2/ "We have known since early 2020 that visors without masks are worse than useless at preventing Covid-19 transmission.
"Despite that, many people believe that they are effective, and wear them in the false belief that they are protecting themselves and/or others.
3/ "As Chair of the BMA Public Health Medicine Committee, I was closely involved with BMA messaging to try to correct this false belief - I can't seem to find the infographic we created on the BMA website any more, but see eg bma.org.uk/news-and-opini… .
4/ "I am appalled that, a year and a half later, I STILL see people wearing eye protection. This supports the false belief that it is safe and appropriate to wear a visor without a mask to prevent Covid-19 transmission.
5/ "I may have complained about this during last year's Strictly run; I am appalled that BMA is still promulgating this Covid-19 misinformation.
6/ "Please STOP. If a mask is required to control Covid transmission, please ensure that a mask meeting at least FFP2 standards is worn, to model the correct behaviour.
7/ "If lipreading is an issue, consider using a powered air-purifying respirator (PAPR) or a facemask with a clear panel so the face can be seen (these have been available since the start of the pandemic)."
1/ Following the Prime Minister's decision to be photographed, in Hexham Hospital, without a mask (despite everybody around him wearing one), I thought I'd look out the current guidance.
2/ (He clearly made a point of being filmed and photographed without a mask, and ensuring that those images were widely circulated…
3/ (…Whether this is a defiant dig at the mask-wearing rules he knows are necessary, but he hates, or another of his "dead cat" distraction ploys to draw attention away from gathering scandals, it was clearly deliberate.)
1/ People with a Great Barrington Declaration bent ("don't do anything to control Covid-19 and hang the consequences - who cares how many people will die...") are now attacking the rest of us for saying we should continue to do what we can to control the disease.
2/ "You want it to go on for ever", they say, echoing the prime minister's "if not now, when?" questions.
It's a complete straw man attack. We have never said that.
3/ There are some discussions about whether we should try to eradicate the virus completely; or just bring it down to controllable levels.
But nobody's saying we need to take precautions for ever.
We needed more single rooms, ideally with negative pressure lobbies, to prevent transmission of airborne diseases.
Covid-19 won't be the last such pandemic.
So, if only for infection control purposes, we need more such rooms.
And yet…

I looked into the regulations during the flu pandemic.
Not only were there no standards for the number of respiratory infection safe rooms a hospital (even new-builds) should have, regulations on eg the minimum distance between beds were extremely weak or non-existent.
3/4
It has long been policy to vaccinate eg HCWs against chickenpox if they are not immune and, using effectively a bigger dose of the same live-attenuated virus vaccine, to vaccinate older people to prevent shingles.
1/
2/ I am a little uncertain what to make about this huge twitter storm about sewage.
tl;dr - it is a hazard; but it's a very low level of risk to health or to the environment.
There are more important things to worry about.
3/ Until I retired in January, I have been a consultant in communicable disease control since Feb 1998. Part of this job has always involved liaising with water companies over incidents etc., and with emergency planning bodies including local authorities.
