What can you do to prevent catching cold sores?
A doctor has provided 1 answer
Virus Infection: Cold sores are typically caused by virus infections that spread from person to person. Some viruses can live in the body and reactivate even if you haven't been re-exposed. If you have a history of cold sores, and they occur frequently, your doctor may be able to prescribe medication to suppress the virus from flaring.
