BATHROOMS. RESTAURANTS. SCHOOL CLASSROOMS. OFFICES. Not just hospitals and clinics. The virus can linger in the air for hours. Forget outdated 6-feet droplet 💧rule. Huge superspreading outbreaks from aerosols have been documented. REPEAT: #COVIDisAirborne - pass it on! #COVID19

2) A single case led to a hospital outbreak - despite the max number of people just being 4. The virus stayed in the air for hours infecting many more people.

3) How is aerosol different from large droplets? aerosol study indicates that coronavirus is persistent and stable for many hours. Typical air exchange every 20 min to 4 hrs, depending on ventilation. #COVID19

4) VENTILATION is key. Both ventilation and masks needed to reduce risk indoors. But most buildings not ventilated well enough. #COVIDisAirborne

5) “Until we recognise that #COVIDisAirborne we are setting ourselves up for repeated failure”

6) Masks and aerosols demo.

7) Mask and airborne science compilation video from 2020.

8) Now that aerosol transmission of the coronavirus is established, we need to disperse aerosols quickly. Key is ventilation. 🇯🇵 knew it was airborne from the start. Here is how to ventilate your school classrooms if unable to open window. #COVIDisAirborne

9) Don’t remove your masks indoors! Even if you think you’re alone. The aerosols are still lingering in the air. #COVIDisAirborne

10) aerosol scientists were right all along, and all the airborne-denying virologists / ID “experts” who insisted on droplets 💧 need to be held accountable for their dismissive arrogance and misinformation. History won’t forget. History will remember those^ who endangered others

11) Build a CORSI-ROSENTHAL BOX 📦 do disinfect the air out of MERV13 grade air filters and a simple box fan! It’s super easy! thank you @CorsIAQ @JimRosenthal4.

12) If you wear a mask, please upgrade to more premium KN95 / KF94 / PPF2 masks. And please tighten the fit for the love of god’

13) HEPA filters are great (along with UV, CDC only recommends proper HEPA & UV for indoor air disinfection). But beware knockoffs that aren’t true HEPA. It works. Corsi Boxes next best thing.

14) But ventilation and air disinfection only part of what’s needed — Kids not only need masks, but they need HIGHER FILTRATION respirator masks, such as KN95 or KF94 or FFP2. Pediatric respirator masks are harder to find, but they are available….See 🧵👇

15) STUDENT ACTIVITIES— make CORSI-ROSENTHAL BOXES—An army of students and faculty at the University of California-San Diego are coming together to build 250 homemade air purifiers for classrooms and labs around campus.

16) Let’s follow the aerosol airborne science, not follow droplet 💧 dogma.

17) My kid will now demonstrate how to wear a mask properly. He actually made this when he was just 7.

18) Beware of intentional fake masks worn by anti maskers to deceive others… we are living in a dystopian world these days…

19) Bathrooms 🚽 are very risky - often poorly ventilated, filled with aerosolized toilet plumes when toilet lid isn’t used, and can be deceptively empty - but still infectious airborne virus remains!! Seriously, bathrooms are a real risk.

20) the virus is airborne, period. But dangerous misinfo from dogmatic @YourAlberta @AHS_media still claims it’s not airborne, despite overwhelming evidence to the contrary. Their health chiefs all need to resign or be terminated and be replaced.

21) if any health officials still say anything like these below… they need to resign or be fired

22) We should have recognized that #COVIDisAirborne long ago. We didn’t heed warnings from China that it was airborne. Was it a political or ethnic bias to dismiss China simply because Trump politicized it as a “ChinaVirus”? We should self reflect.

23) Japanese scientists 🇯🇵 also long warned it was airborne from the beginning. Was it also an ethnic or racial bias to dismiss the airborne science simply because the warnings came from Asia? Or was it inconvenient to acknowledge airborne? 🤔. #COVID19
