Dream About Infectious Illness Spreading

I have had this dream twice now. It starts in an odd looking place that looks like a big cathederal mixed with some kind of nursery, it looks fancy and beautiful. Me and another woman are looking after a group of 7 children, and one of them starts to get ill. We noticed this and began to worry because for some reason we both remembered this "happening before". Eventually this child starts to bite and misbehave and other kids start to get ill too, so it's spreading fast. Now there are 2 ill children who are misbehaving, we warn staff members and i go and ask the sensory room manager if we can use the sensory room to isolate the children but she says no, by the time I am back almost all of the children are ill. Then we turn the tv news on and it is a worldwide spread of an infectious illness. I look down at my arms and stomach and realise i am covered in tiny spots in an odd pattern, they are the size of little needle holes in my skin but there are millions of them all packed together and in and odd tiger print pattern all across my body. The children are laughing and misbehaving while we try and isolate them and keep them contained, one of them passes away this is symbolised as them falling asleep in my dream. I remember from the last time I had this dream that all the children and only the children who are infected pass away and everyone else is ok.
