The person in the supermarket or on the train are also family members to someone so you’ve just answered your own question that it’s easy to trace family members .

 

That's not what he's getting at. He's saying it's easy to trace somebody's family members (including family members of a Tesco worker or tube rider) but how can you possibly do the same for the other people they've come into contact with? Every customer that's been to Tesco for the last week or has been on the tube at rush hour in the last week?

 

Why is it easy for some and not for others ?The testing theory is relative to the whole nation not one individual .

 

It's easy if you don't encounter many other people. It's more difficult if you encounter lots of other people.

 

You can't trace everyone you've been in contact with at the local garden centre.

 

Indonesia are still going on as normal, so we are screwed anyway....

You can see the six points of the contract tracing app here......

So for it to work all you need is.....

1) 40 million in the UK around 60% of the population to want to download it.
2) A phone with enough strength to download yet another app to it.
3) Internet access 24/7 so places would need free Wifi everywhere.
4) To trust people won't tell the app on their phone that they have symptoms when they don't, because if you come in to contact with them you have to self isolate.

 

But aren’t they themselves being tested ? This is how it’s been done in other countries they trace it and contain it .
Remember it’s relative to the whole community not just who one person had been in contact with.

 

It’s relative to the whole community your just concentrating on one individual .

 

You've completely lost me.

I go to work on my own in the car. I sit in an office on my own. I come home. Occasionally I go shopping. I get Covid-19. Tracking who I have been in contact with is relatively easy. No one at home. No one at work. The checkout woman at Asda. Right, let's test her.

Now. Let's look at that checkout woman. She's served 500 people just in the last two days. She's married, her husband is a police officer. Her kids are looked after by her parents while she's at work.

Can you see how it might be more difficult to track everyone she has served at Asda, everyone her husband has encountered, and her kids, and in turn everyone they have encountered, compared to tracking who I have encountered.

 

Because if I come into contact with more people it's harder to track and trace them all.

 

But the people at the check out are also being checked it’s a nationwide task , if it’s been tested nationwide at some point it is tracked , your saying one individual can’t say who they have been in contact with, no one can we pass people in the street etc .at some point the testing tracks it down it’s been proven in other countries .

 

That is mass testing not track and trace. They're different things.

One is as you say simply testing everyone in the country as often as possible to track the general spread of the disease.
The other which is what people were talking about is specifically tracking who an infected person has come into contact with in an effort to get them checked early and isolated as soon as possible.

Ie tracking and tracing contact rather than simply tracking the virus's general spread.

 

No it isnt because they are being tracked and tested .
It’s not a case that an individuals got it and try and get everyone they’ve been in contact with they test everyone and monitor it .
If it’s being contained then Barnsley hospital record a further outbreak they then concentrate testing and isolating again in that area . It’s happening in other countries it’s what the WHO are advocating . It’s not going away till they find a vaccine but it’s can be contained and monitored till they do .

 

That's not track and trace though, that's mass testing which is an equally valid approach but explains why people's replies to you have probably been a bit confusing

 

That's not track and trace, it's blanket testing.

We've tested half a million people so far. In all this time. Which means, of the UK population of 66 million+ we've still got 66 million to test, give or take.

 

Which is what I have been saying

 

Surely you have to blanket test to trace it though.
The original post I answered said it couldn’t be done .

 

They haven't really said anything except they don't know if contracting the virus builds immunity. You are right its worrying but all they have really said is "we don't know"
As I understand it viruses where you do build immunity doesn't 100% mean you can't catch it again. But if you do it's usually a lot milder. Again the truth is it's just too early to know anything for certain with this so the WHO are now advising a cautious approach.

 

They're different things. That's exactly why one can be done the other can't be done

 

The idea with track and trace is just to find the people the infected person has been in contact with. Presumably it will be people who have had a prolonged contact as they are more likely to have been infected.
The long incubation period is the real enemy of this approach.
