How Common Is Herpes? Statistics That Might Surprise You

The Numbers Most People Do Not Know

If you have been diagnosed with herpes and feel like you are in a tiny, stigmatized minority, the actual statistics may change your perspective significantly. Herpes is not rare. It is one of the most common viral infections in the world, and the gap between how common it is and how stigmatized it is may be one of the biggest disconnects in public health.

Global HSV-1 Prevalence

According to the World Health Organization, an estimated 3.8 billion people under the age of 50, or 64 percent of the global population in that age group, had HSV-1 infection in 2020, the latest available estimates.

The WHO estimates that around 10 percent of those HSV-1 infections, about 376 million, were genital infections in people aged 15 to 49.

Most HSV-1 infections are acquired during childhood, and the WHO notes that most herpes infections cause no symptoms or go unrecognized. Many people with HSV-1 are unaware they carry the virus.

Global HSV-2 Prevalence

The WHO estimates that 520 million people aged 15 to 49 had HSV-2 infection in 2020, about 13 percent of the world population in that age range. An estimated 205 million people aged 15 to 49 had at least one symptomatic episode of genital herpes that year.

HSV-2 infects women almost twice as often as men, according to the WHO, because sexual transmission is more efficient from men to women. In the United States in 2015 to 2016, age-adjusted HSV-2 prevalence was 15.9 percent among females and 8.2 percent among males aged 14 to 49.

These estimates come from blood-test surveys, which is why they include the many people who have never been diagnosed. CDC notes that the majority of people with HSV-2 have not had the condition diagnosed.

United States Prevalence

In the United States, the CDC estimates that approximately 47.8% of people aged 14 to 49 have HSV-1 and approximately 11.9% have HSV-2, based on National Health and Nutrition Examination Survey (NHANES) data.

Put another way, nearly half of Americans in that age range have HSV-1, and about 1 in 8 has HSV-2. The National Center for Health Statistics also found that the prevalence of both types fell between 1999 to 2000 and 2015 to 2016. Most people with HSV are undiagnosed, in part because routine STI screening does not include herpes blood tests.

In a room of 10 Americans aged 14 to 49, you would statistically expect about five to have HSV-1 and at least one to have HSV-2. Most of them do not know it.

Why the Stigma Is So Disproportionate

Herpes became heavily stigmatized in the late 1970s and early 1980s, when magazines and TV ran alarmed coverage of a genital herpes "epidemic." In 1982, Time put herpes on its cover as "Today's Scarlet Letter." A popular theory says drug marketing created the stigma, but a 2019 Slate investigation found little support for it: the panic was already under way before the first antiviral for genital herpes was approved in 1982, and the drug maker's later ads stressed that herpes is controllable.

Before that era, genital herpes drew far less alarm. In the early 1970s, some doctors and advice columnists still described it as a common infection that was barely a disease. The medical reality of herpes has not changed. The cultural perception has.

Today, health organizations describe herpes as common and manageable. Planned Parenthood notes that it usually does not lead to serious health problems. Rare complications do exist, such as neonatal herpes, and HSV-2 raises the risk of acquiring HIV, which is why medical care still matters. None of this defines a person's character, worth, or dateability.

What These Numbers Mean for You

If you have herpes, you are not in a small, isolated group. You are part of a global majority of people under 50 (for HSV-1) or a very large minority (for HSV-2). The person sitting next to you at work, at the gym, or on the bus may very well carry the same virus.

These statistics do not make the emotional impact of a diagnosis disappear. But they can help put it in perspective. You are not alone, you are not damaged, and the right person will not care about a virus that most people under 50 carry in one form or another.
