What (if anything) should we do?

[NaToth]

I get so confused by the rules.

DSIL was exposed to COVID on a boys' weekend 9 - 11 July. He was longed and then had to isolate until 21 July. I don't know whether he tested.
Toddler DGC got ill on 19 July, so while his DF was still isolating with a temperature, not eating, very cranky, not sleeping, more frequent dirty nappies. DGC has not been tested.

We didn't know any of the background until we'd spent most of the day with them and been in close contact with DGC to give DD a break. We left as soon as we knew and haven't been in contact with anyone else since.

I don't think DD and her DH have handled this well, but what should we do now? Do we test, do we isolate or do we just hope it's a cold and carry on as normal?

He was pinged. Damn you Autocorrect!

Not clear what's happened here but if you saw him within the self-isolation period he wasn't self-isolating, was he?
Do you have any symptoms?

I think it’s rare anyone go on to test positive after being pinged. I wouldn’t isolate if they’ve not been tested unless you become symptomatic x

So, Son-in-law didn't respect his isolation and as far as you know hasn't tested? The child has Covid symptoms? You've had contact with them during the non-isolation?
I'd test for my own peace of mind but presumably you are vaccinated?

From the day your grandson developed symptoms, whether or not he tested, the whole family should have begun isolating.

If the test were to be negative, the isolation stops, except for son in law, who needs to complete his isolation.

Whether you believe these rules to be right or wrong, these are currently the legal requirements in England (you don't say where you are).

As it stands, if the baby is not tested, the family should be in isolation until 29/30 July - 10 full days.

Two weeks later, nobody will have to isolate except the baby.

As for you. Legally you don't have to isolate as you were not in contact with a confirmed positive case. Situation alters if toddler tests positive.

But you may wish to reduce contacts until the end if the month.

That's really helpful, thanks.

You seem very calm, I’d be fuming! This is how it spreads so quickly when people don’t test and isolate when someone’s symptomatic.

I’d get some lateral flow tests and do them randomly for a little while. Maybe stay clear of meeting people indoors.

I stuck to the facts I'm actually pretty cross about it, but a ranty post achieves nothing.
