According to the BBC anyone in England who tests positive for coronavirus will be contacted via text, email or over the phone and asked to log on to the NHS Test and Trace website, where they'll be asked for details of people with whom they've been in close contact.
Under-18s will be phoned, and a parent or guardian will need to give permission for the call to continue.
The tracers can track down the contacts of 10,000 people every day, the government says.
This could include household members, but extends to anyone they have been within 2m (6ft) of for more than 15 minutes.
so let’s say I get the symptoms but don’t report - useless
I do report, get asked to log on to the website but don’t - useless
I do report, get tested and contacted and asked who I have been in contact with. Half I can’t remember and no way am I telling them about my mistress/sex worker/drug dealer/whatever. - useless
They ask for permission to talk to under 18s in my household who are covid positive. I refuse. - useless
Been on a train for over 15 minutes no idea who else was - useless
Been on a tram for over 15 minutes no idea who else was - useless
Been in a cab for over 15 minutes no idea who was in it before me infecting every surface - useless
That’s before they start telling my contacts they have to take sick leave!
