Grayson County Health Department in Sherman runs its full STI panel (HIV, syphilis, gonorrhea, chlamydia, and herpes) at no cost to patients, with insurance, Medicaid, and Medicare accepted and a sliding scale applied; appointments are required, and confirmed bacterial infections are treated the same visit.
Plenty of clinics post a sliding scale and still hand back a bill. At Grayson County Health Department, the fee structure closes at zero (testing, treatment, vaccines, counseling) all of it, regardless of what insurance you carry or whether you carry any at all.
When a clinic can't provide care in Spanish directly, the gap shows up in follow-through: questions go unasked, instructions get fuzzy, and treatment stalls. Grayson County Health Department delivers STI care, counseling, and prevention education in Spanish, keeping the conversation complete from the first question to the last instruction.
Leaving herpes off the standard panel means a separate appointment, a separate cost, and a gap in the picture. Grayson County Health Department tests for herpes alongside HIV, syphilis, gonorrhea, and chlamydia. One visit covers what a narrower panel would leave open.

Callie Clinic in Sherman covers rapid HIV, hepatitis C, syphilis, gonorrhea, and chlamydia testing with same-visit treatment for bacterial infections; fees run on a sliding scale open to all, with Medicaid and insurance accepted. Appointments are required. Ryan White funding anchors its HIV care from first test through long-term treatment.
Testing positive at a clinic that handles only diagnostics leaves patients to navigate HIV care on their own, finding a provider, establishing care, managing medications across separate systems. Callie Clinic, backed by Ryan White funding, carries a patient from initial test through ongoing HIV medical treatment and medication adherence counseling within the same practice.
When PrEP or PEP requires a separate prescribing relationship, the gap between need and medication is measured in days or dropped follow-through. Callie Clinic holds that prescription capacity directly: uninsured patients can access PrEP at reduced cost, and PEP is available on-site so prevention doesn't depend on finding a second provider.
Callie Clinic provides hepatitis C treatment on-site, which means a reactive rapid hep C test doesn't send someone out the door in search of a specialist. The path from diagnosis to a treatment plan runs through the same location.

Collin County Health Care Services in McKinney requires an appointment, so scheduling is the first step, but that single visit covers gonorrhea, chlamydia, syphilis, HIV, herpes, and hepatitis testing, bacterial STI treatment, mpox and hepatitis A and B vaccines, and sliding-scale fees that extend to every service at no charge.
A separate lab bill, a prescription copay, or a vaccine charge can each quietly derail follow-through. Leaving a diagnosis handled halfway. At Collin County Health Care Services, the sliding-scale extends to zero for every service on the visit: testing, treatment, and vaccines included, with nothing held back behind a separate payment step.
Many clinics serve Spanish-speaking patients through borrowed solutions, a staff member filling in, a device held up between two people. Collin County Health Care Services delivers care in Spanish directly, so the clinical conversation about symptoms, history, and treatment happens without a layer of improvisation between the patient and the provider.
Someone without a regular provider (paying on a sliding scale, handling everything in one visit) needs a panel that doesn't leave gaps to chase elsewhere. Collin County Health Care Services tests for herpes and hepatitis A, B, and C alongside gonorrhea, chlamydia, syphilis, and HIV, closing the loop rather than generating a second appointment somewhere else.

STD stats & rates
How reported STI rates in Grayson County, the county that includes Howe, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~32% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#129 of 254 Texas counties for chlamydia, a higher rate than 49% of the state
| Infection | Grayson County | Texas | United States |
|---|---|---|---|
| Chlamydia | 295.4 434 cases ▼ 40% | 491.9 | 492.2 |
| Gonorrhea | 73.5 108 cases ▼ 58% | 176.4 | 179.5 |
| Syphilis (P&S) | 8.8 13 cases ▼ 41% | 15 | 15.8 |
| Syphilis (early) | 21.1 31 cases ▼ 20% | 26.4 | 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 Grayson County, chlamydia has fallen from 306.2 to 295.4 per 100,000 (4%), gonorrhea has fallen from 169 to 73.5 per 100,000 (57%), and P&S syphilis has risen from 0.7 to 8.8 per 100,000 (1157%).

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 Grayson County.
Local HIV snapshot
Grayson County HIV care continuum (2023)
Grayson County recorded 6.6 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Grayson County residents living with HIV, 87.5% are in care · 76.9% 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 Grayson County tests for syphilis.

Data & references
Local context
Getting tested for STIs in Howe means planning ahead. The town itself sits between larger medical centers, so same-day walk-ins aren't always realistic, and clinics that offer full testing panels may require a drive. US 75 connects Howe to nearby cities where more comprehensive services exist, but that travel adds time to an already full day. For people working multiple jobs or managing household responsibilities, a reality for many here, that logistics gap can feel substantial.
Testing in and around Howe listed on this page accounts for this reality, offering appointments that fit the schedules of working adults and households juggling competing demands. Young adults in Howe, whether they're building careers, raising families, or both, often have reason to seek confidential screening as part of routine health care. Confidentiality in a smaller community carries its own weight: results belong to you alone, shared only with providers who need them for your care. Clinics serving the area understand this and protect that trust carefully.
The affordability of life in Howe (modest housing costs, lower overall expenses) shouldn't mean skipping health care. Testing services available in and around town include low-cost and sliding-scale options, removing cost as a barrier to knowing your status.
Getting there
At 5.9/20 on the EPA walkability index, day-to-day errands in Howe 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 Texas 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 Texas, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Texas 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.
