I& #39;m devoting a single thread to her comments (originally posted on Facebook & reposted on Twitter with her permission), since I do not think their significance has yet fully registered with higher education, government & public health officials. 2/
On the CDC& #39;s (linked) "How COVID-19 Spreads" webpage, talking is also listed alongside coughing and sneezing, in the second of four bullet-pointed means by which the virus "mainly" spreadshttps://abs.twimg.com/emoji/v2/... draggable="false" alt="πŸ‘‡" title="Down pointing backhand index" aria-label="Emoji: Down pointing backhand index">. 4/

Why does the CDC group something as apparently innocuous as talking together with coughing & sneezing as a significant risk factor? 5/
Because of mounting evidence, via case studies (some w detailed CDC analysis), that talking (or singing) was the most likely means by which Covid-19 was spread from a single individual to many others indoors, more than 2 meters away, via inhalation into their lungs. 6/
https://abs.twimg.com/emoji/v2/... draggable="false" alt="πŸ‘†" title="Up pointing backhand index" aria-label="Emoji: Up pointing backhand index">is of special relevance to this thread, since a large lecture, generally involving a single speaking individual, at some distance from the audience, is akin to @jonkay& #39;s red-underlined events that are absent from the list of SSEs. 9/
In addition to noting this fact in 1/https://abs.twimg.com/emoji/v2/... draggable="false" alt="πŸ‘†" title="Up pointing backhand index" aria-label="Emoji: Up pointing backhand index">, Deborah Cameron also draws attention to the respects in which small, participatory group teaching shares the risk factors of various catalogued SSEs. 10/
Why, then, are universities such as @Cambridge_Uni moving apparently less risky events online (large lectures), & trying to keep the apparently more risky events in person (small group teaching)? 11/
