Hand Foot Mouth. A rash in the mouth, hands and feet -- all at one time -- is due to infection with the coxsackie virus. Go see your pediatrician or family doctor to make sure of the cause.
By close contact. Several viruses can cause hand-foot-mouth disease, most often due to coxsackie virus. The infected person gets mouth sores and throat sores, plus spots on the palms and soles, and sometimes spots elsewhere. The spots don't break open (different from chicken pox or folliculitis, which do open). Mostly seen in kids, hfm disease can also infect teens and adults if they do not have immunity to it.
My son was diagnosed with hand foot mouth a 15 days ago. His symptoms were clearing up but since yesterday he has new blisters, did he get it again?
Possible. But more likely he has a different virus causing similar lesions.
