Newest MPOX aerosol study: Contagious Monkeypox found in air up to 15 ft away from patient and as high 6ft in the air. #MonkeyPoxIsAirborneToo #MaskUp 😷✅👍 Healthcare Agencies protect your staff.Tell them it’s airborne. Don’t make the same mistake done w/Covid. #COVIDisAirborne
MPOX doesn’t appear 2 as contagious as Covid via/airborne spread.Messaging matters to the public. It’d B a shame if anyone w/Monkeypox patients only depended on hand sanitizer/gloves,like they mistakenly did w/Covid. #MonkeyPoxIsAirborneToo 😷👍✅
Yesterday, the @WHO claimed:

\u201cFACT: The #monkeypox virus is NOT airborne\u201d
Let\u2019s now see what this scientific study shows us.https://t.co/5elzET88tL
This is evidence that the monkeypox virus is airborne.
Please correct @WHO\u2019s misinformation. @PeopleDocGeneva @mvankerkhove https://t.co/caH0vIFzrC pic.twitter.com/soRtGTXHjb

Thread🧵on modes of pathogen transmission. #monkeypox
Transmission is messy, and there is no single mode that pathogens employ to invade a body. Indeed, modes can change.
Plague provides a great example of this: it occurs in multiple forms, depending on transmission route. 1/13
All are caused by the bacterium Yersenia pestis
Bubonic plague occurs when infected fleas bite a person, or the bacteria enter through a break in the skin. Infection causes characteristic "buboes"
Preventative strategy would be flea and rat control. 2/13 https://t.co/xR5gdRuK53
Plague can become more widespread via the bloodstream, causing septicemic plague. This leads to black areas of necrosis in the body, hence the term, "Black Death."
As long as it doesn't get to the lungs, prevention is the same as previous - flea and rodent control. 3/13
However if the bacteria set up infection in the lungs, they can now exit the body via respiratory aerosols
This is now pneumonic plague, a highly contagious form of the disease, transmissible by air, with an incubation period of only 1-3 days & 100% fatal without treatment. 4/13
The infection control measures of flea and rodent control are ineffective against pneumonic plague -- isolation and treatment of cases, airborne precautions, and prophylactic treatment and monitoring of exposed individuals are needed. 5/13

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.
Legacy site *downloads* ~630 KB CSS per theme and writing direction.
6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors
46 unique font sizes
39 unique z-indices
https://t.co/qyl4Bt1i5x
PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.
735 rules
740 selectors
757 declarations
730 unique declarations
0 media queries
11 unique colors
32 unique background colors
15 unique font sizes
7 unique z-indices

The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.
The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
