While current COVID-19 theory is such that the COVID-19 virus is transmitted via larger liquid droplets emitted when a person speaks, coughs or sneezes, the WHO indicates that research into the virus becoming a transmissible aerosol (e.g. transmitted through the particles floating in the air) is still inconclusive. While the research is finalized, it may be prudent to start using LEV as a capture and control solution. In other words, the absence of scientific certainty should not prevent a prudent response.
