Herpes labialis, also known as cold sores or fever blisters, is a viral infection caused by the herpes simplex virus type 1 (HSV-1). It typically affects the lips, but can also occur on the gums, tongue, or inside of the cheeks.
Symptoms of herpes labialis include small, painful, fluid-filled blisters or sores that appear on or around the lips. The blisters may be preceded by a tingling or burning sensation in the affected area. The blisters usually crust over and heal within a few weeks.
Herpes labialis is highly contagious and can be spread through direct contact with an infected person, or through contact with an object or surface that has come into contact with the virus.
There is no cure for herpes labialis, but antiviral medications can help to reduce the severity and duration of symptoms. Over-the-counter creams and ointments may also help to relieve pain and promote healing.
To prevent the spread of herpes labialis, it is important to avoid close contact with people who have active infections, and to avoid sharing personal items such as towels, razors, or utensils.
If you suspect that you may have herpes labialis, it is important to seek medical attention for proper diagnosis and treatment. In some cases, herpes labialis may be mistaken for other conditions, such as canker sores or impetigo, and may require different treatment approaches.
