What is sidestepped in public health advice is that “super-spread events” are clear-cut and can be prevented. In the absence of public health warnings, most people are simply unaware that opening windows can reduce or eliminate the virus spread in their homes and cars. Ventilation is key to prevention because the risk of breathing in Covid-19 is 20 times higher indoors. Public health advised avoiding the 3 Cs “closed spaces, crowded places, and close-contact settings”. Science-based rules, targeted public health advice, risk assessments and enforcement are critical now, not loose rules of thumb.
