■ Herpes Simplex Virus: Infection of the skin with HSV results in vesicular eruption. Viruses traverse cutaneous nerves and lie dormant in paraspinous ganglia until reactivated to produce recurrent disease.
■ Herpes Varicella Zoster: Respiratory infection with HV virus subsequently spreads to involve the skin. Reactivation of dormant viruses produces localized HZ infection.
■ HFM: Infection of the oropharynx or gastrointestinal tract with coxsackievirus A-16 or enterovirus 71 results in a viremia that spreads to many organs, including the skin and oral mucosa.
