Inland Empire Womens Center in Fontana tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis A, B, and C on a sliding-scale fee with insurance accepted; appointments are required, and bacterial infections can be treated the same visit. Care is delivered in Spanish.
For anyone whose primary language is Spanish (especially those without a regular provider who need to describe symptoms, weigh treatment options, or understand a diagnosis) Inland Empire Womens Center conducts care directly in Spanish. Nothing gets filtered through a secondary channel; the clinical conversation happens in the language you reason in from start to finish.
Inland Empire Womens Center prescribes both PrEP, the daily oral medication that keeps HIV from establishing infection, and PEP, and maintains a dedicated coverage pathway for uninsured patients seeking PrEP. That means the prescription, and the monitoring it requires, aren't contingent on having a plan card.
Anyone without a regular primary care provider, and therefore no easy avenue for add-on testing, benefits from a panel that runs well past the core four. Inland Empire Womens Center tests for herpes, hepatitis A, B, and C, and TB in the same appointment, so a single visit can answer questions that would otherwise require separate referrals.

STD stats & rates
How reported STI rates in San Bernardino County, the county that includes Fontana, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~30% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#8 of 58 California counties for chlamydia, a higher rate than 86% of the state
| Infection | San Bernardino County | California | United States |
|---|---|---|---|
| Chlamydia | 562.1 12,342 cases ▲ 14% | 491.1 | 492.2 |
| Gonorrhea | 164.6 3,615 cases ▼ 13% | 190.2 | 179.5 |
| Syphilis (P&S) | 14.3 315 cases ▼ 12% | 16.3 | 15.8 |
| Syphilis (early) | 18.9 415 cases ▼ 1% | 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 San Bernardino County, chlamydia has risen from 484.5 to 562.1 per 100,000 (16%), gonorrhea has fallen from 197 to 164.6 per 100,000 (16%), and P&S syphilis has fallen from 17.5 to 14.3 per 100,000 (18%).

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 Bernardino County.
Local HIV snapshot
Federal priority area: San Bernardino County is one of 48 U.S. counties prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
San Bernardino County HIV care continuum (2023)
San Bernardino County recorded 16.3 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among San Bernardino County residents living with HIV, 78% know their status · 69.6% are in care · 62.3% 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 San Bernardino County tests for syphilis.

Data & references
Local context
Along Foothill Boulevard, the heart of Fontana pulses with a mix of commerce and community. Here, families and young adults live in a landscape of modest homes and apartments, many with a mortgage to call their own. The area's housing tenure is largely owner-dominated, with over half of residents holding a deed.
Residents of Fontana balance work and family life, with many households having multiple earners and a good number of adults holding jobs that keep them busy. With a strong presence of households with higher incomes and larger families, everyday life can get hectic. For young adults still forming relationships, getting screened for STIs might seem like a low priority. Yet, with convenient options, they can take care of their health without disrupting their busy lives.
In the neighborhoods around Summerwood Way Park and Central City Park, life unfolds in a rhythm of work, family, and community. As people in their late teens and twenties navigate their lives, having easy access to low-friction screening can make all the difference, allowing them to take care of their health as they go about their daily lives, juggling work, family, and personal responsibilities in places like the Lifestyle neighborhood, near the Base line and Cherry avenues.

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.
