Coxackievirus
Hand, foot, and mouth disease is usually characterized by tiny blisters on the inside of the mouth and the palms of the hands, fingers, and soles of the feet. It is commonly caused by coxsackievirus A16 (an enterovirus), and less often by other types of viruses.
Coxsackievirus syndrome, causes painful red blisters in the throat and on the tongue, gums, hard palate, inside of the cheeks, and the palms of hands and soles of the feet. Herpangina, an infection of the throat which causes red-ringed blisters and ulcers on the tonsils and soft palate, the fleshy back portion of the roof of the mouth.
