We need to keep shouting that #COVIDisAirborne. It is not a fear term—it is based in science and reality. Those who dismiss it will continue to endanger others and propagate the pandemic longer.
Dr Marr is one of the leading aerosol transmission experts in the world. Listen ⬇️
2) 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
3) Masks and aerosols demo
4) VENTILATION is key. Both ventilation and masks needed to reduce risk indoors. But most buildings not ventilated well enough.
5) “Until we recognise that #COVID19 is airborne we are setting ourselves up for repeated failure”
P.s. they don’t use masks in video because Australia 🇦🇺 is at almost zero. #COVIDisAirborne

Devastating record of 3251 new #COVID19 deaths in a single 24 hours were recorded in Brazil 🇧🇷 today. This spike is 40% higher than recent 7 day average. Hospitals overwhelmed. Bolsonaro today also quietly installed his 4th health minister in a year. 🧵 cnnbrasil.com.br/saude/2021/03/…
2) Brazil’s population is roughly 2/3 of the US. Thus, if adjusting Brazil’s 3251 deaths today to a US sized population, this would be equivalent to ~4800 deaths if Brazil had US pop.
3) Don’t look away. The world needs to face the reality of the crisis facing the people of Brazil, and the crushing effects of the #P1 variant, which is also now circulating worldwide as well as neighboring countries. This could all be us if we don’t collectively act.
THIS IS WILD—the NIH is expressing “concern” about information released by AstraZeneca on initial #COVID19 vaccine trial data. “AstraZeneca may have included outdated information from trial, which may have provided an incomplete view of the efficacy data” nih.gov/news-events/ne…
2) Yeah, NYT picked up on this NIH statement released just **after midnight** (unusual in itself). nytimes.com/2021/03/22/wor…
3) “Companies sponsoring drug or vaccine trials typically wait for the monitoring board to run analyses and conclude that the study has yielded an answer before they announce trial results....”
BREAKING—“A new pandemic”—Germany 🇩🇪 announces strict Easter lockdown. "What we have is essentially a new pandemic," Merkel said. The new variant #B117 is "significantly more deadly, significantly more infectious."
2) “German federal and state leaders have agreed on a radical shutdown over the Easter holidays.
Germany is extending the current lockdown through to April 18, German Chancellor Angela Merkel announced on Tuesday.
3) “The country will enter an even stricter lockdown from April 1 to April 5, over the Easter holiday period when shops, including grocery stores, will largely have to close.
Talks between leaders of 🇩🇪’s 16 federal states and Merkel lasted until the early hours of the morning”
Yes, sounds clickbait-y, but there actually was a special technique developed to enhance the vaccine to be more effective—by adding a “double proline” (2-P) to stabilize the spike.
2) “Graham’s lab had a template to work from because they’d spent several years designing an experimental mRNA vaccine for MERS.
But there’s a third, more subtle secret to their success: a tiny but oh-so-important tweak to a critical viral component called the spike protein.”
3) “Viruses multiply by dumping their genes into our cells and hijacking our cellular machinery to crank out new virus particles. But first, they need a doorway into our cells. Coronaviruses are studded with spikes, which grab hold of proteins decorating our cells like doorknobs.
“By comparing counties w/ & without restrictions, only 7% points of the 60% point overall decline in business activity can be attributed to legal restrictions."
➡️Virus was the reason.🧵
2) “Comparing consumer behavior within the same commuting zones but across boundaries with different policy regimes... While overall consumer traffic fell by 60% points, legal restrictions explain only 7 of that.” nber.org/papers/w27432
3) “Traffic started dropping before the legal orders were in place; was highly tied to the number of COVID deaths in the county; and showed a clear shift by consumers away from larger/busier stores toward smaller/less busy ones in the same industry.”
2) Belgium 🇧🇪 Prime Minister also says: “The track & trace analysis shows that infections occur mainly in two places: in school and at work,” De Croo said at a press conference at the end of the Consultative Committee meeting.
3) “It has therefore been decided, where schools are concerned, that “the ministers of education need to come up by Monday with a list of measures to limit, to the maximum, the risk of infection,” he explained.”
