Herpes labialis
Herpes Labialis
Herpes labialis, commonly known as cold sores, is a type of infection by the herpes simplex virus that primarily affects the lip. Symptoms typically include a burning pain followed by small blisters or sores. The first attack may also be accompanied by fever, sore throat, and swollen lymph nodes. The rash usually heals within 10 to 14 days, but the virus remains dormant in the trigeminal ganglion. The virus may periodically reactivate to create another outbreak of sores in the mouth or lip.
Pronunciation: /ˈhɜːrpiːz ləˈbaɪəlɪs/
Etymology: The term "herpes labialis" is derived from the Greek word "herpein" meaning "to creep", referring to the spreading nature of the sores, and "labialis" from the Latin "labium" meaning "lip".
Causes
Herpes labialis is primarily caused by Herpes simplex virus type 1 (HSV-1). It can also be caused by Herpes simplex virus type 2 (HSV-2), but this type is less common. The virus is spread between people by close personal contact, such as kissing. The virus can also spread to the fingers or eyes, or other parts of the body.
Treatment
Treatment includes antiviral medication, such as acyclovir, valacyclovir, or famciclovir. These medications can reduce symptoms, but they do not cure the infection. Over-the-counter treatments, such as docosanol, can also be used to reduce symptoms.
Prevention
Prevention methods include avoiding close contact with infected individuals, especially when they have an outbreak. Using sunblock can help prevent outbreaks triggered by sun exposure.
