@ajbirdbrain @UniofOxford @Cambridge_Uni @AlistairJarvis @michelledonelan I agree this doesn't show that seminars are high risk. But if someone in a seminar is infected, then, in the absence of good masks, there appears to be a fairly high chance that a number of others will become infected, at least if that one person talks a fair amount. 1/
@ajbirdbrain @UniofOxford @Cambridge_Uni @AlistairJarvis @michelledonelan Given the general level of infections in the UK at the moment (c. 3k new ones *detected* each day), in the absence of pretty effective testing & tracing to get those numbers down much lower... 2/
@ajbirdbrain @UniofOxford @Cambridge_Uni @AlistairJarvis @michelledonelan ...if universities hold in person small group teaching throughout the country, I'd guess that the odds would be relatively high of spread of infection through a few of these small groups. 3/
@ajbirdbrain @UniofOxford @Cambridge_Uni @AlistairJarvis @michelledonelan In any event, I think we would need well-grounded assurance that these odds are low enough. 4/4
@ajbirdbrain @UniofOxford @Cambridge_Uni @AlistairJarvis @michelledonelan Why doesn't this apply to CU undergraduate supervisions? 2 or 3 people doing a lot of talking in a room for an extended period of time. If one of them is infected, there's a decent chance of infecting the others, unless the room is large & well-ventilated. Are all CU rooms that?
