I'd thought it was known for some time that tiny airborne droplets (i.e. those which can travel further than a short distance) were a risk if you were present downwind or in a poorly ventilated space for a prolonged period - because the tiny airborne particles will carry fewer viruses then big droplets, so exposure needs to be longer to achieve an infectious dose.
This is why opening pubs and restaurants, car sharing, etc is a bad idea? Because distancing doesn't work in unventilated spaces?

This was in that contact tracing blog post that was linked to in pages past. Is this only now just becoming properly evidenced?

I read the article 

My surprise is that this is only just becoming accepted. It was described on here over a month ago. My question (if you looked at it) was why the change in position now. Has the evidence only just now gone through peer review? Does the WHO require a large body of corroborating evidence to change its mind? Perhaps the WHO has been reluctant to acknowledge it until now because it means that economic restart will be hampered (not to mention the difficulty in communicating the new health message to "stay 2m apart unless you're indoors in which case don't be too long") - though of course, economic restart is not within their remit.

So as per my posts on B3 from here: https://ukbouldering.com/board/index.php/topic,30489.msg603070.html#msg603070

There's now more evidence to back this up.

Preclinical research on NR and its role in covid-19 infected cells has now been released today in pre-print form, available here: https://www.biorxiv.org/content/10.1101/2020.04.17.047480v3

Note my disclaimers - I'm a shareholder in Chromadex (which are up 22% on this news)

Further research adding evidence to the B3 / NAD+ hypothesis.

Update on this. The next pre-clinical study was released last night US time. It reinforces the hypothesis that's been building around NAD depletion leading to worse outcomes from covid-19 infection; and the role of NAD augmentation using NR to slow virus replication.

Human study coming soon..

Re-infection and non immunity cases appearing... Stone flagged this up on FaceBook

My friends in the Cotswolds have the recurring problem: they recover a bit then get ill again, and again. 5 bouts so far. They were fit and healthy triathletes in their late 50s.

[petejh]

Hearing more and more stories about very fit people in their 50s and 60s suffering life-changing conditions. A climbing friend was telling me this the weekend about his super-fit friend in his 50s who caught covid and suffered a stroke due to it. He said out of all his friends in that age group this was the last person he'd have guessed would fare badly. Seems a lot of the outcome is down to the reaction of the individual's inflammatory response, which is hard to predict. 

[tomtom]

Oof 1240 new cases today... I know the numbers fluctuate alot, but thats 9 days after the shops, bars and restaraunts were allowed to re-open....

edit - c400 - looks like the 1240 figure includes a load of previously uncounted pillar2 data from Wales... as you were

Good recent episode of More or Less https://www.bbc.co.uk/sounds/play/p08kdnbp

Probably not that surprising, but more dirt on how shit the government 'testing' figures are. In particular they count tests as they're sent out to people (obviously no actual testing has taken place at that point), and they have now admitted that a full 2/3rds (or 2 million) of these posted home testing kits did not actually end up in a test happening (e.g. courier left testing kit in a puddle so it was unusable, went missing in post etc.)

Some interesting analysis of the swedish strategy too.

Just wondering with masks becoming compulsory in shops has anyone bought one that they can recommend? Been looking this evening and there seems to be a massive variation in materials used and costs.

I’ve got a couple of cloth ones and Tbh I prefer the disposable type ones with earloops. I find them a bit lighter and less scratchy than the cotton ones (one made for me by mother in law) and they have a metal/bendy strip along one side to pinch over the nose a bit.

I got them online - and they’re the same brand as the ones my wife is given at work (NHS).

I use them like reusable ones - but ive only used them when dipping in and jut of a shop.

Problems reported with Reiff camping

Doesn't sound good. I miss the old campsite at Achnahaird.

I’ve had three in total. The last, two weeks ago was the worst.  No respiratory problems thankfully but I was out of it for three days and am still recovering.  Much worse than the first bout back in March.

[mrjonathanr]

Sorry to hear that Ben. Hope it fades now.

[sdm]

A few days old but data from the ZOE/Kings symptom reporting app suggests that cases can be grouped by their early symptoms. These groups are good indicators of how serious a case is likely to become and whether it is likely to result in hospitalisation and ventilation. They remain good indicators even after considering age and existing conditions.

Tl;dr if you develop shortness of breath, neurological symptoms such as confusion and gastrointestinal symptoms such as diarrhoea, be very concerned.

[tomtom]

Sorry to hear that Ben. Hope it fades now.

Yes - that sounds grim Ben

[Falling Down]

Thanks guys - I’m mostly OK now. Just have tinnitus, sore eyes and tiredness. Had a long walk round the park yesterday that felt tiring but hasn’t knocked me out thankfully. Having a real pint in a pub was amazing.


I did test the weekend before last after speaking with a GP to see if I had been infected twice or whether it’s a long term thing but somehow managed to balls up the scanning of the barcode on the sample and never got the results so did another today. I’m sure that’ll come back -ve so will do an antibody and a T-cell test if I can.

It weighs on the mind a bit. Like, have I got something that’s going to keep coming back?  I’d normally be doing press-ups and stuff in the morning and the odd run but just don’t have the energy.

Will keep you posted.

[andy popp]

Shit Ben, I am so sorry to read all this; I had no idea. Get well and stay strong.

[Will Hunt]

Not quite concrete evidence, but a promising development for users of crags and walls. Sharing holds maybe not the problem we thought it could be (provided you chalk up).

[SA Chris]

"So, if we put the chalk inside the body by, you know intravenously, like an injection or something, then the next day, the virus could just, kind of, vanish. And you experts are looking into that, right?".

[Offwidth]

I see the chalk where it knocks it out in a minute. One minute. And is there a way we can do something like that, by injection inside or almost a cleaning. 

[Oldmanmatt]

Yeah, but you can’t moan at people that don’t brush after an especially chalky session, now.
