To prevent transmission, patients should wash their hands regularly and avoid going to school until the ulcers have healed and the rashes have dried up. Patients often eat and drink less due to the painful mouth ulcers, hence it is important to monitor for dehydration and encourage food and water intake.

  • Stomatitis
  • Mucous membrane pemphigoid
  • Acute tonsillitis / pharyngitis
  • Shingles

Related serious diseases
