The state of sexual health in Utah is a mixed bag. On one hand, the state ranks among those with the lowest rates of several major sexually transmitted diseases (STDs), including chlamydia, gonorrhea, syphilis and HIV. But on the other hand, the state has seen increases — some huge — in most STDs, which largely tracks with a trend that’s happening nationally. The U.S. has seen rates of chlamydia, gonorrhea, and primary and secondary syphilis climb for the past four straight years.

Which sexually transmitted infections and diseases are most common here in the state of Utah, how has the prevalence of certain STDs changed over the past decade, and which areas of the state are most prone to having high incidence of STDs? To answer those questions, we’ll examine data from the federal Centers for Disease Control and Prevention as well as the Utah Department of Health.

Chlamydia Rates in Utah

Utah’s population-adjusted rate of chlamydia infections is the third-lowest in the U.S., and it’s nearly 40% lower than the overall rate for the entire United States.

HIV & Other STD Rates in Utah


More than 115 people were newly diagnosed with HIV in Utah in 2017, placing the state at No. 44 nationally. In addition to being near the bottom when it comes to the prevalence of HIV, Utah also realized a huge decline in HIV between 2016 and 2017, with the population-adjusted rate falling by 18%. See How to Test for HIV

Hepatitis B & C

Utah has a lower rate of acute hepatitis B than the U.S. overall, with the national rate coming in at about four times Utah’s rate. Hep B has fluctuated widely in Utah in recent years, though it’s down about half from a high recorded in 2012. Acute hepatitis C, on the other hand, occurs in Utah at a rate more than double the national rate. Utah’s hep C rate also has climbed steadily, rising by more than 300% since 2012. See How to Test for Hepatitis


Utah’s rate of cancers related to human papillomavirus (HPV) is the lowest among all states at 8.1 per 100,000, compared to the national median of 11.7 per 100,000. It’s virtually impossible to know at any given time how many people have HPV because the virus is incredibly common (most sexually active people will get it) and very few people are ever diagnosed. But for those who have a high-risk strain of HPV and don’t get tested, the risk of several types of cancers, including cervical, penile and anal, is elevated, which is why examining the HPV-related cancer rate can help illustrate how widespread untreated HPV is in a given state.

STDs in Utah Cities & Counties

While Utah as a whole is not among the national leaders in many of the STDs we’ve examined, certain parts of the state have far higher rates of chlamydia, gonorrhea, and primary and secondary syphilis.


The Salt Lake City metro area accounted for more than 1 in 2 cases of chlamydia in Utah, and the city had the eighth-largest increase in chlamydia among all major U.S. metro areas between 2013 and 2017.

It would be easy to think sexually transmitted diseases are not a major problem in the state of Utah, given Utah’s position near the bottom of most lists of major STDs. But that ignores the major increases seen in several STDs across the state, and the surge of STDs reported in the Salt Lake City metro area. If individuals in Utah don’t take action to combat STDs, the problem will only grow. About half of sexually active people will contract an STD by the time they’re in their early to mid-20s, and most sexually active people will get at least one STD in their lifetimes. So a positive STD status is nothing to be ashamed of, and only once you know your status can you be sure you’re not passing infections along to your sexual partners.

Additional References

Note: Some states have published more recent data for chlamydia, gonorrhea, and primary and secondary syphilis. For states in which that’s the case, we have substituted the individual state data for 2018 and used that in our rankings, while other states’ rankings are based on 2017 numbers. In some cases, we assume that when the full national dataset is published by the CDC, states’ positions relative to other states will change some, though those changes are unlikely to be dramatic, since the CDC data comes from the states.
