Having recently gone through the process it does seem very repetitive! However, you should engage with them. You don’t even have to talk to them. Just do the on line form (would have been sent to you via text, assuming you have your mobile number when you booked the test?)
They are aggressive in trying to contact you - but that’s because if they don’t get hold of a certain % of people, then the press and opposition (government) will give out stink. So yes, they need to get hold of as many people as possible.
Even though many won’t need to SI, it’s so they have the correct information from nhs directly. And they are then able to go and get a couple of PCRs.
The whole process does seem overboard though. After doing T&T for my Young DD, I then got a phone call to say ‘you’ve been identified as a contact’ .. er no shit Sherlock! I then got a call for my other DD saying the same (of course with her being a child I have to give my phone number as her number as she doesn’t have a phone herself). Lots of wasted resource. Also the call itself took 48 mins with me having to repeat the same things. It was painful to say the least.
When I did it for myself, I did it on line (much easier) and gave email address for those ‘I live with’ to save me getting the calls.
I have since had a call ‘asking how I am and so I intent to continue to SI’. Really don’t see the point of it. I’m hardly going to say ‘no I don’t’. They did thougb inform me under what circumstances I will have to continue SI after the 10 days. Which I did find useful. But they could have sent this info by text!
A lot of wasted money in the process. Whilst a t&t system is needed, it’s too repetitive! And too much money / resource being wasted!
