It may not be 100% effective but neither are actual tests. I’d much rather be sent home with a temperature as a potential alert and find out I’m ok than go somewhere and later find I had covid and risked spreading it (and vice versa) |

Palpation of the skin in the diagnosis of fever is highly unreliable. The presence of fever is underestimated by palpation in 40% of individuals, even when the measured temperature is as high as 39°C (102.2°F). ncbi.nlm.nih.gov So false negatives are up to 40%. I'm pretty sure South Korean scientists (medical and socail) have access to all this. Still means 60% of people with fever are stopped from getting on the bus. In *that* society, this might well make sense. Certainly I'm in no position to say it's bollocks. |

"It may not be 100% effective but neither are actual tests." *Bangs head on desk* Quantify the uncertainty in the testing method. And then compare. My point is that Uncertainty in "real test" <<< uncertainity due to skin temperature testing for CV19. If Unc(real) < unc(thermal) then it might be worth doing, but it's defining how big the uncertainty in one method is compared to the other that is critical. Uncertainty in science is crucial if we want to compare things. |

5 live science did a thing on UVC a few months back which was really interesting. They're testing a very limited spectrum range now to see if the 'disinfection' without the risk of any harm to living cells. In that way they could have 'real time' disinfection where people are, say in tube carriages.

I wish more people would be sensible And considerate here by checking their temperature before getting on public transport generally - not just for Covid. Would help stop spread of colds and flu and save us from the constant sniffling. Big storm about to hit, disconnecting outdoor electric supply just as a precaution not waiting for the first flash of lightning.

PtB - that's an error in one direction only too. And 40% is enormous for a diagnostic test! You also need to quantify false positives to get an idea of the true uncertainty. Plus it's missing asymptomatic people anyway. But 40% is more than enough to suggest that it's not doing much. |

We had 10 hours of non stop lightning and thunder on Tue night BKev. Edinburgh internet outages, Falkirk houses struck by lightning and a butcher's razed to the ground.  And obv the terrible flooding and landslips causing road and rail accidents.

Analogy. If I said that the criminal justice system had a 40% error in failing to secure prosecutions, would you suggest that it had good efficacy. If then you say that the justice system had a 30% error in the opposite direction as well, how about then? If we're also missing 30% of cases in the first place? OK, being excluded from an activity is not the same as being locked up/not locked up/not detecting crimes, but the analogy works well enough. |

Kids pick up bugs all the time & as we all know can ge violently sick one minute & find the next - would that bus system thing exempt them if it picked up a higher temp? I’m with fozzy (not often we’re on the same wavelength!) Far too much uncertainty to make it a way of deciding if you can get on a bus or not. Wide open for abuse too - would make a change from the usual excuse ehh you godmother made it to work/school! Ref the ozone thing mentioned - wouldn’t that be v had from an environmental impact? It seems like we are getting completely phobic/obsessive about getting ‘clean’ ‘safe’ which will surely decreases not increase inbuilt immunity responses long term? |

I typed Why you hadn’t made it to work/school - not sure why that auto changed to godmother!
