NOVA Patient Care in Alexandria tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis B and C: all on a sliding scale, with same-visit treatment for bacterial infections and an appointment required to be seen.
Every service at NOVA Patient Care is provided at no fee, which means the full scope of testing, treatment, and prevention (PrEP, hepatitis care, HIV management) stays financially within reach on the same visit without a cost calculation standing between a patient and the next step.
NOVA Patient Care delivers care directly in Spanish, so medication adherence counseling, HIV prevention education, and treatment decisions happen in the language a person uses to weigh medical choices. Not summarized after the fact.
Without an on-site PrEP provider, the period between a prevention conversation and an actual prescription can stretch into weeks of unprotected exposure. NOVA Patient Care prescribes and manages PrEP directly, closing that gap at the same appointment where HIV testing and counseling happen.

Community of Hope in Washington tests for HIV, gonorrhea, chlamydia, syphilis, herpes, hepatitis A, B, and C, and TB, treating bacterial STIs the same visit under a sliding-scale fee that covers everyone. Appointments required, with care delivered in Spanish.
Community of Hope delivers care in Spanish across the full scope of its STI and HIV services, not through an external aid but as a native operational capacity. That means PrEP counseling, hepatitis treatment discussions, and medication adherence education all proceed in Spanish without a handoff or delay.
When PrEP or PEP isn't available at a testing site, the gap between a conversation and a prescription can stretch into days across multiple providers. Community of Hope in Washington prescribes both, so prevention isn't deferred to a separate clinic visit or an outside referral chain.
A positive hepatitis C antibody result at Community of Hope doesn't end the clinical relationship, on-site treatment means the prescribing and monitoring continue here. That continuity keeps medication adherence education, which the clinic provides directly, connected to the treatment itself rather than split across providers.

Inova-GoHealth Urgent Care in Alexandria tests for gonorrhea, chlamydia, syphilis, herpes, HIV, hepatitis A, B, and C, and TB, treating bacterial infections the same visit, with fees billed to insurance or Medicaid, or paid directly on a sliding scale. Walk-ins welcome; interpretation services available.
Navigating STI care in a second language requires more than a working vocabulary: it requires accurate symptom history, understood treatment instructions, and informed consent. Inova-GoHealth carries interpretation services directly into the clinical encounter in Alexandria, so nothing critical gets compressed or lost across the desk.
Leaving a clinic with gonorrhea and chlamydia results but no herpes or hepatitis answer means scheduling a second appointment somewhere else, another wait, another copay, another week without clarity. Inova-GoHealth's panel in Alexandria covers herpes, hepatitis A, B, and C alongside the core bacterial infections, so the picture is complete after one visit.

Neighborhood Health in Alexandria is a community health center where STI care sits alongside ongoing medical services: meaning gonorrhea, chlamydia, syphilis, herpes, hepatitis A, B, and C, TB, and rapid or conventional HIV testing are all available, with same-visit treatment for bacterial infections, on a sliding scale, with all services provided at no fee.
When cost gets in the way, bacterial infections go untreated, follow-up labs get skipped, and hepatitis B or C management stalls mid-course. At Neighborhood Health, every service (testing, treatment, vaccines, HIV care) carries no charge, so nothing on the care plan gets quietly dropped because of what it would cost.
Neighborhood Health in Alexandria provides care directly in Spanish and through interpretation services for other languages, not as a workaround but as part of how clinical conversations happen. For someone managing PrEP adherence, discussing hepatitis treatment, or working through a positive result, having that exchange in their own language is part of the medical care itself.
Neighborhood Health prescribes both PrEP and PEP directly, with the clinical staffing to manage what each requires, for PrEP, that means baseline HIV and kidney function testing, ongoing labs at regular intervals, and prescription renewals; for PEP, it means a full 28-day course initiated and tracked here in Alexandria.

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 Prince George's County, chlamydia has risen from 721 to 728.7 per 100,000 (1%), gonorrhea has risen from 248.8 to 284.3 per 100,000 (14%), and P&S syphilis has fallen from 16.9 to 15.3 per 100,000 (9%).

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 Prince George's County.

Prince George's County HIV care continuum (2023)
Prince George's County recorded 24.7 new HIV diagnoses per 100,000 (2023), against 13.9 statewide and 13.7 nationally. Among Prince George's County residents living with HIV, 88.4% know their status · 73.4% are in care · 66.5% 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 Prince George's County tests for syphilis.

Two things that actually depend on Maryland 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 Maryland, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Maryland 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.
