Herpes labialis (oral Herpes simplex)

Alternative names:

cold sore; fever blister; herpes simplex - oral

Prevention:

Avoid direct contact with cold sores or other herpes lesions. Minimize the risk of indirect spread by thoroughly washing items in hot (preferably boiling) water before re-use. Do not share items with an infected person, especially when herpes lesions are active. Avoid precipitating causes (especially sun exposure) if prone to oral herpes.
