Has anyone heard of this (the subject title)? My child's nursery bubble burst on Friday and we got a message at the weekend stating they should self-isolate for 10 days. Today we got a message saying that there was a PHE directive requiring everyone from this bubble to isolate for one further day, taking the total isolation period to 11 days. I can't find anything online about this happening elsewhere. Why would it be? It does seem that the nursery has lots of cases at the moment and has had to close a lot of bubbles. But my other child, who is also now self-isolating because their bubble burst, has only had notice to self-isolate for 10 days. Very confused.
