Spanish-Language Care Keeps the Visit Complete
When a visit has to route through translation, clinical nuance gets compressed: counseling shortens, follow-up questions go unasked, and treatment decisions lose context. At Community Health Centers in Oceano, Spanish-language care is the visit itself: history, results, and treatment conversation all happen in Spanish, without a gap between what's said and what's understood.
Herpes Testing Added to the Standard Panel
Community Health Centers in Oceano tests for herpes alongside gonorrhea, chlamydia, syphilis, and HIV. A capability that matters for anyone without a regular provider who needs answers beyond the basic four in one appointment rather than across multiple stops.

No Fee Applies Regardless of Coverage Status
Cash-pay patients and those without a regular provider face the same reality at CAPSLO: every service (testing, treatment, vaccines, PrEP) is provided at no charge. That standing policy means no calculation about which services to skip and no partial visit based on what someone can afford that day.
Spanish On-Site Keeps Care From Stalling
Without Spanish-language capacity built into the clinic itself, STI care can fracture. A test here, a follow-up call misunderstood there, treatment delayed while a third party is arranged. Community Action Partnership of San Luis Obispo delivers care directly in Spanish and through interpretation services for other languages, so nothing in the care sequence gets lost between appointments.
Truvada and PEP Prescribed and Managed Here
CAPSLO prescribes PrEP, including Truvada, and provides PEP directly, with ongoing HIV monitoring and follow-up managed at the same clinic. For uninsured patients, PrEP is available at no fee, eliminating the coverage gap that otherwise turns a preventive prescription into an unaffordable one.
Community Health Centers - Arroyo Grande, serving Arroyo Grande with federally qualified standing, ties STI screening costs directly to what patients earn. No one is turned away for inability to pay. Walk-ins are welcome for syphilis, gonorrhea, and chlamydia testing without an appointment.

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.

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 San Luis Obispo County tests for syphilis.

Confidentiality & consent in CaliforniaMinor consent and partner treatment (EPT) under state law, plus how to test privately
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).
Can a minor consent on their own?
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
Can my partner be treated too? (EPT)
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.
