@attackedbycritters it says in the title the last 10 days
@bigchocfrenzy that graph is a little misleading in that if few people are infected then you have no positive tests at all, and it follows that if almost no-one is infected then testing isn't particularly the point. the graphs would make sense more if you looked at the % positive over time AS WELL as the test count.
the problem in the UK was that the NHS is apparently completely shit at responding to a developing situation and scaled up its testing incredibly slowly and this killed thousands of people. this was known weeks and weeks ago. recall that in early March covid-19 test counts were reported daily on the government website with the daily positive count, before we had daily death spreadsheets.
I posted about the test counts here in March: www.mumsnet.com/Talk/am_i_being_unreasonable/3863339-Stay-local-to-exercise-is-rubbish?pg=6&messages=100#prettyPhoto/0/
Tests per positive is a daft measure as I observed in that thread, the number of positive tests is meaningful only if you have a consistent testing policy.
In the UK TODAY we had around 5% positive. www.gov.uk/guidance/coronavirus-covid-19-information-for-the-public That is 3,446 out of 71,644.
We have three different reasons for testing which are different from those in March and far more being tested, which makes it difficult to compare results with ourselves let alone other countries.
However our Pillar 2 are something like 3-4% positive, and Pillar 1 5-7%.
It follows fairly logically that our current infection rate is likely to be south of 4% for the population as a whole, and insofar as we now have mass testing, a fall in this rate is a good thing.
However I don't think we could argue that it's symptomatic of a current governmental failure that we test 1 in 500 of the population daily, whereas New Zealand has never tested that much of the population on a daily basis.
It's more that the UK government failed completely when its testing infrastructure was pisspoor and utterly overwhelmed by a ludicrous 40% daily positive rate in late-March early/April, when we were testing just 1 in 10,000 of the population daily, while the Kiwis were testing four times as many at the same time.
In particular, their 1 in 2500 of the population test rate was achieved at a time when their daily positive count was only 3%, and they responded by testing even more of the population daily.
We had achieved 3% daily positives a full 3 weeks before they did (which of itself shows that they had a massive time advantage over us), and when we reached 3% daily positive, our tests were only around 1 in 40,000.
The failure to scale up very hard and very fast spoke for us. By the end of March it was far too late, and that 40% daily positive test count spoke to thousands of people who we could do nothing to stop dying.
Recall that because NZ had a MASSIVE time advantage, when they shut the borders on 19 March, as it was essentially within a day or two of the pandemic really starting in NZ. The equivalent would have been locking down around 4th March in the UK, which is before even Italy locked down.
