Visualization of aerosols. They are different from large droplets. Aerosols stay airborne—that’s why they facilitate coronavirus transmission. #COVID19 (this video from CO2 imaging, but similar phenomenon as smoking & virus aerosols)
2) Contrast that with aerosols when masked. Night and day. The Japanese knew it was airborne from the beginning and took measures to ensure aerosol safety early.
3) How is aerosol different from large droplets? This. Also typical air exchange usually means aerosols in air every 20 min to 4 hrs, depending on ventilation. #COVID19
4) big question is how to disperse aerosols quickly enough. Again, Japanese were ahead of the curve. This early spring video explains what is needed to clear a room’s aerosols with fresh air. #COVID19
5) Great quote by @jljcolorado on aerosols. The cigarettes smoking analogy is best — think of how often you don’t even know where the smoke is coming from, and how long it can linger inside a car or room. That’s aerosols. And that’s the problem. #COVID19

Breaking—Trump’s WH physician now says Trump has finally tested “negative” on “consecutive days” but with the controversial Abbot BINAXNOW test that led to the WH leaky outbreak in first place. Memo still suggests some lower viral load. #COVID19
2) More importantly, FDA's Emergency Use Authorization (EUA) for BINAX NOW says it is for use only “within the first seven days of symptom onset”. It is an early illness test—not a recovery test! So Conley citing it is inappropriate. #COVID19 Image
3) Notably the FDA guidance even says “Negative results do not rule out SARS-CoV-2 infection and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions” ⚠️

Omg... the overwhelming majority of Republican (men and women) who think the Coronavirus is overblown is just insane. It’s not just MAGA rally attendees, but basically 2/3rds to 3/4ths of all GOP voters who reject public health guidance. This is a Trump cult. #COVID19 #TrumpCovid Image
2) here is the actual Gallup poll. The difference is night and day on #COVID19 fundamental realities news.gallup.com/opinion/gallup…
3) the gender disparity between men and women also huge. Also persistent even when adjusting for other factors. Image

📍Beware a new Koch-aligned pseudo science group. The “Great Barrington Declaration” pushing ‘herd immunity’ to #COVID19–sponsored by a Koch-funded network that denies climate science while investing in polluting fossil fuel industries. Don’t fall for it! bylinetimes.com/2020/10/09/cli…
2) “Corporate records filed with the US Internal Revenue Service (IRS) confirm that the AIER operates as part of a Koch-funded network of climate science deniers who see environmental regulation as a threat to its vision of unfettered, deregulated markets.”
3) “The latest available IRS documents reveal that in 2018, the AIER received $68,100 for “General Operating Support” from the Charles Koch Foundation, which acts on behalf of right-wing billionaire Charles Koch.”
