What are cold sores? Cold sores, or herpes on the lips, is a skin infection that affects millions of people worldwide. It appears on the lips and perioral area in the form of painful blisters and is highly contagious. Cold sores are not curable, and the therapeutic approach involves managing the bothersome symptoms it causes. It is caused by an infection with type 1 of the HSV (Herpes Simplex Virus). HSV-1, which causes cold sores, can cause genital herpes if transmitted to the genitals. Genital herpes is caused by infection with type 2 of the HSV virus, and similarly, if transmitted to the lips, it can cause cold sores. Infection with the virus is one of the most common infections, as it is estimated that the majority of people under 50 years old carry the virus in their body. Genital Herpes Cold sores tend to reappear periodically and cause social anxiety to those affected.

Who do cold sores affect? It affects people of all ages. Exposure to the virus usually occurs in childhood, and from then on, the virus travels in the body until it finds the next opportunity to manifest. Most of us have been infected with the cold sore virus, and many also do not know they are carriers of the virus and can transmit it. The frequency with which cold sores, or herpes on the lips, appear varies from person to person. It may appear many times within a year or be limited to 1 or 2 episodes in an entire lifetime. Usually, over time, the number of cold sore episodes decreases.

Transmission Cold sores are highly contagious. They are usually transmitted through saliva and direct contact. Coldsores are mainly transmitted by: Direct skin-to-skin contact with the lesions. Sexual contact (oral). Kissing. Sharing glasses, forks, etc. Sharing lip cosmetics.

Why do cold sores appear? HSV-1 is the virus responsible for cold sores, while HSV-2 causes genital herpes. HSV-1 can also be transmitted to the genitals through oral sex, while less often, HSV-2 can conversely cause cold sores.

Symptoms of Cold Sores Cold sores manifest as one or more small, fluid-filled blisters on and around the lips, caused by the herpes simplex virus. They can also appear on other parts of the body, away from your mouth, if you touch a cold sore and then another area of your body. Typically, after about 48 hours, the blisters open, and after 10 to 15 days, they recede, and the lesion heals without leaving any marks. Cold sores often give warning signs one or two days before they appear. Symptoms can vary from person to person. However, at the site where the cold sore will emerge, you may experience: Tingling or numbness sensation Burning sensation Itching Swelling Lip pain The main symptom of the virus is the appearance of lesions on the lips. These lesions resemble small vesicles or blisters, contain fluid, and cause an intense burning sensation and itching. Sometimes, they may also be accompanied by nausea, headache, fever, or sore throat. After the skin infection subsides, the virus "deactivates" and remains in the body. Use over-the-counter medications for cold sores with early symptoms. They can reduce their duration.

Factors that "activate" cold sores Factors that can trigger the outbreak of cold sores include: Stress Fatigue An illness such as the flu or a common cold An injury to the area where the cold sore typically appears (e.g., a cut) Extreme temperatures Hormonal changes

Diagnosis of Cold Sores A dermatologist can diagnose cold sores through a clinical examination. If necessary, a sample from the lesion may also be taken for laboratory testing to confirm the diagnosis. In individuals with a compromised immune system, a sample is taken from the lesion for laboratory testing to determine the type of virus and the possible presence of antibodies in the body.

For the effective treatment of lesions, the timely initiation of therapeutic treatment plays a crucial role! (first 24 - 48 hours).

Cold sores or canker sores? Two medical conditions that resemble each other but are not the same thing are cold sores and canker sores (aphthous ulcers). Canker sores are small, painful lesions that develop inside the mouth, unlike cold sores, which develop on the surface of the lips. Their causes are not clear, but canker sores are not contagious or life-threatening.

Cold sores: Treatment & management For most patients, no special treatment is required. Since the virus cannot be permanently removed from the body, treatment aims to manage the lesions. For the treatment of herpes symptoms, your doctor will recommend a regimen: Either with antiviral medications applied topically (creams, ointments, etc.). Or systemic treatment with oral medications. Rarely, and in more severe cases where the above medications are not effective, intravenous therapy may be administered to alleviate symptoms. Additionally, if you frequently experience cold sores on your lips, you can ask your dermatologist to inform you about the possibility of preventive treatment against herpes. Nowadays, for aesthetic reasons, special patches, also known as patches, are often used, which are impregnated with antiviral medications!
