Me and my husband are both key workers & so our baby has been going to nursery as normal 2 days a week. We had an email from the nursery today to say that a child in our babies bubble had a positive covid test yesterday. The nursery are insisting that only people who had contact with the positive case 48 hours before their test need to isolate and therefore the bubble remains open and all staff and children are safe to be in nursery as normal as the positive case has not effected anyone directly due to this 48 hr clearance - However I can not get my head around this rule as we are told the virus has a 10-14 day incubation period. Can someone please explain and put my mind at ease that this is correct and we are not at risk from this case or carrying on as normal. I totally understand its a risk sending them to nursery at the moment & not at all annoyed that some one else had tested positive in fact i am genuinely concerned for the family and wish them well. My concern is that we are being given correct information about contact and isolation. Sorry to write an essay. Thank you
