We can't actually get a PCR test for her. We do have 2 rapid tests left - and used one to get a negative result on Sunday (when we first heard her cough and we wanted to be safe in leaving the house), but is it worth trying again?
The same document tells us that if you're not eligible for testing, then "if you have any of the symptoms listed below, the individual is presumed to have COVID-19 infection and is advised to self-isolate." And yes, the little has had a few symptoms: a nasty cough, some chills, a runny nose, extra fatigue, and even some shortness of breath a few days ago. Even if it's not covid, whatever she has is unpleasant and shouldn't be passed on to others. (Matthijs and I thankfully haven't gotten what she has).
As for how much it matters - well, there are now new regulations for isolation: "If the individual is fully vaccinated OR is a child under the age of 12 years old, they should self-isolate for at least 5 days from symptom onset AND until their symptoms have been improving for 24 hours, whichever is longer in duration." Unfortunately, we didn't realize we all should have started isolating sooner - because we're still adjusting to the new rules - but tomorrow will be day 5. On top of that, our one housemate is mostly managing the inconvenience of staying out of contact with us (and the other has yet to return), and the little is slowly getting better. She's well enough now to enjoy being sick and so she fake coughs every time we ask her if she's getting better - so that she can avoid school and stay in her pyjamas all day.
So I presume everything is okay and we're doing the best we can with the information we have - but I think I'd still like to know. Perhaps because I have a lingering sense of getting covid as being connected to some moral failure (even though I know that's wrong). Or perhaps simply because I'm tired of trying to make the best decisions when I don't feel like I know enough.
