HealthLinc in Knox is a community health center where STI care (gonorrhea, chlamydia, syphilis, and HIV testing with same-visit bacterial treatment) sits alongside primary and family planning services, all on a sliding-scale fee with appointments required. Spanish-language care is available on-site.
HealthLinc carries Spanish as a working clinical language, meaning conversations about symptoms, test results, and treatment instructions happen directly in Spanish. Not summarized afterward or filtered through a secondary channel. For patients whose primary language is Spanish, that directness shapes what gets communicated and what actually gets understood.
HealthLinc offers substance-use treatment at the same site as STI care, so a provider managing both conditions can coordinate timing and flag interactions between treatments. Rather than leaving that coordination to the patient across separate systems.

Fees & payment
Marshall County Health Department in Plymouth requires an appointment and covers gonorrhea, chlamydia, HIV, hepatitis C, and TB testing in a single visit, with bacterial STIs treated same day on a sliding-scale fee structure, and every service carries no charge at the point of care.
Beyond the four bacterial and viral STI tests, Marshall County adds hepatitis C and TB to the standing panel: meaning both are ordered alongside gonorrhea, chlamydia, and HIV without a separate visit or referral. For anyone managing overlapping exposure risks, that coverage arrives in one appointment.
Marshall County Health Department accepts Medicaid, Medicare, and private insurance, and for anyone outside those programs the sliding-scale absorbs the remainder. The operational result being that no service generates an out-of-pocket balance. HIV and hepatitis C testing are specifically free by policy, independent of any coverage status.

STD stats & rates
How reported STI rates in Starke County, the county that includes Knox, compare with Indiana and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~25% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#71 of 92 Indiana counties for chlamydia, a higher rate than 23% of the state
| Infection | Starke County | Indiana | United States |
|---|---|---|---|
| Chlamydia | 172.4 40 cases ▼ 65% | 491 | 492.2 |
| Gonorrhea | 30.2 7 cases ▼ 79% | 144 | 179.5 |
| Syphilis (P&S) | — no data | 8.7 | 15.8 |

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 Starke County, chlamydia has risen from 124.1 to 172.4 per 100,000 (39%), gonorrhea has risen from 25.7 to 30.2 per 100,000 (18%), and P&S syphilis has risen from 4.3 to 8.6 per 100,000 (100%).

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 Starke County.
Local HIV snapshot
Starke County HIV care continuum (2022)
Starke County recorded 0 new HIV diagnoses per 100,000 (2022), against 11.7 statewide and 13.7 nationally. Among Starke County residents living with HIV, 80% are in care · 70% 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 Starke County tests for syphilis.

Data & references
Local context
Heritage Park anchors the quieter side of Knox, and the households gathered around it reflect a town where families run large and decisions, including health ones, tend to get made collectively. With average household sizes well above the national norm and more than a third of adults married, a health choice here rarely feels purely individual; it gets weighed against schedules, budgets, and the needs of everyone under one roof. That household math intersects with some real economic constraints. Nearly half of Knox residents rent, and at typical rents that still leave little room after groceries and utilities in a county where high earners are scarce.
Labor-force participation is relatively modest, and unemployment runs noticeably higher than state averages, which means unpredictable schedules are common. A morning open for a clinic visit can disappear fast. For people in their late teens and twenties, the years when new relationships and new partners are most frequent, that combination of distance and shifting work hours is what actually determines whether screening happens. Starke County's STI figures give residents a clear reason to stay current rather than wait for symptoms, and for anyone building a life here, routine testing is simply part of knowing where things stand.
Getting there
At 5.31/20 on the EPA walkability index, day-to-day errands in Knox 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 Indiana 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 Indiana, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Indiana 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.
