and make known contact with 320 other people

Which I assume are mostly the other passengers on their flight who were already sitting in quarantine. Either that or the pair went on a doorknob-licking tour of Auckland.

EDIT: Or not! What's the cultural stuff about funerals, Hels?

Even a 'world beating' track and trace system will not find all contacts, but I'd take the task of dealing with 320 contacts of two people is a lot easier than dealing with the potential contacts of the 328 positive tests we had in the UK yesterday.

I can understand the deep frustration of everyone in the UK who is watching other countries opening up and getting on with life. It's doubly frustrating because we could be in a much better position right now.

Exactly. The analysis will have been done by the IDMC. It’s the headline look to see if it ethical to stop or continue. That analysis has shown a robust effect, hence it is time to stop. The other planned analyses will follow (including subgroups). Interestingly (for me) they have not used the standard 7-point categorical scale that everyone else is using. One measure is fraction of patients making a one and two point improvement. 7 is death btw. Remdesivir gave a modest one point improvement in mild patients.

I guess I shouldn't be surprised, perhaps I just expect too much from a heath editor/correspondent, perhaps it's a grass is always greener ?
I get frustrated when marketing or sales try and mis-describe a test result without actually understanding what was tested.

The Recovery Trial, running since March, also looked at the malaria drug hydroxychloroquine, which has subsequently been ditched amid concerns it increases fatalities and heart problems.

The antiviral drug remdesivir, meanwhile, which appears to shorten recovery time for people with coronavirus, is already being made available on the NHS.

Even here they mention hydroxychloroquine as being part of the same trial but its not even clear that remdesivir was part of this trial and Lopinavir + Ritonavir and Azithromycin aren't even mentioned.

Either way... thanks for the link. It makes me more optimistic for me personally but less optimistic overall...

Lots of weird stuff.... funerals was one but what was with preventing someone with confirmed COVID seeing a relative who was being put into a coma?

I wonder which of his dimwitted human shields will be wheeled out to take the questions on this farce at Todays Daily Briefing? Boris will be nowhere near it, that's for sure.

I'm going for Hancock. He always gets the short straw. Raab will no doubt have been gagged and locked in a cupboard after his efforts so far today

So they get in someone who knows how to deal with this app development business and within a few days has basically said that everything they've done before he arrived is crap, we're now going to do this the way everyone else has.

That's one hell of a slap in the face for the original team!

Given the absolutely fantastically successful track-record of government IT projects in the past, it's difficult to see how this could possibly have happened, isn't it?

One more poke, then I'm done, I promise! (for at least a few days, anyway)

I’d take the task of dealing with 320 contacts of two people is a lot easier than dealing with the potential contacts of the 328 positive tests we had in the UK yesterday.

Where do you stop tracking and tracing? You would need to check each of those 320 contacts for further contacts, if you really are trying to contain the virus this way. I assume there is some minimum period where a person who came into contact with an infected person is not contagious, but if it takes a few days to find and test someone who has Covid-19, the chain of ongoing contacts could be enormous.

It’s a funny one,the main thing with apps is you get it to a reasonable level then Blap it into the wild and sort out the bits your unhappy with in updates, as it’s Relatively easy to do on iPhone apps.

They wrote it without the Apple/google api so it was always in a world of pain but as soon as the api was available should have got it out.

I think it was the political wrestling the really iffy centralised data collection which turned it into a farce.

Lucky we didn't actually need it then, and we'd prefer to hear some cheery call centre worker telling us to go to Northern Ireland to get a test, then!

"Team" encompasses everyone involved in the delivery, not just the app developers and the buck stops with the government who are ultimately responsible for managing the process.

Anyone who works in IT could have told you that delivering a project of this scale would be hugely complex and Hancock's delivery dates were utterly implausible lies. That means the government have chosen to ignore expert opinion from people who understand this stuff, and just spin stories.

So did a quarter of people testing positive give false or incorrect details when they did the test? I mean, you do have to provide your details when you have a test? Please!?

