Cold Sore Fact Check: Do Cold Sores Mean You Have An STD?

Cold sores are caused by the HSV-1 virus, which is a strain of the herpes simplex virus. The herpes simplex virus has two strains: HSV-1, which causes oral herpes or cold sores, and HSV-2, which causes genital herpes.1,2 In general, HSV-1 is spread via oral-to-oral contact, but it may also cause genital herpes. HSV-2, which is categorized as a sexually transmitted disease, is spread via oral, vaginal and anal sexual contact.1,2,3 If you have a cold sore, then you have been infected with one of the herpes simplex viruses. However, having oral herpes is nothing to be ashamed of! The World Health Organization estimates that around 3.7 billion people around the world under the age of 50 have been infected with HSV-1.1

It’s important to understand the differences between the two strains of the herpes simplex virus. Below, we’ll walk through HSV-1 vs. HSV-2 and give some tips on how to live with oral herpes.

HSV-1 vs. HSV-2

As mentioned, the herpes simplex virus has two strains: HSV-1, which causes oral herpes, and HSV-2, which causes genital herpes.1,2 Both strains of herpes can cause blisters or ulcers that range in severity.1 When these blisters occur around the mouth, they’re called cold sores.2,4


HSV-1 causes oral herpes—also known as cold sores and fever blisters.4 The way that HSV-1 is spread is by engaging in intimate contact like kissing or oral sex with someone who is infected with HSV-1.4 After you become infected with HSV-1 for the first time, you carry the virus with you for the rest of your life.4 For some, the virus lies dormant and they never experience a cold sore outbreak, but others will experience symptoms from time to time.4

The best way to prevent getting infected with HSV-1 is not to engage in direct physical contact with someone currently experiencing HSV-1 symptoms.4 HSV-1 sores appear as fluid-filled blisters on and around the lips.4 The first time you’re infected with HSV-1 tends to be accompanied the most extreme symptoms, including swollen lymph nodes, headache and other flu-like symptoms.4 Subsequent flair ups are typically less severe.4


HSV-2 is the strain of the herpes simplex virus that causes genital herpes.1 The way that HSV-2 is transmitted from person to person is via contact with the anal or genital surfaces, skin, fluid or sores of a person that’s carrying the virus.1 It’s possible for HSV-2 to be transmitted even if there are no visible symptoms.2

Many people experience extremely mild or even no HSV-2 symptoms at all. In other cases, HSV-2 can cause small blisters on or near the genitals, rectum or mouth.3 Like oral herpes, the first genital herpes outbreak tends to have the most severe symptoms and may be accompanied by swollen lymph nodes, headache, fever, body aches and more viral shedding.3

To prevent spreading the HSV-2 virus, those that are infected should avoid having sexual contact with others while experiencing an outbreak.3 Using condoms correctly can also help limit the risk of spreading the virus, but full abstinence from sexual contact is the only way to guarantee that the virus is not transmitted.3
