Childhood Diseases and Illnesses

Herpes Simplex Type 1 (HSV1, Cold Sores)
  • Caused by a virus.
  • Symptoms include blister(s) around the mouth or face, pain, fever, fatigue.
  • Spread by contact with herpes virus in fluid from the blister(s) and saliva of carriers through kissing and/or spread to the genitals through oral sex. The virus can also be spread in the absence of symptoms.
  • Possibly contagious for five days but usually one to two days before onset of rash, and continuing until all blisters are crusted (about five days).
  • Most people will have had exposure by age five.
  • Between outbreaks, the virus persists in a resting state. Recurrent infections may be less severe than original outbreak and shorter in duration but are equally as contagious while symptoms persist.
Instructions for Schools
  • Discourage sharing of food, drinks, utensils, or anything that may transmit the virus.
