Cold sores: causes, symptoms and treatment

Cold sores are a common condition caused by the herpes simplex virus (HSV). Here are some key facts about the causes, symptoms and treatment of cold sores:

Causes

Cold sores are caused by the herpes simplex virus (HSV). The virus can be transmitted through direct contact with an infected person, by kissing, or by touching an infected area. A weakened immune system, stress, fatigue or exposure to sunlight can act as triggers.

Symptoms

The first signs of a cold sore are often a tingling or itching sensation on the lips. Small fluid-filled blisters then develop. These can be painful and eventually burst. The fluid is highly contagious, so you should avoid direct contact with others.

Treatment

There are various options for treating cold sores. Typically they resolve on their own within 10–14 days. To relieve symptoms you can apply a topical ointment containing acyclovir or penciclovir. Home remedies such as honey, tea tree oil or a cold compress can also help. In severe cases a physician may prescribe antiviral medication.

Prevention

There are several measures to reduce the spread of cold sores. Avoid close contact with infected persons. Do not share lip care products or eating utensils. Prevent sunburn on the lips by using sunscreen and apply lip balm as needed.

By understanding how cold sores develop and how they can be treated, you can take more effective measures to prevent their spread and relieve symptoms.
