Cold Sores (Fever Blisters): What You Should Know

Cold sores, often called fever blisters, are caused by the herpes simplex virus type 1 (HSV-1). While generally not dangerous, they are contagious, uncomfortable, and tend to recur after your first outbreak. That’s because the virus stays in your body permanently—it lies dormant in nerve cells and can reactivate due to various triggers.

🧬 What Causes Cold Sores?

Most people contract HSV-1 in childhood, usually through simple contact—like sharing eating utensils, towels, or a kiss. After the first infection, the virus goes quiet but never completely leaves. It hides within the body until something sets it off again.

HSV-1 is most commonly linked to cold sores around the mouth, while HSV-2 is usually associated with genital herpes. However, either type can affect different body parts, depending on how the virus is transmitted.

⚡ What Can Trigger an Outbreak?

Even when dormant, certain circumstances can activate the virus and cause cold sores to reappear:

• Physical or emotional stress
• Colds, fevers, or other illnesses
• Reduced immune system function
• Hormonal fluctuations (e.g., menstruation)
• Excess sun exposure, especially on lips
• Lack of rest or poor sleep

Cold sores typically show up on the lips, near the nose, on the chin, or around the cheeks.

👄 How to Spot the First Signs

Before cold sores fully form, the body often gives early hints:

• Tingling, itching, or burning around the lips
• Slight redness or puffiness
• Within 1–2 days: tiny blisters appear, break open, and scab over

They usually heal within 2 to 4 weeks. Catching it early can help ease symptoms and shorten the duration.
