L'herpès labial est une infection causée par le virus de l'herpès simplex, caractérisé par une éruption de petites cloques habituellement douloureuses sur les lèvres, la bouche ou la peau autour de la bouche. Ces cloques sont communément appelées boutons de fièvre ou boutons de fièvre.
Vue d'ensemble, causes et facteurs de risque
Herpes labialis is an extremely common disease caused by infection of the mouth area with the herpes simplex virus, most often type 1. Most Americans are infected with the type 1 virus by the age of 20.
- Types de virus de l'herpès humain
- HHV 1 – Herpes Simplex Virus 1 (HSV 1)
- HHV 2 – Herpes Simplex Virus 2 (HSV 2)
- Hhv 3 -virus zoster virus (vzv)
- HHV 4 – Ebstein Barr Virus (EBV)
- HHV 5 – Cytomegolovirus (CMV)
- HHV 6 – Human B-cell Lymphotrophic
- HHV 7 – Causes & Symptoms Similar to the HHV-6
- HHV 8 – It is a Type of Rhadinovirus
The initial infection may cause no symptoms or mouth ulcers. The virus remains in the nerve tissue of the face. In some people, the virus reactivates and produces recurrent cold sores that are usually in the same area, but is not serious. Herpes virus type 2 usually causes genital herpes and infection of babies at birth but can also cause herpes labialis.
Herpes viruses are contagious. Contact can occur directly, or through contact with infected razors, towels, dishes, etc. Occasionally, oral/genital contact can spread oral herpes to the genitals (and vice versa), so people with active herpes lesions on or around their mouths or on their genitals should avoid oral intercourse.
The first symptoms usually appear within 1 or 2 weeks, and as late as 3 weeks, after contact with an infected person. The lesions of herpes labialis usually last for 7 to 10 days, after which, then begin to resolve. The virus may become latent, residing in the nerve cells, with recurrence at or near the original site.
Recurrence is usually milder. It may be triggered by menstruation, sun exposure, illness with fever, stress, or other unknown causes.
Symptômes et signes
Des symptômes d’alerte tels que démangeaisons, sensation de brûlure, sensibilité accrue ou sensation de picotement peuvent survenir environ 2 jours avant l’apparition des lésions.
- Lésions cutanées / éruptions cutanées situées autour des lèvres, de la bouche et des gencives
- Small blisters (vesicles), filled with clear yellowish fluid blisters appear on a raised, red, painful skin area.
- Blisters form, break, and ooze yellow crusts slough to reveal pink, healing skin.
- Several smaller blisters may merge to form a larger blister.
- Mild fever (may occur).
La prévention
Avoid direct contact with cold sores or other herpes lesions. Minimize the risk of indirect spread by thoroughly washing infected items in hot (preferably boiling) water before re-use. Do not share items with an infected person, especially when herpes lesions are active. Avoid precipitating causes (especially sun exposure) if prone to oral herpes.
Avoid performing oral intercourse when you have active herpes lesions on or near your mouth and avoid passive oral intercourse with someone who has active oral or genital herpes lesions. Condoms can help reduce, but do not entirely eliminate, the risk of transmission via oral or genital intercourse with an infected person.
Unfortunately, both oral and genital herpes viruses can sometimes be transmitted even when the person does not have active lesions.
Diagnostic & Tests
Le diagnostic est établi sur la base de l'apparition et / ou de la culture du fluide ou des frottements de la lésion. L'examen peut également montrer un élargissement des ganglions lymphatiques dans le cou ou l'aine.
Traitement
Untreated, the symptoms will generally subside in 1 to 2 weeks. Antiviral medications along with analgesics may be given by mouth to shorten the course of the symptoms and decrease pain.
Washing the blisters gently with soap and water helps to minimize the spread of the virus to other areas of skin. An antiseptic soap may be recommended. Applying ice or warmth to the area may reduce pain.
Take precautions to avoid infecting others (see Prevention).
The Prognosis (Expectations)
L’herpès labial disparaît généralement spontanément entre 1 et 2 semaines. Cela peut se reproduire. L'infection peut être grave et dangereuse si elle se produit dans ou près de l'œil, ou chez des personnes immunodéprimées ou immunodéprimées.
Complications
- Spread of herpes to other skin areas.
- Secondary bacterial skin infections.
- Recurrence of herpes labialis.
- Generalized infection may be life-threatening in immunosuppressed people, including those with atopic dermatitis, cancer, HIV infections.
- Blindness.
