Definition
Cold sore is caused by Herpes virus
which is sexually transmitted. The first lesion may
have no symptoms. The lesions (vesicles, blisters,
open sores) may occur up to two weeks after contact
with someone who has the virus. The virus may become
latent and live in the nerve cells to return at any
time, causing
Cold Sores
in or near the same locale. This occurs whenever the
body is under stress (from illness, physical or
emotional stress).
