How common is herpes in Texas? It’s a question many people search after an HSV diagnosis, often with the feeling that they’ve suddenly become part of a very small group. The numbers suggest something very different. HSV is far more widespread than most people realize, and because many infections are never diagnosed or reported, official figures likely capture only part of the picture.
This guide brings together the most reliable data currently available for Texas — including national HSV prevalence studies, county-level STI trends, demographic patterns, and the factors that make estimating real-world HSV rates difficult. Looking at the data doesn’t change a diagnosis, but it can provide something many people need afterward: perspective.
How Common Is Herpes in Texas? Starting With the National Baseline
Before the Texas picture can make sense, you need the national foundation it sits on.
HSV-1: The virus most people already carry
According to the CDC’s NCHS Data Brief No.304 on herpes prevalence, approximately 47.8% of Americans aged 14 to 49 carry HSV-1. That’s close to one in two adults. Most acquired it in childhood through casual oral contact — a kiss from a relative, shared utensils — and many have never had a noticeable symptom. HSV-1 has become so normalized in its oral form that most people don’t think of it as an STI at all, even though it can and does appear genitally through oral sex.
In a state of 31 million people, applying that national figure means somewhere in the range of 14 to 15 million Texans are carrying HSV-1 at any given time. Most of them have no idea.
HSV-2: More prevalent than people realize
HSV-2 — the strain more commonly associated with genital herpes — affects approximately 12% of Americans aged 14 to 49, or roughly 1 in 8 adults in that age group. The CDC estimates there were 572,000 new genital herpes infections in the United States in 2018 alone, representing ongoing transmission at scale across the country.
Applied to Texas’s adult population, that 12% figure translates to a conservative estimate of over 2.5 million Texans in the 14–49 age range carrying HSV-2 — and the vast majority of them have never been formally diagnosed.
The 90% problem
Perhaps the most striking statistic in the entire HSV landscape: approximately 90% of people who carry HSV-2 are unaware of their infection. The virus is frequently asymptomatic, standard STI testing panels don’t include HSV blood tests by default, and many people who do have symptoms attribute them to something else entirely.
This is why how common is herpes in Texas is such a difficult question to answer with precision — not because the data doesn’t exist, but because most transmission happens between people who have no idea they’re infected. The real prevalence is almost certainly higher than any estimate can capture.For specific differences between HSV-1 and HSV-2, please refer to our article: “HSV-1 vs HSV-2 Dating: What You Need to Know.”
HSV-1 vs. HSV-2: Statistical Breakdown at a Glance
| Virus Strain | National Prevalence(U.S. Adults Aged 14–49) | Estimated Texas Cases(Out of 31M Population) | Transmission & Key Characteristics |
HSV-1
(Oral / Genital) | ~47.8%
(Nearly 1 in 2 adults) | 14 Million – 15 Million | Primarily acquired during childhood via non-sexual contact (sharing utensils, kisses from relatives). Frequently causes cold sores, but is now a leading cause of new genital infections via oral sex. |
HSV-2
(Genital) | ~12.0%
(Roughly 1 in 8 adults) | Over 2.5 Million | Almost exclusively sexually transmitted and primarily associated with genital herpes. Notably, ~90% of carriers remain completely undiagnosed due to absent or minor symptoms. |
How Common Is Herpes in Texas at the County Level?
Why Texas doesn’t track HSV directly
Here’s something that surprises most people: herpes simplex virus is not a reportable condition in Texas. Unlike chlamydia, gonorrhea, syphilis, and HIV — which must be reported to the Texas Department of State Health Services — HSV cases are not required to be logged, counted, or tracked at any level of the state public health system.
The Texas DSHS 2022 STD Surveillance Report covers chlamydia, gonorrhea, syphilis, and HIV in extensive county-by-county detail. HSV appears nowhere in it. That’s not an oversight — it reflects the deliberate decision by Texas and federal public health authorities to exclude HSV from mandatory surveillance, partly because of the high rate of asymptomatic infection and the complexity of blood-based diagnosis.