"Blapping something into the wild" might be OK if you are writing a mobile phone game. It's completely inappropriate for an application which is tracking and retaining information about people and their movements, and which you expect most of the country to download and use.
There are a host of critical requirements about system architecture, security, privacy, reliability, data retention, etc, etc you need to sort out for a project like this, before you even think about writing an app, and you can't release an app of this nature without testing it to death in every scenario and on every platform you can find. You also need to stand up a serious support team to monitor performance, deal with technical issues, and provide operational call centre support for app users. It's a massive project.

I assume there is some minimum period where a person who came into contact with an infected person is not contagious, but if it takes a few days to find and test someone who has Covid-19, the chain of ongoing contacts could be enormous.

A 'world leading' track and trace system* is designed to find the contacts of the original case before they become contagious, which is, on average, 5-7 days after infection. If you can do that for the majority of cases, it makes a significant dent in transmission, even allowing for people who either cannot be contacted or can't be identified.

You can't stop all transmission, but if you stop most of it, through adherence to social distancing measures, good hygiene and robust track and trace, then the number of cases will stay low enough to allow everyone to resume a fair amount of normal activity - work, school etc.

*Some sarcasm possible

Thought you were just blowing your own trumpet there for a minute.

Time for some PROPER rioting then, none of this peaceful shit.

is designed to find the contacts of the original case before they become contagious, which is, on average, 5-7 days after infection.

Where is that number from? I struggled to find good info on this, but here is one source:

https://www.health.harvard.edu/diseases-and-conditions/if-youve-been-exposed-to-the-coronavirus

The time from exposure to symptom onset (known as the incubation period) is thought to be three to 14 days, though symptoms typically appear within four or five days after exposure.

We know that a person with COVID-19 may be contagious 48 to 72 hours before starting to experience symptoms. Emerging research suggests that people may actually be most likely to spread the virus to others during the 48 hours before they start to experience symptoms.

With those figures, it is possible for someone to become contagious from 2 days after contact with an infected person. They then have 2-3 days being contagious before starting to notice any symptoms. I'm not sure if the track and trace allows self-reporting (which, I'm sure, would result in every sneeze being reported as Covid and everyone ending up back in isolation), but if not, it would then take a further few days to get tested and receive a result. I still don't see how these figures stack up to make a useful system. Personally, I think that flattening the peak is about the best we can do, but only time will tell.

It's possible yes, but my figure (5-6 days actually, apologies) is the average from the WHO. Some patients take 14 days from infection, and there may be a pre-symptomatic period where patients are contagious in some form. As I said, you won't catch all contacts before they become contagious, but if you catch the majority, that will put a brake on transmission, if you are doing the other stuff instead.

It's not an area where there is a simple answer that will get it behind us and back to normality. A combination of lots of things is needed, including public cooperation with lockdown, even if individual actions don't seem to carry a lot of risk.

I don't disagree, but you wanted this er like a month ago and we are in the middle of a pandemic,its not normal times, you don't have the luxury of time.

Sorry, @martinhutch, still don't agree with your numbers. You say 5-6 days is quoted by the WHO - according to their website, that's the incubation period, that is, the period between contact and symptoms starting.

A person is contagious for up to 72 hours before the end of the incubation period, which means it's typical to be contagious within a few days of contact. I am nit-picking over numbers, but IMHO this is the difference between a track and trace approcach working, and it not working.

Unless you count the four months from the point at which they were warned and should have known they were going to need it, but our leaders were still fapping themselves raw over 'taking back control'.

I'm not quibbling with you over that. T&T will not catch all contacts, or identify every case. What it has to do is to find enough reduce the burden sufficiently (alongside other measures) to make sure case number do not start to grow rapidly - and identify local hotspots which may need lockdowns as an additional measure. I think my original point was slightly lost - that if you have anything other than very low numbers to start with, that job gets a lot harder. It's still worth doing, obviously, but we have to accept that our government's failures mean that we are comparatively worse off than other countries.

In short, it would be fantastic to be anywhere near NZ's position, because then you can use T&T in the way it was intended, to respond quickly and accurately to smaller numbers of reported cases while the rest of the country is allowed to get on with life. But it's still worth pursuing it here in conjunction with other measures, because done properly, it will help.

Yep i do like to bang on about them not raising the drawbridge earlier.

Seems weird to have taken back control of our borders to only not to.

That’s the way to post it!

