I'm not sure about interstates but 'slap cheek' (parvo virus) is going around as well at the moment up here. Alot of the "symptoms" are not dissimilar to that of a flu/cold (ie. temps, runny nose, cough, irritability etc) but of course it's the rash that arrives (after they've stopped being contagious typically - so many children get sent to daycare/childcare whilst their contagious because they're parents don't know they're going to pass it on) a few days later.... my niece & her cousin have just had it courtesy of a few kids at childcare.

The rash looks a bit like a heat rash at times, first thing in the morning it looked like she had 2nd degree burns on her chest & arms. Oh, and the rash can rotate for want of a better word. It might show on the thighs in the morning, but then have moved to the arms and chest in the afternoon and then is just on the face in the evening.