The practical consequence: there is no official Texas HSV case count. What we have instead are national seroprevalence studies that can be applied to state populations, and broader STI data that gives us a meaningful picture of the sexual health landscape in which HSV circulates.
What broader STI data tells us about Texas counties
A 2025 report based on CDC data ranked U.S. counties by overall STI rates — and three Texas counties landed in the national top 20 for large counties:
- Dallas County: No. 7 nationally, with 1,314.5 STI cases per 100,000 residents
- Travis County (Austin): No. 14, with 1,160.3 cases per 100,000 residents
- Harris County (Houston): No. 17, with 1,041.4 cases per 100,000 residents
These figures cover reportable bacterial STIs — chlamydia, gonorrhea, and syphilis — not HSV specifically. But STI rates across different infections in the same population tend to move together, driven by the same underlying factors: population density, healthcare access, income disparities, and the size of sexually active networks. High reportable STI rates in these counties are a reliable indicator of significant HSV prevalence as well.
Texas overall ranked 19th nationally — a mid-range position that obscures the significantly elevated rates in its major metros.
City-by-city snapshot
Dallas leads Texas’s major counties in STI rates and sits 7th nationally. Dallas County’s ranking reflects significant disparities in income and healthcare access across its neighborhoods, with younger residents aged 15–29 accounting for a disproportionate share of new infections. For a full local guide, see Finding HSV Singles in Dallas.
Houston (Harris County) ranks 17th nationally, with STI rates consistently above the Texas state average across all reportable infections from 2016 through 2022, according to Harris County Public Health. The county’s population of 4.7 million means the absolute number of people carrying HSV is substantial — conservative estimates suggest well over 400,000 Harris County residents carry HSV-2. More on Houston’s specific picture in HSV Dating in Houston, Texas.
Austin (Travis County) comes in 14th nationally despite its reputation as a progressive, health-conscious city. Austin’s high STI rate partly reflects a younger, more mobile population — driven by university students and tech-sector in-migration — and also partly reflects higher testing rates. More testing means more diagnoses, which means higher reported numbers even if actual prevalence isn’t necessarily the highest.
San Antonio (Bexar County) has historically carried elevated STI rates tied in part to its large military population. Lackland Air Force Base and Fort Sam Houston bring significant numbers of young adults to the area, and military populations have documented higher rates of STI exposure than the general public.
How Common Is Herpes in Texas Across Different Demographics?
HSV doesn’t distribute evenly across the population. Understanding who’s most affected matters — both for accurate risk awareness and for understanding the broader public health context.
Age
Nationally, nearly half of all STI cases — 48.2% in 2023, according to the CDC’s STI Surveillance Report — occur among people aged 15 to 24. In Texas, Healthy Futures of Texas data shows that 15-to-24-year-olds account for nearly half of gonorrhea cases statewide, with similar patterns across other STIs.
For HSV specifically, initial infection is most common in young adults, but because the virus is lifelong, its cumulative prevalence increases with age. People in their 30s and 40s are statistically more likely to carry HSV than teenagers — not because they’re more exposed now, but because they’ve had more years of exposure across their lifetime.
Gender
The Office on Women’s Health estimates that approximately 1 in 5 women aged 14 to 49 carries HSV-2, compared to approximately 1 in 10 men in the same age range. The disparity exists because of anatomical differences — the virus transmits more efficiently from male to female partners than the reverse. Women in Texas face HSV risk consistent with or potentially higher than national averages, given the state’s historically lower rates of healthcare coverage and preventive care access for women in lower-income counties.
Race and ethnicity
CDC data shows significant disparities in HSV-2 prevalence by race and ethnicity. Among non-Hispanic Black adults aged 14 to 49, HSV-2 prevalence has been documented at 34.6% — compared to 8.1% among non-Hispanic white adults. These disparities reflect systemic inequities in healthcare access, historical discrimination in medical systems, and structural factors that shape sexual health outcomes, not any inherent biological differences.
