Repeat self-isolation

[soundsystem]

Sorry if this has been asked, but I haven't seen it if so (lots of threads).

I understand that if one family member has a new, continuous cough or a high temperature the whole family need to self-isolate.

So DC1 gets a cough. We all self-isolate for 14 days. Then if on day 15 DC2 has a temperature (say previously no-one had a temperature), then we all self-isolate for another 14 days, is that right?

I'm not being purposefully obtuse, I'm just trying to get my head round it!

(This is theoretical at present as we don't currently have symptoms. I just find it helpful to run through all possible situations before they happen (autism)).

I saw a chart about this.
I think the symptomatic person has to self isolate for longer.

But that logic only works assuming you all have the same bug

In my household we seem to have 2 or 3 on the go at any one time.

Chart is further down here

Yes, same here! I have a 5-year-old a 3-year-old and a baby so someone usually has something! Although I guess with the older ones not at school/pre-school and not coming into contact with anyone outside the family then they won't really be picking up new bugs!

Oh that chart is so helpful, thank you!

Another chart (hopefully legible!) that you may find helpful. The clock doesn’t reset to another 14 days each time a new family member becomes ill.

Does my niggle make sense though?
We started self isolation because ds1 had a bit of a cough.
He has had a bit of a cough or fever about every 10 days because he tends to be stressy and isn't very resilient.
So in a way, that's normal for him.

But currently we can't take chances from a public health perspective.

So say if his cough was from a common cold bug.

My daughter works in a university and interacts within a setting where people have tested positive for covid 19.
So she comes back from there on the bus (early as we realise ds1 has a cough and she needs to self isolate) and say it she contracts covid 19 surely it will take the full 14 days to work through us.

So in that scenario it seems like it would make sense to me that we would need to wait 7 days from the last person in the household beginning to show symptoms.

I'm autistic too and I quite like information to link up and make sense.
It's the one bit I struggle with.
