Let's Talk About It: HSV-1 vs. HSV-2

Herpes Simplex Virus 

There are two strains of the herpes simplex virus, both of which can cause herpes infections, but they typically affect different areas of the body:

1. HSV-1

  • Commonly Causes: Oral Herpes, which results in cold sores or fever blisters around the mouth.
  • Transmission: Primarily through oral-to-oral contact, but it can also be transmitted through genital contact, leading to genital herpes.
  • Prevalence: More common than HSV-2 and is often contracted during childhood through non-sexual contact.
  • Symptoms: Blisters or sores around the mouth and lips, though it can also cause genital sores if transmitted to that area.

2. HSV-2

  • Commonly Causes: Genital herpes, which results in sores and blisters in the genital and anal areas.
  • Transmission: Primarily through sexual contact, including vaginal, anal and oral sex.
  • Prevalence: More commonly associated with genital infections and typically acquired during adulthood through sexual activity.
  • Symptoms: Painful blisters or sores in the genital or anal areas, sometimes accompanied by flu-like symptoms during initial outbreak. 

Key Differences:

  • Location of Infection: HSV-1 typically affects the mouth area, while HSV-2 usually affects the genital area.
  • Mode of Transmission: HSV-1 is often spread through non-sexual contact, whereas HSV-2 is primarily spread through sexual contact.
  • Prevalence and Age of Acquisition: HSV-1 is more common and often acquired in childhood, whereas HSV-2 is less common and usually acquired in adulthood.

Both HSV-1 and HSV-2 can cause similar symptoms when they infect the same area (oral or genital), and both can be managed with antiviral medications to reduce the frequency and severity of outbreaks. 

Here are some statistics on the prevalence of HSV-1 and HSV-2:

1. HSV-1: 

  • Approximately 67% of the global population under age 50 have HSV-1.
  • This equates to around 3.7 billion people worldwide.

2. HSV-2

  • About 13% of global population aged 15-49 have HSV-2/
  • This equates to around 491 million people worldwide.

These statistics highlight the widespread nature of both HSV-1 and HSV-2, with HSV-1 being far more common globally.

The importance is taking the proper safety precautions, and talking to your partners before engaging in sexual contact you can always book with me your favorite Sexologist or any other professional for help on how to communicate with someone if you are infected. It's not the end of the world having these infections, medicine has changed over the years and early detection is important!