Texas has a large non-Hispanic Black population, particularly concentrated in Dallas, Houston, and their surrounding counties. The state also has a substantial Hispanic population, for whom HSV-2 rates fall between those of non-Hispanic white and Black populations nationally. Understanding these disparities matters for public health — and for any honest assessment of how common is herpes in Texas across communities.

What We Notice Across Texas HSV Communities
What We Notice Across Texas HSV Communities
Numbers tell one part of the story. Community experiences often reveal another. While individual situations differ, several recurring themes appear across HSV support spaces and dating communities throughout Texas.
Many people say the diagnosis initially felt more overwhelming emotionally than physically. For a large percentage of people, outbreaks eventually become manageable, while concerns about dating, disclosure, and stigma tend to last much longer.
Another pattern is that many people assume they’re statistically isolated until they begin seeing prevalence data. It’s common for people to believe they know nobody else with HSV, only to later realize that many infections are never diagnosed or openly discussed.
Large metro areas such as Houston, Dallas, Austin, and San Antonio can also create a different experience compared with smaller towns. Bigger populations often mean larger social networks, more healthcare resources, more support communities, and more opportunities to meet people who already understand HSV.
A final pattern appears repeatedly: people often expect disclosure conversations to go worse than they actually do. Fear before the conversation is frequently stronger than the reaction afterward. Once prevalence data becomes easier to understand, that fear often starts to feel more proportional to reality.
What the Numbers Mean If You’re Dating in Texas
Statistics don’t date anyone. People do. But the numbers do change how you should think about your situation.
If you have HSV and you’re dating in Houston, Dallas, Austin, or San Antonio, here’s what the data implies: a meaningful proportion of the people you’re meeting are also carrying some form of HSV — most of them without knowing it. You’re not disclosing something that makes you a statistical outlier. You’re disclosing something that puts you in the company of a very large, very quiet majority.
The American Sexual Health Association consistently notes that disclosure, when handled with calm honesty and accurate information, results in acceptance far more often than people expect. That finding makes more sense when you understand the prevalence numbers — many of the people you’ll date have their own HSV story, even if they’ve never had reason to tell it.
For practical guidance on the disclosure conversation itself, our guide on telling a new partner you have HSV covers the ground in full. And if you’re still working through the emotional weight of the diagnosis, does having HSV mean your love life is over? addresses that directly.
Frequently Asked Questions
How common is herpes in Texas specifically?
There’s no official Texas-specific HSV count because HSV is not a reportable condition under Texas law. Applying CDC national seroprevalence rates to Texas’s population of 31 million suggests over 2.5 million Texans in the 14–49 age range carry HSV-2, with an additional estimated 14–15 million carrying HSV-1. These are estimates, not official figures.
Which Texas county has the highest STI rates?
Among large counties, Dallas County ranks No. 7 nationally with 1,314.5 STI cases per 100,000 residents, according to a 2025 analysis of CDC data. Travis County (Austin) ranks No. 14 and Harris County (Houston) ranks No. 17.
Why doesn’t Texas track herpes separately in its health reports?
HSV is not a state-mandated reportable infection in Texas. The DSHS annual STD Surveillance Report covers chlamydia, gonorrhea, syphilis, and HIV — all bacterially or otherwise reportable. HSV prevalence can only be estimated through national blood-based seroprevalence surveys, not through the standard Texas disease-reporting system.
Who is most at risk for HSV in Texas?
Women face higher infection risk than men due to anatomical factors. Young adults aged 15–29 account for the majority of new STI diagnoses. Non-Hispanic Black Texans face significantly higher rates of HSV-2, reflecting systemic healthcare disparities rather than behavioral differences. All of these patterns in Texas align closely with national CDC data.
Where can HSV-positive Texans find local connection and support?
Understanding prevalence does not eliminate the emotional impact of diagnosis, but it does provide context. Millions of Texans are navigating the same questions around dating, disclosure, and relationships.If you’re looking for local resources, support communities, or ways to connect with other HSV-positive Texans, you can explore our city guides and community resources.
