Le Sigh - an early update of the NPHETs Exit #Covid19Ireland cases plot confirms what looks like the start of the 5th wave with
1358 cases 152% last Monday
9999 cases this week at 113% previous
With the end of contact tracing in schools we should have seen a missed case drop /1
The potential emerging 5th wave is also clear on the New Hospital Cases Plot - the doubling of case severity in the last 2-3 weeks is an unexplained concern
400 hospital is 120% last Monday
308 new hospital cases this week is 116% last week
NHC were 3.65% cases in previous week/2
Likewise ICU shows a rise when NPHETs Exit expected a fall - we did well for 2 months, now its at least doubtful
75 ICU is 117% last Monday
36 ICU admissions is 109% previous week
ICU admissions are 12.5% NHC

I'm am truth be told a little broken by this turn for the worst even though I suspected it last week. But we are where we are - a load more detail and analysis from when the hospital data was published here /4
I maintained a wishful thinking optimism even through I'd done the calculations in this thread and the patten from elsewhere was clear enough. Still a few good months & now back to a struggle but on a better terrain - there is still an exit here
A 'how can we have a new wave with 75% of the population vaccinated' thread. Short answer is Delta is a nightmare, way, way nastier than old school Covid19 because one person on average will infect 6 with no measures in place rather than 3. /1
Imagine a 100% effective vaccine that stopped transmission completely. With old school Covid once 2 in 3 are vaccinated then the virus finds 2 of its 3 previously successful jumps to other people blocked. Above 66% vaccination 1000 cases only become 900, 750, 580 etc /2
We don't know for sure but it looks like Delta infects 6 other people without measures in place. To reduce that to 1 person 5 of those would have to be blocked by 100% effective vaccine. 5/6 is 83%. So at our 75% vaccination Delta is still getting to more than 1 person /3
Last 3 days of #Covid19Ireland confirms bad news of what may be the start of wave 5. Swabs over those 3 days are 132% of the same days last week & positivity now up to 10% confirming this isn't an impact of more testing
Sat 1722, 144%
Sun 1523, 118%
Mon 1449, 136%

We are also seeing that potential 5th wave in New Hospital Cases
400 hospital is 120% last Monday
308 new hospital cases this week is 116% last week
NHC were 3.65% cases in previous week /2
Latest HPSC deaths from vaccine breakthrough allows calculation that c55% of Covid deaths in Aug/Sept were of fully vaccinated people.
BT deaths / Total / Percentage
Aug. 48 / 71 / 68%
Sept 56 / 117 / 48%
Both 104 / 188 / 55%
/1
Note with pretty much everyone over 65 fully vaccinated & vast majority (91.3%) of pre vaccine deaths in that age group this actually shows a very very high vaccine protection - but not 100% (high 90s at least). But 50 post vaxx deaths a month from endemic Covid happened /2
The HPSC report itself has a vaccine breakthrough deaths percentage of 36.5% however I think thats artificially low in terms of what we can expect because it includes a period where a large segment of the population was not yet vaccinated - Sept may be incomplete /3
Yikes, hospital cases are starting to look like the start of a #Covid19Ireland 5th wave - now really is the 2nd best time to get vaccinated if you've been putting it off.
8th of March was the last time we had 400 hospital cases so yes this is a Monday high but still a high
Vaccination is doing a great job of reducing our mortality - Eastern European counties with low vaccination rates are starting to get hammered as cases surge again but UK mortality being twice our rate is a warning that cases still come with a mortality cost /2
I abandoned posting detailed daily updates a few weeks back & switched to one big weekly one but I'm still checking the key data every day & taking notes in case the exit goes seriously wrong quickly - I'm not too happy with trends of the last few days /3
#SaveTheCobblestone now at the council buildings after marching via Merchants Arch - quite a crowd - it appears the pandemic exit may well see a significant return to street protest as we contest what that world will look like. Wall to wall hotels not being a popular option
A general comment - high levels of vaccination has allowed the risk of moving on from significant restrictions with 1/4 of the population unvaccinated (2/3 not eligible to be). In the Irish HCare context the main role 18 months of NPIs had was buying time for vaccinations /1
Our health system was too under resourced for 'flatten the curve' to have been sustainable as a route to population immunity. With too few ICUs that would have taken 5 years of switching between some opening & lockdown to avoid high excess deaths when ICUs ran out. /2
It would also have involved in the region of 40k deaths over those years - thats the IFR for a population with our age structure and where hospital oxygen does not run out. If the curve is not flattened it probable doubles or worse. But we mostly stalled Covid till vaccination/3
