      We urgently need to focus on ventilation. Six months into a respiratory pandemic, we're still not given sensible and practical guidance against short-range aerosol—airborne—transmission of COVID.

      There's strong accumulating evidence that, under the right conditions, COVID can be transmitted in ways that are not currently reflected in our guidelines. People urgently need to understand what's happening and why so they can take the correct steps to mitigate. Crucial for all.

      Some steps to mitigate short-range aerosol transmission are cheap, even free. Some are expensive and require needed upgrades to our infrastructure. There is also a lot of unnecessary fear and scaremongering! Don't fall for it.

          Ventilation in July is like masks in March. There's accumulating evidence AND many practical steps to take. Some are within our reach for free or cheap, and we should prioritize the expensive ones. Instead, we're stuck, without guidance.

          Correctly understanding the specifics of airborne transmission of COVID is *really important* because it changes many things about our guidance on masks and distancing like who should mask? When? How? When is six feet not enough? Should we mask outdoors? https://www.theatlantic.com/health/archive/2020/07/why-arent-we-talking-more-about-airborne-transmission/614737/ …pic.twitter.com/Q2i5QPOTtc

          Yes. Taking short-range aerosols plus superspreading seriously has implications for almost every aspect fighting COVID. Japan, which long took airborne transmission seriously, does contact-tracing differently (cluster-busting) exactly for this reason.https://twitter.com/bendadams/status/1288858770983006208 …

          There is urgent need for practical guidance for schools and other indoor spaces. For now, see thread from an excellent scientist. Lack of official guidance means there is a lot of snake oil in this space. Basic HEPA filters work, though. See for details->https://twitter.com/CorsIAQ/status/1288739096148336642 …

          16/ The activated carbon is harmless, but does little to remove particles & is usually insufficient in mass to remove VOCs/odors. Not needed. Remember, basics! Aim for a portable air cleaner with a HEPA filter & CADR (for smoke) > 300 cfm (see above)

          (1/2) Are searching for an air cleaner? 1st, I recommend HEPA only for COVID risk mitigation indoors. Want to treat a 600 sq ft room? FYI an air cleaner with a CADR of around 400 cfm will give you 5 air changes of particulate-free air (assuming an 8 ft ceiling).

          Exactly. Aerosols are like short-range mist—the closer you are to the person emitting it, the more exposure *but* under the right conditions (poorly ventilated indoors space), the mist can accumulate and even be pushed around by air currents beyond 6 feet. https://twitter.com/dylanhmorris/status/1289612851762667521 …

          💪🪟 Thrilled to see the message about the importance of ventilation *finally* breaking through to the broader public (at least, I hope so!). (Sane policies for/media coverage of the safer activities outdoors, maybe, too, one can hope?)https://twitter.com/misguidedsoul7/status/1291069337600774144 …

          Why important to understand the role aerosols may play correctly even though they, too, cluster in close-range of the person. Droplets=only in front of one. Aerosols=escape behind one if mask is poorly fitting. Keep your mask on indoors even at distance.https://twitter.com/jljcolorado/status/1280935408398766080 …

          Short answer: Hepa filters with no gimmicks (ionizer, UV) are good for unventilated spaces. Higher CADR (smoke rating) is better. If you can open windows/doors for good air circulation, better. Better answer: follow @jljcolorado @ShellyMBoulder @kprather88https://twitter.com/__apf__/status/1292085934767316997 …

          I wish there were guidance on whether high quality HEPA air purifiers that change the air several times an hour are useful indoors, and when or whether that's better than opening windows. (In winter, are we going to need to freeze, or will air purifiers substitute?)

          Thread below with some answers. Also more experts to follow: @linseymarr, @corsiaq, @JimRosenthal4, @stephensbrent. That said, it's past time for CDC to step up and give us guidance on ventilation. As I wrote, Japan has been doing that since the beginning.https://twitter.com/jljcolorado/status/1291760621822726145 …

          7/ Selecting HEPA cleaner, DO NOT want ones that also have UV, ions or other bells-and-whistles. More $, don’t help, can be dangerous (see below). Filter already capturing the virus, which will decay there. Just change filter carefully, put in sealed bag, wash hands

          The dearth of communication from health authorities on even the most basic questions like the one below is maddening. The few experts on social media are doing what they can, but it's really time for the academy to form it's own shadow CDC to communicate.https://twitter.com/zeynep/status/1291777886014365696 …

          Fourth option: it's more that person's problem than people around them. The virus seems to mostly spread *out* in drops of various sizes through the mouth, but is inhaled *in* and attaches well to the ACE2 receptors in the nose. Mouth-only mask is less protection for the wearer.
