Have just been looking at NHS website, and seems that under 5s are not being swabbed under ‘test and trace’. I assume that means if any of those children get covid symptoms then they won’t be tested but the whole bubble/class has to isolate for 14 days instead. Whereas for symptoms in a 5 yr old case, the bubble would just isolate whilst awaiting result (assuming negative). Are any schools not taking back 4 yr olds? Otherwise, I can envisage YR returning and whole class isolating for 2 weeks all the time.
