My 3 year old is on day 5 of chicken pox and although his appetite returned today, some of the spots around his neck look a bit dodgy - so I wasn't sure if they were infected? He has a particularly bad case of chicken pox and is pretty much covered in spots, but how do I tell if they're infected? He still has a high temperature, although not as high as it has been over the past few days. I've attached a picture of the dodgy looking spots on his neck and head.