Much better than vague links without context or explanation [ I’m guilty! ]

Anyway, good news… I genuinely feared they’d keep doubling down on their obvious mistake*, even if it meant no app or a poor app.

[ for the record, I see it as a decision not a mistake… I think key people saw an “opportunity” worth pursing despite the technical limitations and risk of low uptake - and I don’t mean a money making opportunity, I mean a data capturing/analysing one ]

There needs to be a public inquiry on this

We started developing an app with VMware in Jan. Apple/Google announced their approach 10th April, we carried on and impact assessed the new approach in parallel in May (tested both on the Isle of Wight), decided to switch in June.

Turns out our app is better at determining the distance between phones, but unreliable on Apple (surprise surprise).

Google/Apple solves the reliability, but it's crap at the distance bit. Ongoing discussions with Apple and Google.

I agree we're hardly fleet of foot - but public enquiry?

Do you have any idea what the normal contact rate is for an outbound call centre? Or do you think that you just give someone a call and the right person answers first time, every time.

I'm actually very interested in these answers, because I've not had much productive discussion about how these approaches will work.

What it has to do is to find enough reduce the burden sufficiently (alongside other measures) to make sure case number do not start to grow rapidly – and identify local hotspots which may need lockdowns as an additional measure.

I'm not sure it does help - the workload for one confirmed case is enormous. Also, how do you lock down a local area?

Let's take the averages of the provided figures, so the incubation period is 5.5 days, and you are contagious for the 48 hours before that. You notice the symptoms a day after the incubation period, self-isolate, and then it takes 4 days to get your test, send it back, and get the result. We're now on day 10.5, and you can inform the track and trace system. However, you were out and about up to day 6.5 in this best-case scenario, and contagious from day 3.5 onwards. In those three days, let's say you saw 30 people. Those 30 people have now had up to 7 days to spread the disease, which is plenty of time to start a second and third chain. You'd quickly end up with thousands of people to contact from a single case, unless you ignore the secondary chain effect, in which case there isn't much point to the whole thing.

IMHO, the only reasonable chance a country has of beating coronavirus (and maintaing anything like a reasonable life for its citizens) is a very hard lockdown, followed by a complete and practically permanent closure of their borders. If it really is as infectious as we think, there isn't much else to be done.

That means the government have chosen to ignore expert opinion from people who understand this stuff, and just spin stories.

My honest opinion is it's "Enterprise" syndrome.
Captain .. "How long will it take to get the warp core stable and online?"
Chief Engineer "about 12 hours if we work round the clock"
Captain "You have 3 hours"

of course it always works on TV ... sign of leadership etc.

A belief by management types that experts just need to be told to do it quicker or in this case...

Captain .. "How long will it take to get the warp core stable and online?"
Chief Engineer "we ejected the warp core and it exploded into atoms"
Captain "You have 3 hours"

ThePurist - isn’t that exactly the problem? Anybody with expertise has called for local solutions - actually knocking on doors - rather than a huge centralised call centre approach.

Not sure about your maths, but your point is spot on. Which is why you need thousands of staff working on this even with small numbers of new cases. Which is why you need to be at the point of having low to no cases before relaxing lock down and relying on track/trace/isolate. Again… we’re not there, but are acting as if we are.

a very hard lockdown, followed by a complete and practically permanent closure of their borders

True, and many counties included NZ did just this… but, medium term, you only need to keep borders closed (or quarantine in place) for those coming from high risk counties. See what’s happening in Scandinavia, borders are reopening, except for Sweden, because it didn’t do a very hard lock down.

That's a separate issue to the effectiveness of the call centre, which (compared to the area I'm familiar with) is actually doing a pretty good job of reaching people by phone. Of course there will always be some people you don't reach by phone, but there will also those you don't reach by going and knocking on the door. How many times will you send someone round to their house to try to contact them? They could be out working, shopping, exercising or even testing their eyesight. There's no magic solution that will guarantee 100% coverage.

This app farce is just obscene. Somehow, the British government procured an app that recognises 75% of Google devices with which it has contact (not good), and only 4% of Apple devices.
4%!! So if a super-spreader of COVID comes into contact with 50 iPhone users, it will pick up 2 of them.

How is that even possible?!
