Infectious Disease Associates in Columbia brings specialist-level depth to STI care: the full bacterial panel, rapid and conventional HIV testing, hepatitis B and C screening, sliding-scale fees, and same-visit treatment for bacterial infections. All by appointment.

PrEP and PEP Prescribed Where You Test
Prevention medication rarely lives in the same building as STI testing, most practices hand off the prescription conversation elsewhere. At Infectious Disease Associates, both PrEP and PEP are prescribed on-site, meaning the clinical relationship that informs your prevention plan is the same one reading your lab work.
Hepatitis C Treatment Stays In-House
Infectious Disease Associates carries direct-acting antiviral treatment for hepatitis C on-site, which means a confirmed diagnosis doesn't transfer to a separate specialist. The prescribing authority and monitoring are already in the same practice that ran the test.
Hepatitis B and C on the Panel by Default
The panel at Infectious Disease Associates includes hepatitis B and C alongside the standard bacterial and HIV tests, so a single appointment produces a more complete infection picture. One that can catch chronic conditions that a narrower screen would miss entirely.

Chase Brexton Health Care in Columbia extends its full STI panel (HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis A, B, and C, and TB) on a sliding-scale fee with no cost at the floor, accepting Medicaid, Medicare, and most insurance; appointments are required, and bacterial infections are treated the same visit.
Read full overviewShow less
Every Service Here Carries Zero Cost
Chase Brexton provides all of its services at no charge, which means the sliding scale bottoms out at nothing: PrEP, DoxyPEP, hepatitis C treatment, and HIV care all fall under the same no-fee ceiling. The practical effect: cost doesn't filter what care a patient can actually receive.
Spanish-Language Care Across Every Service Line
Spanish is a working clinical language at Chase Brexton in Columbia, running through the same service lines as the rest of care: PrEP counseling, DoxyPEP prescribing, hepatitis C treatment, and HIV management. That continuity means medication decisions and follow-up protocols are handled directly in Spanish, not relayed through a secondary step.
Ryan White Funding Covers HIV Care End to End
Chase Brexton carries Ryan White Program funding, which means HIV care doesn't stop at a positive test. Ongoing antiretroviral management is available for people without a regular HIV provider or without insurance coverage that would otherwise make long-term treatment viable. The funding is built into the clinic's structure, not a contingency.

Zero Fee Applies to Every Service Listed
The no-fee structure at Howard County Health Department isn't limited to HIV testing: it covers the full panel, TB testing and treatment, family planning, and vaccines including HPV and hepatitis A and B. Sliding scale is the policy; zero is consistently where it lands.
Eight Languages Staffed, Not Contracted Out
Howard County Health Department maintains direct-service capacity in American Sign Language, Chinese, French, Haitian Creole, Portuguese, Spanish, Tagalog, and Vietnamese. Eight languages handled by staff or on-site interpreters, not routed through an outside service. That means clinical conversations, not transcribed exchanges.
When prevention requires medication, whether ongoing PrEP or post-exposure PEP, a gap between the conversation and the prescription is where coverage breaks down. Howard County Health Department prescribes and manages both here, so neither requires a separate provider visit to initiate or continue.

Chase Brexton Health Services, Inc. at Way Station, in Columbia, anchors its STI care in a sliding-scale fee structure tied to income. Federal qualification backs that commitment. Walk-in STI screening covers syphilis, gonorrhea, and chlamydia, with costs adjusted so that inability to pay is never a barrier.
Caring Hands Medical Clinic in Laurel covers gonorrhea, chlamydia, syphilis, herpes, hepatitis B, hepatitis C, and HIV by appointment, treating bacterial infections the same visit and billing Medicaid or insurance, with a direct fee for those paying out of pocket.

