Did you know?
Cold sores are caused by the herpes simplex virus. A person will usually experience a tingling, itching or burning sensation around their mouth, before a sore appears. After initial infection, blisters and sores can reappear because the virus will always be present in the body and can be reactivated to cause reoccurrence of cold sores.
How to prevent:
People with active symptoms and a cold sore(s) should avoid oral contact with others and sharing objects that have contact with saliva.
