Open Door Community Health Centers in Ferndale runs STI testing on a sliding-scale fee open to everyone, accepting Medicaid and most insurance alongside donation-based options. The standard panel covers HIV, gonorrhea, chlamydia, syphilis, herpes, and hepatitis A, B, and C. With care delivered in Spanish.
When a language barrier separates a patient from their diagnosis, the result is a postponed follow-up, a medication not understood, a treatment left incomplete. At Open Door in Ferndale, STI care (including testing, results, and treatment) is delivered in Spanish, so nothing critical gets lost between clinician and patient.
Splitting STI care and substance-use treatment across two separate providers means two intake processes, two wait times, and real gaps where follow-through breaks down. Open Door in Ferndale holds both programs, so a patient whose health needs run across both areas doesn't have to rebuild trust with an entirely separate system to get complete care.
For anyone without a regular primary care provider, or paying cash and wanting a complete picture in a single appointment, Open Door's panel extends well past gonorrhea, chlamydia, syphilis, and HIV to include herpes and hepatitis A, B, and C testing, covering exposures that a narrower clinic panel would leave unexamined.

STD stats & rates
How reported STI rates in Humboldt County, the county that includes Ferndale, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~24% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#29 of 58 California counties for chlamydia, a higher rate than 50% of the state
| Infection | Humboldt County | California | United States |
|---|---|---|---|
| Chlamydia | 332.9 446 cases ▼ 32% | 491.1 | 492.2 |
| Gonorrhea | 68.7 92 cases ▼ 64% | 190.2 | 179.5 |
| Syphilis (P&S) | 16.4 22 cases ▲ 1% | 16.3 | 15.8 |
| Syphilis (early) | 6.7 9 cases ▼ 65% | 19.1 | 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 Humboldt County, chlamydia has fallen from 395.7 to 332.9 per 100,000 (16%), gonorrhea has fallen from 188.3 to 68.7 per 100,000 (64%), and P&S syphilis has risen from 8.1 to 16.4 per 100,000 (102%).

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 Humboldt County.
Local HIV snapshot
Humboldt County HIV care continuum (2023)
Humboldt County recorded 7.7 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Humboldt County residents living with HIV, 87.4% are in care · 82.3% 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 Humboldt County tests for syphilis.

Local context
People passing through the Ferndale Tourist Information Center or stopping by the Ferndale Museum often have time to think about their health in ways a busier day doesn't allow. That quiet moment, when a conversation with staff or a walk through town prompts reflection, is exactly when questions about sexual health testing surface. Ferndale residents and visitors benefit from testing available in and around Ferndale, listed on this page, without needing to travel far for straightforward, confidential screening. Young adults in their twenties and thirties make up a significant presence here, a group for whom routine STI testing fits naturally into responsible health habits. The community's character, comfortable and stable, can sometimes make candid conversations about sexual health feel like they belong elsewhere, yet they belong precisely here.
Testing providers understand that asking for screening is ordinary care, not a crisis, and they treat it that way. Confidentiality matters in a town where many people have lived for years and know their neighbors. Testing arranged through the clinics and services listed on this page keeps results private and separate from your everyday life. Whether you're establishing baseline health before a new relationship, checking in after a known exposure, or simply staying current with preventive screening, the pathway to testing is straightforward and yours alone.

Two things that actually depend on California 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 California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
California 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.