Emtricitabine-Tenofovir on an Ongoing Prescription Here
Caring Hands carries both PrEP, daily oral emtricitabine/tenofovir, and PEP within its standard clinical offering. Maintaining a PrEP prescription requires regular HIV and kidney-function monitoring, and that follow-up care runs through the same clinic rather than being split across separate providers.
Herpes and Hepatitis Testing for People Without a Regular Provider
Anyone managing their sexual health without a primary-care relationship often finds herpes and hepatitis B and C testing unavailable at narrower clinics. Caring Hands extends its panel to all three, meaning a single appointment can establish a complete baseline. Including infections that standard four-test panels routinely leave unconfirmed.

Petro Health in Catonsville tests for HIV, syphilis, hepatitis C, gonorrhea, and more on a sliding-scale fee, with insurance and Medicaid accepted; appointments are required, and same-visit treatment is available for bacterial infections. French-language care is available throughout.
Read full overviewShow less
French-Language Care, Start to Finish
When a visit depends on understanding a diagnosis, or explaining symptoms precisely, miscommunication between a provider and a French-speaking patient can mean delayed treatment, missed follow-up, or a prescription misunderstood. At Petro Health, clinical care is conducted in French, so nothing critical gets lost between the appointment and the outcome.
PrEP, PEP, and DoxyPEP Prescribed and Monitored Here
Petro Health prescribes and manages all three current HIV and bacterial STI prevention regimens: daily oral PrEP with the lab monitoring that keeps it active, PEP for post-exposure HIV prevention, and DoxyPEP: doxycycline taken after a sexual exposure to reduce the risk of syphilis, gonorrhea, and chlamydia. Each requires ongoing clinical oversight, which the clinic provides directly.
Hepatitis C Diagnosed and Treated at Petro Health
Hepatitis C left untreated causes progressive liver damage, and every week between a positive result and a treatment prescription is a week the virus continues that work. At Petro Health in Catonsville, the gap closes on-site: antiviral treatment is managed here, so a confirmed hepatitis C diagnosis moves directly into a treatment plan without a separate specialist referral.

Herpes and Hepatitis Alongside the Standard Four
Mobile Medical Care runs a panel that extends to herpes simplex and hepatitis A, B, and C: infections beyond gonorrhea, chlamydia, syphilis, and HIV. Knowing your hepatitis status in the same appointment changes what you walk away prepared to monitor or treat.
PrEP Prescribed On-Site, Including for the Uninsured
Mobile Medical Care holds the standing capacity to prescribe and support PrEP directly, no separate referral to a primary care physician required, and covers the uninsured through dedicated PrEP access funding. PEP is also available for prevention, handled within the same clinical relationship.
Interpretation Services Connect Directly to Clinical Care
Mobile Medical Care makes interpretation services available for non-English languages, and the direct consequence is that medication adherence counseling, the part of care most dependent on precision and nuance, reaches patients fully in the language they use to make decisions about their health.

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.

Among Howard County residents living with HIV, 80.8% are in care · 74.4% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.

Pregnant or planning to be?Congenital syphilis is the fastest-rising STI: what to test, and when
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 Howard County tests for syphilis.

Columbia's labor market runs deep, with nearly three in four residents in the workforce, the weekday calculus of getting tested here is real. That scheduling pressure lands unevenly. Younger adults (people in their late teens and twenties navigating new relationships, new jobs, new living situations) are precisely who benefits most from clinics that stay open past the standard nine-to-five. Columbia skews toward established households: more than half of adults are married, the average home holds over three people, and nearly two-thirds own their homes. That stability doesn't mean everyone has easy access.
Renters, who face some of the steeper monthly housing costs in the region, carry a cost-pressure that can make anything with an out-of-pocket fee feel like a negotiation. Knowing which of the listed options offer sliding-scale or no-cost visits matters. The neighborhoods spreading out from Symphony Woods toward Stevens Forest and Dasher Green aren't dense with transit, so the best screening option isn't always the nearest clinic. It's the one whose hours actually fit around a commute on Little Patuxent Parkway.

Confidentiality & consent in MarylandMinor consent and partner treatment (EPT) under state law, plus how to test privately
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).
Can a minor consent on their own?
In Maryland, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Can my partner be treated too? (EPT)
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.
