Herpes simplex infection (cold sore) is a viral infection that can occur on almost any part of the body. It typically starts with clear fluid-filled blisters, followed by the formation of crusted sores. There are two types of herpes simplex virus: Type 1, which usually causes outbreaks around the mouth and face, and Type 2, which primarily affects the genital area.

How Does Cold Sore Occur?

The virus causes the first outbreak when it enters the body. Afterward, it settles in the nerve roots and remains dormant. When certain conditions trigger it, the virus reactivates, leading to recurring outbreaks.

Where Do Cold Sores Appear?

Cold sores most commonly appear on the lips, around the mouth, nose, and chin. The blisters usually heal within 5-7 days as they dry up and form a scab.

How to Prevent Herpes Transmission?

Currently, there is no vaccine available to prevent the disease or its transmission. The most important method of prevention is avoiding contact with the infected area. It is crucial to avoid kissing and sharing personal items, such as towels, lip balms, or eating utensils.

How is Herpes Treated?

Treatment depends on the severity of the outbreak. Antiviral creams or systemic medications are used to treat the infection. It is important to start treatment within the first 1-2 days of the outbreak for maximum effectiveness. For individuals who experience frequent recurrences, suppressive therapy may be recommended for 6 months to 1 year.
