Planned Parenthood Mar Monte in Manteca tests for gonorrhea, chlamydia, syphilis, herpes, and HIV on a sliding-scale fee with no appointment required; bacterial STIs are treated same visit, and Spanish plus interpretation services extend that access across languages.
Spanish is spoken directly at this Manteca location, and interpretation services extend that reach to additional languages. Meaning every clinical conversation, from PrEP counseling to STI treatment, carries the same weight regardless of which language a patient reasons in.
Title X designation makes this clinic's family planning and STI services legally confidential for minors, a specific statutory protection, not a policy preference. That distinction gives younger patients access to the full panel and treatment without parental disclosure requirements.
For anyone without a regular prescribing provider, Planned Parenthood Mar Monte maintains standing capacity to initiate and manage both PrEP and PEP. Meaning ongoing HIV prevention medication doesn't require tracking down a separate infectious disease practice or coordinating across multiple offices.

STD stats & rates
How reported STI rates in San Joaquin County, the county that includes Ripon, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~23% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#10 of 58 California counties for chlamydia, a higher rate than 83% of the state
| Infection | San Joaquin County | California | United States |
|---|---|---|---|
| Chlamydia | 529.6 4,242 cases ▲ 8% | 491.1 | 492.2 |
| Gonorrhea | 156.8 1,256 cases ▼ 18% | 190.2 | 179.5 |
| Syphilis (P&S) | 17.5 140 cases ▲ 7% | 16.3 | 15.8 |
| Syphilis (early) | 24.3 195 cases ▲ 27% | 19.1 | 16 |
| Syphilis (late/unknown) | 58.1 465 cases ▲ 24% | 46.7 | 29.5 |

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 San Joaquin County, chlamydia has risen from 465.3 to 529.6 per 100,000 (14%), gonorrhea has fallen from 185.7 to 156.8 per 100,000 (16%), and P&S syphilis has fallen from 23.6 to 17.5 per 100,000 (26%).

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 San Joaquin County.
Local HIV snapshot
San Joaquin County HIV care continuum (2023)
San Joaquin County recorded 15.4 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among San Joaquin County residents living with HIV, 76% are in care · 68.5% 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 San Joaquin County tests for syphilis.

Data & references
Local context
CA 99 runs right past Ripon's edge, and the nearest clinic listed here is a straight shot up the Golden State Highway, rarely more than fifteen or twenty minutes from town. That geographic reality matters because Ripon is a working community: most adults here own their homes, households tend to be larger than the state average, and more than half of married adults are raising families in houses they're paying off. A mortgage and a full household schedule can crowd out a midday appointment just as easily as a tight budget can.
The town's life-stage mix reinforces why accessible options matter. Young adults in their late teens and twenties represent a meaningful slice of Ripon's population, and people at that stage, whether newly settled near Historic Ripon or renting while they save, are in the years when STI rates run highest and routine screening is most likely to catch something before symptoms do. Nearly four in ten households here clear six figures annually, yet even comfortable incomes don't automatically translate into free afternoons, and the options listed on this page include sliding-scale and low-cost visits that remove cost as a reason to wait.
Ripon's household profile, larger families, high ownership rates, a strong share of partnered adults, means that one person's undetected infection rarely stays one person's concern for long. Testing fits the same practical logic as any other routine health task families here stay on top of.
Getting there
At 9.28/20 on the EPA walkability index, day-to-day errands in Ripon generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
