols in an open environment are low. Therefore, personal protection can be observed and attention can be paid to the mode of transmission of New Coronavirus via aerosols, but there is no need for excessive worry and anxiety.
