In regards to herd immunity:
Herd immunity is not a binary state. The more people who gain immunity, the lower the effective 'R' rate will be. We see this now in London. The North is seeing a larger spike because of less herd immunity - for various reasons we actually did better in the first wave in March.
At a 0.5% death rate, 13% of the population will have been infected. Current testing levels put our CFR at 0.5% for the last couple months, so between 1/10 to 1/5 people have likely had it.
When we are dealing with exponential growth, even small differences change the outcome significantly. This is why cases can only continue to rise so much before it begins to 'burn out'. I think in the next week we will hit the top of this peak before it begins to decline again. A lot of the spread has happened in university halls and education settings, which have pretty much established immunity under the groups most at risk of spreading.
Which goes back to my point on the other thread. The members of SAGE should not be talking directly to the media implying that their opinion represents the whole panel and government policy. Obviously today's briefing by Van Tam is government approved, but the stuff picked up by the media over the weekend, and duly exaggerated is dangerous. At the beginning of this, the membership of SAGE was confidential, and they were forbidden to talk to the press. The messaging was therefore a lot less muddled.
It would seem like the members of SAGE who are annoyed they are not getting their way, are the ones who are leaking to the press. Is there any scientific basis in the "circuit breaker" lockdown, because it makes very little sense to me as a policy. At most we delay the spread by another month, and then what? At that point we'll be in the dead of winter and it'll be an even worse time for it to spread.
I disagree, we have around 3000 hospitalisations nationwide. Getting them ready just in case is reasonable, but it feels more of a precaution than an urgent rush.
Do we know how many of these patients are coming in because of COVID and how many are coming in for another condition and happen to have COVID?
If the latter is often the case, then the increase in COVID hospitalisations could be misleading.
Overall, I think we lack a direction. We need to move beyond kicking the can down the road and have a destination in mind as to where we want to be by the end of the year and eventually how we plan to live with this.
Personally, I think we need to adopt a policy of once again "flattening the curve", as well as somewhat guiding the wave to places it will cause less damage. I see "Flattening the curve" involving advising people on how to stay safe, when to get tested and how much risk different activities involve.
Mass gatherings should be off the table and I think perhaps staggering the school week a bit more to slow the spread there. Face masks are a relatively small sacrifice and providing hand washing facilities in more locations is a good idea too.
