Famcare in Pennsville delivers STI testing and treatment through a family planning practice, pairing gonorrhea, chlamydia, syphilis, rapid and conventional HIV, and herpes screening with same-visit bacterial treatment. Walk-ins welcome, sliding scale fees, with all services available at no cost.
Famcare's no-fee model is built into how the clinic is funded and staffed: Medicaid billing, insurance processing, and sliding-scale administration are all handled on the clinic's end, so the cost reaches zero without requiring negotiation or documentation of need from the patient.
Famcare provides Spanish-language services and broader interpretation support directly, which means clinical conversations about treatment plans and medication adherence happen with full fluency. Not compressed into what a brief exchange allows.
Famcare tests for herpes in addition to gonorrhea, chlamydia, syphilis, and HIV, which means a single visit can surface an infection that the basic panel would leave undetected and unaddressed.

Henrietta Johnson Medical Center in Wilmington tests for gonorrhea, chlamydia, syphilis, and HIV, treating bacterial infections in the same visit when results warrant. Fees run on a sliding scale, with Medicaid, Medicare, and private insurance all accepted. An appointment is required. Care is delivered in Spanish.
Without Spanish-language care at the point of visit, the gap between a test result and a treatment plan often widens. A second appointment, a misunderstood follow-up, an untreated infection. At Henrietta Johnson Medical Center, Spanish is carried through the clinical encounter itself, so nothing gets lost between diagnosis and treatment.
Plenty of clinics offer family planning as a checkbox, no structural protection for younger patients who need privacy most. Henrietta Johnson Medical Center operates under Title X, which legally guarantees confidential family planning services for minors, not as a policy courtesy but as a federally binding standard.

STD stats & rates
How reported STI rates in New Castle County, the county that includes New Castle, compare with Delaware and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~20% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#2 of 3 Delaware counties for chlamydia, among the very highest in the state
| Infection | New Castle County | Delaware | United States |
|---|---|---|---|
| Chlamydia | 610.6 3,533 cases ▲ 10% | 552.7 | 492.2 |
| Gonorrhea | 184.1 1,065 cases ▲ 21% | 151.9 | 179.5 |
| Syphilis (P&S) | 19.9 115 cases ▲ 14% | 17.4 | 15.8 |
| Syphilis (early) | 9.3 54 cases ▲ 7% | 8.7 | 16 |
| Syphilis (late/unknown) | 16.8 97 cases ▲ 11% | 15.1 | 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 New Castle County, chlamydia has risen from 489 to 610.6 per 100,000 (25%), gonorrhea has risen from 143.2 to 184.1 per 100,000 (29%), and P&S syphilis has risen from 10 to 19.9 per 100,000 (99%).

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 New Castle County.
Local HIV snapshot
New Castle County HIV care continuum (2023)
New Castle County recorded 13 new HIV diagnoses per 100,000 (2023), against 11.4 statewide and 13.7 nationally. Among New Castle County residents living with HIV, 83% are in care · 72.6% 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 New Castle County tests for syphilis.

Local resources & officials
Data & references
Local context
Delaware Street cuts through New Castle's historic core with a pace that belies how tightly budgets run here, typical rents hovering just above twelve hundred a month mean that for the roughly one-in-three households who lease rather than own, discretionary spending on healthcare can feel like a luxury reshuffled every billing cycle. That financial texture matters when you consider who's most likely to need STI screening: people in their late teens and twenties, still building careers and relationships, often juggling the kind of variable hours that make a weekday clinic appointment feel genuinely hard to arrange. New Castle's workforce participation is solid, and with nearly a third of households clearing six figures, there's a cross-section of financial stability here, but the renters around Colonial Village Apartments or along the Penn Acres side of town don't always share in that cushion.
Cost hesitation and scheduling pressure together can quietly steer someone away from testing they'd otherwise pursue. Not just one clinic to work around. Whether someone is walking distance from the George Read II House or commuting out along DE 141, the odds of finding a time and place that actually fits are better here than in most surrounding areas.
Getting there
New Castle scores 11.51/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

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 Delaware 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 Delaware, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
Delaware 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.
