Definition: Cold sores, also known as herpes labialis, are small, painful blisters that form around the mouth. They are caused by the herpes simplex virus type 1 (HSV-1). After the initial infection, the virus remains dormant in the body and can reactivate under certain triggers, causing outbreaks of cold sores.
Causes: Cold sores are highly contagious and spread through direct contact with the virus, such as kissing or sharing utensils. Stress, sunburn, fever, and weakened immune system can trigger outbreaks.
Pros of Treatment: Treatment can shorten the duration and severity of outbreaks, but cannot cure the virus.
Cons of Treatment: Over-the-counter creams and antiviral medications can help, but may cause mild side effects.
Alternatives: There is no cure for herpes, but avoiding triggers and maintaining a healthy lifestyle may help reduce outbreaks.
Recovery Time: Cold sores typically heal within a week or two without treatment, but treatment can speed up healing.
Disclaimer: Cold sores are not the same as genital herpes. Consult a doctor for diagnosis and treatment.
