A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Chota Community Health Services in Vonore pairs same-visit treatment for bacterial STIs (gonorrhea, chlamydia, syphilis) with testing on a sliding-scale fee open to everyone, no appointment required, with care delivered in American Sign Language, Chinese, French, Haitian Creole, and more.
Chota provides clinical services directly in American Sign Language, Chinese, French, Haitian Creole, Portuguese, Spanish, Tagalog, and Vietnamese: meaning test results, treatment decisions, and counseling happen in the same language the conversation started in, without delay or relay.
Without access to both PrEP and PEP at Chota Community Health Services, a gap in prevention coverage means hunting down a prescriber and losing days, sometimes weeks, to scheduling. Vonore residents can initiate and manage both here, with dedicated support for uninsured patients covering PrEP costs.
Chota tests for herpes, hepatitis A, hepatitis B, and hepatitis C in addition to gonorrhea, chlamydia, syphilis, and HIV, which means infections that would otherwise go undetected without a separate referral are caught and addressed in the same visit.

Tennessee Department of Health in Loudon covers HIV, syphilis, gonorrhea, chlamydia, hepatitis C, and TB testing on a sliding-scale fee, with HIV and STI tests free; Medicaid is accepted, appointments are required, and all services are provided at no fee.
Tennessee Department of Health in Loudon extends its no-fee structure to every service on the menu (testing, treatment, vaccines, DoxyPEP) whether someone pays cash, carries Medicaid, or has no coverage at all. That standing policy means no bill arrives later and no service gets quietly withheld.
Tennessee Department of Health in Loudon prescribes DoxyPEP as a routine prevention service, which means eligible patients leave with the medication rather than waiting on an outside pharmacy to fill an unfamiliar order.
Without on-site hepatitis C treatment, a reactive test result triggers a separate specialist referral. Another appointment, another wait, another gap where the infection continues unchecked. Tennessee Department of Health in Loudon closes that gap by carrying treatment through to completion on-site.

River Valley Health in Lenoir City anchors STI care within a full-service community health framework, covering gonorrhea, chlamydia, syphilis, herpes, HIV, hepatitis A, B, and C, and TB on a sliding-scale fee open to everyone, with walk-in availability, same-visit treatment for bacterial infections, and interpretation services for non-English speakers.
River Valley Health prescribes and monitors antiviral therapy for hepatitis C directly through its clinical staff: meaning the provider who confirms the diagnosis is also the one managing the treatment course, tracking viral load response, and adjusting care without handing off to an outside specialist.
Many clinics screen for HIV but stop short of prescribing the medications that prevent it, River Valley Health writes PrEP prescriptions and provides PEP, keeping the full prevention continuum with the same provider rather than splitting care across separate practices.
Interpretation services at River Valley Health connect non-English speakers directly to the clinician during the visit itself, so that questions about a diagnosis, a treatment plan, or a prevention medication get a real answer in the room rather than a deferred one.

STD stats & rates
How reported STI rates in Loudon County, the county that includes Greenback, compare with Tennessee and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~35% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#71 of 95 Tennessee counties for chlamydia, a higher rate than 25% of the state
| Infection | Loudon County | Tennessee | United States |
|---|---|---|---|
| Chlamydia | 193.1 117 cases ▼ 63% | 517.4 | 492.2 |
| Gonorrhea | 42.9 26 cases ▼ 77% | 186.4 | 179.5 |
| Syphilis (P&S) | 11.6 7 cases ▼ 22% | 14.8 | 15.8 |
| Syphilis (early) | 1.7 1 cases ▼ 85% | 11.5 | 16 |
| Syphilis (late/unknown) | 3.3 2 cases ▼ 87% | 26.4 | 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 Loudon County, chlamydia has fallen from 267.8 to 193.1 per 100,000 (28%), gonorrhea has fallen from 56.5 to 42.9 per 100,000 (24%), and P&S syphilis has risen from 3.6 to 11.6 per 100,000 (222%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Loudon County.
Local HIV snapshot
Loudon County HIV care continuum (2021)
Loudon County recorded 10.2 new HIV diagnoses per 100,000 (2021), against 14.8 statewide and 13.7 nationally. Among Loudon County residents living with HIV, 81.3% are in care · 75% 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 Loudon County tests for syphilis.

Local resources & officials
Data & references
Local context
Fort Loudoun's ridgeline sits quiet above a town where nearly four in five households own their homes, roots run deep in Greenback. But that settled character coexists with a labor market where a meaningful share of working-age adults are outside the workforce entirely, and those who are employed often keep hours that leave little room for a weekday clinic appointment. Those practical pressures land unevenly on younger adults still in the relationship-forming years of their lives, the stretch from late teens through the mid-thirties when STI transmission is most concentrated. For a household juggling a large family under one roof, that trip is a real scheduling ask, not an afterthought.
Cost is its own layer. The roughly one-in-four Greenback households earning above six figures has flexibility that others here don't. For the renter paying around a thousand dollars a month, a genuine share of income in a modest-wage area, the fee column in the clinic cards on this page matters: the difference between a sliding-scale option and a flat-rate visit can be the detail that determines which appointment actually gets booked.
Getting there
At 4.69/20 on the EPA walkability index, day-to-day errands in Greenback generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
Two things that actually depend on Tennessee 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 Tennessee, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Tennessee 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.
