I'm one and we were given links to tell us how to deal with tasks such as shopping for other people ie how you take their card/cash, how you leave their shopping at the door etc etc Google it up and give it a try 🙂 Just seen your last post about getting priority access - glad you're sorted Good on you Mark, we have a great local response team here and a really good facebook group for support. Hopefully we will come out of this with a much stronger sense of community .👍 1 Share this post Link to post Share on other sites

Easy to criticise others i.e China or USA and their numbers but our own don't really stack up either or compare as with say Germany. So - let's not blame anybody or claim we are any better/worse but get real hard facts. Meanwhile err on the side of caution as per the government extended lock down until we know better. If any European nation is fiddling the figures then they are all fiddling much the same. Spain and Belgium looking worse than average, Germany and Austria better than average. not much more than a fag paper between the rest.

We have no idea how many are infected because large numbers show no symptoms and probably never know if they have had it. Also those infected will have their infections over a long period of time and not all at once. The only certainty we have is that those diagnosed as infected will follow two pathways, roughly 80-85 % have a very mild condition and will never need hospitalisation, roughly 15-20% need some form of hospitalisation and of those some 3-5% will need intensive care. These figures seem to be consistant across nations and there is more than enough data to confirm this. The variations we see in deaths will have many causes, variable health care, social conditions and living in close proximity to large conurbations are only a few of many. Inevitably some countries will fare worse than others. Share this post Link to post Share on other sites

Inevitably some countries will fare worse than others. The 4% came from the Dutch studies as reported on here (was it Mark Y) and from memory correlated with other data elsewhere. I actually halved it to 2% for the sake of argument and assumed population of 50M - makes my numbers easy (1M 'infected' to date) for 10% (not the 12-15 quoted) then needing hospital give 100K hospital patients. Clearly 100K patient are not in hospital (but could be at the stroke of the pen if we of took in all the care home cases !). As to the timing - given that it's a fast exponential growth the vast vast majority of such patients should be recent - last few weeks - not in February or even March so the approximation is valid. So something doesn't stack up with the numbers or more likely interpretation given. Share this post Link to post Share on other sites

Yes, I don't think there is anybody on here who hasn't know that from the start Ricardo. I personally like to look at the daily net number of hospital admissions because I know that if it continues it's current downward trend that : 1. The number of daily reported deaths will follow it down 2. It means we are freeing up the capacity to permit the first stage of easing of the restrictions 1 Share this post Link to post Share on other sites

Yes, from the NHS webite, the highest actual daily number of deaths was on the 8th April with a total of 792. The reported figure for that day was 938, so even allowing for a few more "late recordings" the actual deaths, although a tragic figure, will get nowhere near the quoted "headline" figure. 1 Share this post Link to post Share on other sites

T 190 Posted April 17, 2020 I think the Dutch blood tests actually showed 3pc. The UK estimated 4pc The UK was doing general testing at the start so would have an idea of the overall infection rate compared to those being hospitalised. No doubt scientists are also sharing unpublished data internationally eg Germany did a random sample laboratory blood testing of 3000 people in Munich recently for antibodies which hasn’t been reported but would be known in the scientific community.The sample size would have normally been selected to give you c95pc certainty of the infection rate as this is the most efficient point between sample size and certainty Munich was presumably chosen as it has been suggested it was the entry point for the disease into Europe from China. 1 Share this post Link to post Share on other sites

I don't think a number of few percent is in much doubt. TBH, YF, I don't have much faith in the data yet. What we have is useful to plan what we do but we won't have a full picture on the extent of the virus yet, nor reliable comparative data. My most confident guess, is that it has been under reported everywhere. At a low point of my career I worked in local govt (relatively short lived) and one of my duties was to sit on a data committee that use to try to model data. It is much harder than you would think because the data that you want largely isn't available. The data that is gathered is usually for a specific purpose which does not fit very neatly when you try to re-purpose it + there are varying practices of recording it which call into question the reliability of the data. e.g. Doctor A may be happy to put covid on a death certificate without a blood test whilst Doctor B isn't (I made that up, as a possible example, don't know if it's true). You then have to go through a statistical process to adjust different sources of data in different ways. Ultimately, I think that the most reliable way may come from comparing historical death rates over time, but I'm not sure what sources are available (apart from the obvious ones). Sorry - a very, very long-winded way of saying I don't know! 😳 1 Share this post Link to post Share on other sites
