Are Cold Sores and Herpes the Same Thing?

No. Herpes can cause cold sores, but they are not the same thing. 

What Causes Cold Sores?

Cold sores are caused by the herpes virus, usually herpes simplex type 1 virus (HSV-1). The herpes simplex type 2 virus (HSV-2) typically causes genital herpes. However, either type can cause either cold sores or genital warts.

What Are Cold Sores?

Cold sores, which are caused by the herpes virus, are red, fluid-filled blisters that usually form around the mouth, although they may also appear on other areas of the face. Occasionally, cold sores may also show up on the nose, fingers or even the inside of the mouth.

Cold Sore Symptoms

The symptoms of cold sores are usually more severe the first time you have an outbreak and are milder during future outbreaks. Cold sore symptoms can include:

  • Tingling or burning that starts up to a few days before blisters form

  • A raised, red blister full of fluid that is tender and painful

  • Fever

  • Sore throat or pain when you swallow

  • Headache

  • Body aches or pains

  • Swollen lymph nodes

  • Nausea

What Are the Stages of a Cold Sore?

Cold sores go through 5 stages:

  • Stage 1: Itching and tingling about 24 hours before blisters show up

  • Stage 2: Fluid-filled blisters appear

  • Stage 3: The blisters ooze, burst, and become painful sores

  • Stage 4: Sores dry out and scab over, which leads to cracking and itching

  • Stage 5: The scab falls off and the cold sore is healed

How Do You Get Rid of a Cold Sore?

While there is no cure, and they usually go away on their own within a few weeks, cold sore treatment is available which can help shorten the length of time you need to deal with the cold sore. Here are a few ways you may be able to get rid of a cold sore faster:

  • Creams and ointments like penciclovir (Denavir) and docosanol (Abreva) are applied several times a day and can control pain and promote healing.

  • Oral antiviral medications like famciclovir (Famvir), valacyclovir (Valtrex), and acyclovir (Zovirax) are available by prescription only and can be useful in helping to treat and prevent frequent cold sore outbreaks.

  • Home remedies may provide some relief. Options include ice, lip balm with lemon extract, aloe vera gel, witch hazel, petroleum jelly, and lysine supplements.

Frequently Asked Questions

What Is the Difference Between Cold Sore vs Herpes?

Cold sores are a clinical sign of a herpes virus infection. Once you have the herpes virus, you have it for the rest of your life, and you may experience periodic cold sores. Outbreaks usually depend on your current health status. 

Does Everyone Get Cold Sores?

No, only people who are infected with the herpes virus get cold sores. However, according to the World Health Organization (WHO), approximately 3.7 billion people under the age of 50 – or 67% of the population – are infected with herpes simplex virus type 1 (HSV-1). That means as many as two out of every three people may get cold sores.

Do Cold Sores Mean You Have an STD?

While herpes is often transmitted through sexual activity, there are other ways to get the herpes virus. Sharing items like makeup, towels, or toothbrushes with somebody who is infected can cause you to get herpes and, as a result, start having cold sores.

Can You Get a Cold Sore Without Herpes?

No, cold sores are only caused by the herpes virus. 

How Long Does a Herpes Outbreak Usually Last?

Herpes outbreaks typically last around 20 days.

What Is the Difference Between Canker Sores and Cold Sores?

Is a canker sore the same as a cold sore? What’s the difference?

Cold sores are caused by the herpes virus and are usually found on the outside of the mouth. Canker sores are only found inside the mouth and have a variety of causes, including:

  • Injury to the inside of the mouth

  • Stress

  • Nutrient deficiencies

  • Hormone fluctuation

  • Use of toothpaste or mouthwash that contains sodium lauryl sulfate

  • Conditions that affect your immune system like lupus or inflammatory bowel disease

  • A reaction to certain foods like nuts, chocolate, or spicy foods

Canker sores are usually round or oval and white or yellow. They typically go away on their own within a week or two. For large or especially painful canker sores, or ones that don’t go away within a couple of weeks, talk to a doctor about treatment options.

How Long Are Cold Sores Contagious?

Anybody with the herpes virus can transmit it to another person whether or not they currently have cold sores. However, cold sores are the most contagious when the blisters are open and oozing.

How Do I Stop Getting Cold Sores?

If you get frequent cold sores, you may benefit from an oral antiviral medication like famciclovir (Famvir), valacyclovir (Valtrex), or acyclovir (Zovirax). These medications are available by prescription only, so talk to your doctor if you get more than a few cold sores every year.
