STD Testing in Colorado - What You Need to Know
How Common Are STDs in Colorado?
Colorado is the Centennial State — a place defined by Rocky Mountain peaks, world-class skiing, craft beer culture, and a booming Front Range corridor that stretches from Fort Collins through Denver to Colorado Springs. With over 5.8 million residents and one of the youngest, most active populations in the country, the state attracts outdoor enthusiasts, tech workers, military families, and college students in roughly equal measure.
That growth and transience fuel a sustained rise in STI rates. Gonorrhea cases in Colorado increased over 80% between 2015 and 2023, driven primarily by the Denver-Aurora metro, which accounts for the majority of statewide diagnoses. Denver County consistently ranks among the highest in the state for chlamydia and syphilis per capita, with Five Points and Capitol Hill historically carrying elevated rates. Colorado's substantial college population — including CU Boulder (40,000+ students), Colorado State in Fort Collins, and the University of Denver — concentrates a high-risk demographic along the Front Range. Mountain resort towns like Aspen, Vail, and Telluride see seasonal workforce influx that creates transmission dynamics distinct from urban counties, while rural Eastern Plains communities face the opposite challenge: sparse provider availability that leaves infections undetected. Private, walk-in lab testing gives Coloradans a fast alternative to overburdened clinics.
Colorado STD Rates: By the Numbers
STD rates across Colorado have risen sharply in recent years. According to CDC surveillance data and the Colorado Department of Public Health and Environment:
• Colorado reported over 30,000 chlamydia cases in 2023, with rates concentrated heavily along the Front Range urban corridor
• Denver County accounts for the largest share of the state's STI burden, with Aurora, Lakewood, and surrounding Adams and Arapahoe counties as secondary hotspots
• Gonorrhea cases in Colorado surged over 80% between 2015 and 2023, with Denver and El Paso County (Colorado Springs) driving the steepest increases
• Syphilis cases in Colorado more than tripled in the same period, with congenital syphilis emerging as a growing concern — particularly in Denver and Pueblo counties
• Hispanic and Latino residents face disproportionately higher rates of chlamydia relative to state averages, while Black Coloradans experience gonorrhea rates roughly 5x higher than white residents
• Young adults aged 15–24 account for the largest share of chlamydia and gonorrhea diagnoses statewide
• Many infections show no symptoms — making routine testing the only reliable way to know your status
