Can herpes on the lips be transmitted and develop into shingles?

Cold sores are not contagious and do not develop into shingles. Cold sores are primarily a mucocutaneous disease caused by infection with herpes simplex virus, whereas shingles is an acute vesicular dermatitis caused by the varicella-zoster virus (VZV). These are two distinct viral infections and separate diseases; therefore, cold sores cannot transform into shingles. When cold sores occur, patients should apply acyclovir ointment topically under a physician's guidance and take antiviral medications as part of their treatment. Additionally, it is important to avoid consuming spicy or irritating foods and to develop healthy lifestyle habits to promote recovery. If symptoms persist or worsen, prompt medical attention is recommended.
