Hand, foot and mouth syndrome (or disease to all you lay people out there) is a common viral illness, most often caused by coxsackie virus. Generally it affects daycare-aged children (the 1-10ish age group), mostly under the age of 6. The big thing is the fever with a rash on, you guessed it, the palms, soles and in the mouth. Sometimes the rash can also present on the trunk or back as well. The worst part is that the vesicles in the mouth are VERY painful, so it’s not uncommon for kids to want to stop eating or drinking when they have it.
