//I would always tell anyone who I spend time with that there is a chance that I could have covid.//
Nothing wrong with that, Miss T. It's courtesy in the same way as you would tell them you might have 'flu or any one of a number of other infectious diseases. It's the testing I'm interested in. You began with this:
//...two of them have now tested positive...//
Why did they test for Covid? What's the purpose?
//Should this person concerned self isolate.//
Why? Somewhere in the order of 2m people are currently suspected of having Covid. What possible benefit will one person self-isolating have?
And then:
//...should you take a test now or wait and see if you have symptoms.//
Why test at all??
I'm not having a go at you. I simply fail to understand what this testing regime is achieving. How long do you aim to continue this regime? What do you want to see before you end it? I'm just completely bewildered by it.
// If I feel might have covidor if I know my wife as got it I will test sothatif I'm positive I know to be considerate if others and avoid close contact say with elderly relatives...its called being considerate//
So how long will you keep that up, bob? And what do you want to see before you end it? When your supply of tests (which were presumably provided when they were free) runs out, will you continue testing by buying them?
There is simply no logic to this routine testing.

What d'ya mean "at last"??? No, no, don't bother!! :-) :-)
