Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Planned Parenthood Northern California in Eureka covers herpes, chlamydia, gonorrhea, syphilis, and rapid HIV testing on a sliding-scale fee, with same-visit treatment for bacterial infections: appointments required, and Spanish-language care available on-site.
When a language barrier interrupts STI care at Planned Parenthood Northern the result isn't a delayed conversation, it's a delayed diagnosis or a missed prescription. Spanish speakers and patients needing interpretation receive that support here, in the same appointment where testing, counseling, and treatment happen.
Planned Parenthood Northern California holds Title X designation, which means its family planning services, including STI testing and contraception, are legally confidential for minors. A young person without a regular provider, paying out of pocket, or navigating care without a parent's knowledge has a defined legal framework protecting that visit here.
PrEP, including medications like Truvada, requires ongoing HIV testing and prescription monitoring, all of which Planned Parenthood Northern California carries out in-clinic rather than routing through a separate provider. PEP is also available, meaning both prevention pathways stay within one clinical relationship.

Open Door RX, serving Eureka under federally qualified health center standing, extends sliding-scale STI screening (syphilis, gonorrhea, and chlamydia) to patients at fees calibrated to household income, so cost is never a fixed barrier to getting tested.
Tests offered
Fees & payment
Open Door Community Health Centers in Eureka tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis on a sliding-scale fee, meaning everyone qualifies, with same-visit treatment for bacterial infections; appointments are required, and care is delivered in Spanish.
Plenty of clinics can arrange someone on a phone to translate a diagnosis. Open Door Eureka delivers the care itself in Spanish (history, counseling, treatment) without the friction of a third channel sitting between clinician and patient.
Open Door's standing capacity to treat substance-use issues alongside STIs serves people whose health needs don't separate neatly by department. Managing both in one place means a single appointment can address co-occurring concerns without coordinating across separate providers.
For anyone without a regular primary-care provider, or paying out of pocket and unwilling to make two separate trips, Open Door's expanded panel covers herpes and hepatitis A, B, and C alongside the standard four, making one appointment genuinely complete.

STD stats & rates
How reported STI rates in Humboldt County, the county that includes Humboldt Hill, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~21% 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%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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.

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 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.
