Masks and respirators for prevention of respiratory infections: a state of the science review
SUMMARY This narrative review and meta-analysis summarizes a broad evidence base on the benefits—and also the practicalities, disbenefits, harms and personal, sociocultural and environmental impacts—of masks and masking. Our synthesis of evidence from over 100 published reviews and selected primary studies, including re-analyzing contested meta-analyses of key clinical trials, produced seven key findings. First, there is strong and consistent evidence for airborne transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other respiratory pathogens. Second, masks are, if correctly and consistently worn, effective in reducing transmission of respiratory diseases and show a dose-response effect. Third, respirators are significantly more effective than medical or cloth masks. Fourth, mask mandates are, overall, effective in reducing community transmission of respiratory pathogens. Fifth, masks are important sociocultural symbols; non-adherence to masking is sometimes linked to political and ideological beliefs and to widely circulated mis- or disinformation. Sixth, while there is much evidence that masks are not generally harmful to the general population, masking may be relatively contraindicated in individuals with certain medical conditions, who may require exemption. Furthermore, certain groups (notably D/deaf people) are disadvantaged when others are masked. Finally, there are risks to the environment from single-use masks and respirators. We propose an agenda for future research, including improved characterization of the situations in which masking should be recommended or mandated; attention to comfort and acceptability; generalized and disability-focused communication support in settings where masks are worn; and development and testing of novel materials and designs for improved filtration, breathability, and environmental impact.

Low-cost measurement of face mask efficacy for filtering expelled droplets during speech
A simple method was developed for evaluating the efficacy of face masks to reduce respiratory droplet emission during speaking. , Mandates for mask use in public during the recent coronavirus disease 2019 (COVID-19) pandemic, worsened by global shortage of commercial supplies, have led to widespread use of homemade masks and mask alternatives. It is assumed that wearing such masks reduces the likelihood for an infected person to spread the disease, but many of these mask designs have not been tested in practice. We have demonstrated a simple optical measurement method to evaluate the efficacy of masks to reduce the transmission of respiratory droplets during regular speech. In proof-of-principle studies, we compared a variety of commonly available mask types and observed that some mask types approach the performance of standard surgical masks, while some mask alternatives, such as neck gaiters or bandanas, offer very little protection. Our measurement setup is inexpensive and can be built and operated by nonexperts, allowing for rapid evaluation of mask performance during speech, sneezing, or coughing.

I think it’s time to elevate the Atmosphere branding as ‘your everything-account for the Internet’. Bluesky is not “the last social identity you’ll ever have to create”, your Atmosphere identity is. Bluesky = one of many Google apps Atmosphere = your Google account

my initial though is that if we expand the PDS account manager and have most major account actions take place there, it could help. eg, similar to how youtube would probably direct you to google accounts for full account deletion, and then it is clear that impact goes beyond youtube
It’s not lost on me the impact of my latinidad and the team behind Blacksky being responsible for creating the Atmosphere’s first medical platform. People historically abused & underrepresented in medicine are responsible for building the foundation for its community here. Don’t forget that.
the terminology for the atmosphere has to be able to elicit the response "oh that's bluesky i think?" before it can get any other type of response out of the general public. right now we don't have anything that does

www.youtube.comI will say that the use of the word “Liquify” during the atmosphere report today was very ill advised lol…. That *really* feels like synonym for sloppifying given the context. Not a value judgment on attie, but I feel like that one should have been caught given the topic. #atmosphereconf
Thing I've been thinking about lately that is unique to the atmosphere. In this post @aaron.bsky.team talks about the need for a clear TOS violation on Bluesky before action can be taken. There's also the principle of only taking action based on, on platform behavior.
Moderating With Humans, For Humans
aaron.leaflet.pubin a community like ours, i think it’s tacky to say “stop using [Atmosphere app] and use [other Atmosphere app] instead” when i released @aturi.to i didn’t tell people to stop using @pds.ls or @atproto.at with @anisota.net, you won’t find me saying “ditch bluesky, mu, blacksky, etc”
I wish the Atmosphere had content warnings (like on the fediverse)... because I'd like to show you the limits of free speech absolutism and the kind of content that is allowed on #WSocial: blatant racism, xenophobia and transphobia. X vibes... but hey, it's "hosted in Europe" 😒
