STD stats & rates
How reported STI rates in Siskiyou County, the county that includes Grenada, 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.
#46 of 58 California counties for chlamydia, a higher rate than 21% of the state
| Infection | Siskiyou County | California | United States |
|---|---|---|---|
| Chlamydia | 240.1 103 cases ▼ 51% | 491.1 | 492.2 |
| Gonorrhea | 46.6 20 cases ▼ 75% | 190.2 | 179.5 |
| Syphilis (P&S) | 16.3 7 cases ≈ the state average | 16.3 | 15.8 |
| Syphilis (early) | 2.3 1 cases ▼ 88% | 19.1 | 16 |
| Syphilis (late/unknown) | 23.3 10 cases ▼ 50% | 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 Siskiyou County, chlamydia has fallen from 306.3 to 240.1 per 100,000 (22%), gonorrhea has fallen from 172.4 to 46.6 per 100,000 (73%), and P&S syphilis has fallen from 18.2 to 16.3 per 100,000 (10%).

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 Siskiyou County.
Local HIV snapshot
Siskiyou County HIV care continuum (2021)
Siskiyou County recorded 0 new HIV diagnoses per 100,000 (2021), against 14.9 statewide and 13.7 nationally. Among Siskiyou County residents living with HIV, 79.4% are in care · 69.1% 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 Siskiyou County tests for syphilis.

Local resources & officials
Data & references
Local context
Cascade Wonderland Highway cuts straight through Grenada, but daily life here runs on quieter routines. The kind shaped by households where nearly half of adults are married and the average home holds more than three people. Health decisions in that context are rarely solo calls; they ripple through families, schedules, and shared budgets. When roughly half of residents rent at modest monthly costs, that financial breathing room matters, but it also means one unexpected medical bill can feel disruptive to a carefully balanced household.
Labor-force participation here is relatively low, and unemployment runs higher than most California averages, which means a meaningful share of residents are navigating stretched weeks without the employer-sponsored coverage or predictable schedules that make clinic visits easy to slot in. For younger adults in their late teens and twenties, a sizable slice of Grenada's population, that combination of irregular income and thin transportation options along a largely rural corridor can turn "I should get tested" into something that waits far longer than it should. Siskiyou County's STI figures reflect the real costs of deferred care in a place where follow-through requires effort, and for someone living here, staying current on screening is part of keeping that household steady rather than catching up after something's already been missed.
Getting there
At 5.2/20 on the EPA walkability index, day-to-day errands in Grenada 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.
