STD stats & rates
How reported STI rates in Weld County, the county that includes Frederick, compare with Colorado and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~23% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#17 of 64 Colorado counties for chlamydia, a higher rate than 73% of the state
| Infection | Weld County | Colorado | United States |
|---|---|---|---|
| Chlamydia | 343.3 1,234 cases ▼ 21% | 435.1 | 492.2 |
| Gonorrhea | 66.5 239 cases ▼ 48% | 128.7 | 179.5 |
| Syphilis (P&S) | 6.1 22 cases ▼ 62% | 16 | 15.8 |
| Syphilis (early) | 3.9 14 cases ▼ 62% | 10.4 | 16 |

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread: a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.
Between 2020 and 2023 in Weld County, chlamydia has fallen from 417 to 343.3 per 100,000 (18%), gonorrhea has fallen from 126.5 to 66.5 per 100,000 (47%), and P&S syphilis has risen from 4 to 6.1 per 100,000 (52%).

Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in Weld County.
Local HIV snapshot
Weld County HIV care continuum (2023)
Weld County recorded 5.8 new HIV diagnoses per 100,000 (2023), against 9.6 statewide and 13.7 nationally. Among Weld County residents living with HIV, 77.2% are in care · 70.5% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for Weld County tests for syphilis.

Data & references
Local context
St. Vrain State Park's trails draw residents out into the landscape, but Frederick itself centers on the quieter rhythm of family life: the kind of place where people buy land, build, and stay. That stability shapes how health care works here. Testing for sexually transmitted infections happens best when it fits seamlessly into everyday routines, without disrupting the close-knit fabric of home and neighborhood.
Young adults in Frederick (whether they grew up here or moved to Firestone, Rinn Valley Ranch, or other nearby communities) benefit most from confidential screening. At this stage of life, routine testing is straightforward prevention, not crisis response. The clinics and providers listed on this page offer that privacy as standard practice, not exception. Results remain between you and your provider; no information flows to employers, family members, or others in your social circle.
Households in Frederick often span generations under one roof, and partners sometimes come from neighboring areas. Testing access in and around Frederick supports that reality: people can get screened discreetly, on their own timeline, without the weight of small-town visibility. Whether you're establishing baseline health status or following up after a potential exposure, the confidentiality built into these services is genuine.
Getting there
At 9.79/20 on the EPA walkability index, day-to-day errands in Frederick generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Two things that actually depend on Colorado law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).
In Colorado, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Colorado permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.
Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
