M will show up literally only on the
hands, feet and inside the mouth. My son had it around the outside of his mouth, on his
hands, not as much on his feet, but also on his arms and in the diaper area which is not usual. He ran a high fever (105 at one point) off and on, had this crazy rash and was very miserable..screaming all night for 2 nights in a row. This is because it often can make their joints ache. Good news is, it is very very rarely serious and they recover fairly quickly.
