Ten scientific reasons in support of airborne transmission of SARS-CoV-2

Ten scientific reasons in support of airborne transmission of SARS-CoV-2.

Heneghan and colleagues' systematic review, funded by WHO, published in March, 2021, as a preprint, states: “The lack of recoverable viral culture samples of SARS-CoV-2 prevents firm conclusions to be drawn about airborne transmission”. This conclusion, and the wide circulation of the review's findings, is concerning because of the public health implications. If an infectious virus spreads predominantly through large respiratory droplets that fall quickly, the key control measures are reducing direct contact, cleaning surfaces, physical barriers, physical distancing, use of masks within droplet distance, respiratory hygiene, and wearing high-grade protection only for so-called aerosol-generating health-care procedures.
