Class bubble isolating - separated parents

[Maggie9000]

My 8yr old son's teacher has confirmed covid so the class is now isolating for 14 days. Teacher has been absent from school since Friday.

Really struggling to find any guidance on whether DS can still go to his dads at the weekend (he last saw him Monday night/ Tuesday morning) so, hoping for advice/ opinions on three matters surrounding this:

Firstly: can DS still see his father? They last had contact on the morning before the email was sent regarding the confirmed case. Obviously they'd keep him home and he wouldn't have contact with anyone else just as he would here.

Secondly: my husbands daughter normally comes to us every weds and every other weekend, Is she is classed as another household rather than a sibling in this situation so can't mix with us until the 14 days is up? She attends a different school across town.

Third: I have lung disease, should I get my lad tested so I can prepare to get it?!

The child should do isolation in one house ideally. Not sure about your husband’s daughter, but I would not have her personally. With regards testing unless your son has symptoms he will not be offered a test.

@Mindymomo thank you

What Mindymomo said.

You shouldn't get your son tested unless he shows symptoms. Any negative test result you get by testing with no symptoms in the 14 day period from his last contact with his teacher is pointless because the virus could still be incubating/he could be yet to become infectious.

The guidance is unclear on this (there've been a few other threads about it, either in coronavirus or alone parents).

I take it that technically children can continue to move between their two homes no matter what, however you may decide that there's no point in increasing the number of people potentially exposed so it's not wise to do so while anyone's isolating.

None of the NHS or wider government guidance states that children have to stop moving between households if they are isolating.

I hope you are OK. Even if your son is infected, there is a less than 50:50 chance that he will infect you. Studies show that only about 30% of other household members catch Covid.

See this thread for example (although I don't think all the posters saying you must not move between houses are necessarily correct!)

DSD and DSS have to self isolate. Can they come to us? www.mumsnet.com/Talk/coronavirus/4051321-DSD-and-DSS-have-to-self-isolate-Can-they-come-to-us

Thanks @Augustbreeze that's really helpful

Agree guidance is not clear on this at all so I think you need to come to an arrangement with your son's father and step daughter's mother. Hopefully they will understand.
Chance are low that your son will get it so hopefully all will be well. No point getting him tested, in theory you could lie to get one but that would be pointless because even if negative he could turn positive the following day.
