Keeping prevention and monitoring at one provider means dosing schedules and lab intervals don't get fragmented across separate offices.
Leaving herpes or hepatitis B and C off a panel means a separate appointment, a separate lab, and a gap where an active infection goes unaddressed. MainStreet Family Care in Starke includes herpes, hepatitis B, and hepatitis C in its standard testing alongside HIV, syphilis, gonorrhea, and chlamydia, so a complete picture comes from a single visit.

STD stats & rates
How reported STI rates in Clay County, the county that includes Keystone Heights, compare with Florida and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~27% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#43 of 67 Florida counties for chlamydia, a higher rate than 36% of the state
| Infection | Clay County | Florida | United States |
|---|---|---|---|
| Chlamydia | 340.7 792 cases ▼ 32% | 498.9 | 492.2 |
| Gonorrhea | 114.4 266 cases ▼ 45% | 206.7 | 179.5 |
| Syphilis (P&S) | 11.2 26 cases ▼ 42% | 19.3 | 15.8 |
| Syphilis (early) | 5.6 13 cases ▼ 78% | 25.1 | 16 |
| Syphilis (late/unknown) | 15.9 37 cases ▼ 58% | 37.7 | 29.5 |

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 Clay County, chlamydia has fallen from 352.8 to 340.7 per 100,000 (3%), gonorrhea has fallen from 144.3 to 114.4 per 100,000 (21%), and P&S syphilis has risen from 5 to 11.2 per 100,000 (124%).

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 Clay County.
Local HIV snapshot
Clay County HIV care continuum (2023)
Clay County recorded 14.8 new HIV diagnoses per 100,000 (2023), against 22.7 statewide and 13.7 nationally. Among Clay County residents living with HIV, 80.2% are in care · 69.8% 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 Clay County tests for syphilis.

Data & references
Local context
SR 100 cuts straight through Keystone Heights as Walker Drive, and for most residents the daily rhythms here are shaped by households rather than commutes: nearly half of adults are married, and with an average household size well above three people, health decisions often get weighed collectively, factored against rent, schedules, and everyone else's needs before one's own. That family-centered dynamic matters for sexual health in particular. A town where most residents own their homes tends toward stability, but the roughly three-in-ten households renting at around a thousand dollars a month know how quickly a month's expenses crowd out anything that isn't urgent. With well under two-thirds of residents in the labor force, and those who are often working hours that don't align neatly with clinic appointments, the options listed on this page carry real weight.
Younger adults in their late teens and twenties, a meaningful share of Keystone Heights' population, are precisely the group for whom a complicated or costly visit most often becomes one that simply never gets scheduled. Keystone Beach and McDavid Park anchor community life here, but getting tested means leaving town on SR 100, a reality worth planning around rather than discovering en route. Clay County's STI figures aren't abstract numbers for someone living here: they represent actual neighbors, and staying current on screening is how you stay ahead of what those counts reflect.
Getting there
At 6.53/20 on the EPA walkability index, day-to-day errands in Keystone Heights 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 Florida 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 Florida, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Florida 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.
