Coronavirus transmission: SARS-CoV-2 in the air

When the Covid-19 pandemic first began, most people focused on the risk of catching the new coronavirus from touching surfaces. Fast-forward to today, and it’s clear that SARS-CoV-2 is most often spread via droplets and aerosols floating in the air. Yet, says Joe Allen of the Harvard T.H. Chan School of Public Health, too much effort and money are still being spent on cleaning as opposed to investing in better indoor ventilation and filtration systems. In this interview, Allen describes how to make buildings healthier in the battle against Covid.

This is the first episode in Knowable’s new video series: Reset: The Science of Crisis & Recovery.

Great documentary. It's just so important we start to redirect our actions so that they are in line with what we know would actually protect us.

If we have to wash our hands or sanitize after receiving a package or putting away groceries(6:46), aren't we still accepting that surface transmission is a viable threat? If I touch those groceries again, which is kind of the point, then I have to sanitize or wash again - that seems like he's hedging his assertion.

He's the Director, Healthy Buildings Program, so his focus here is promoting Healthy Buildings. I'm not saying he's lying, far from it - the 6 foot nonsense was obviously vastly underscoped as a preventive measure, but I still wish we could get some reasonable scientific testing on virus viability on surfaces, which this doesn't touch (pardon) at all.

Thank you for this. Reminded us on where to focus our efforts against Covid-19.
