STD stats & rates
How reported STI rates in Modoc County, the county that includes Lake City, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~13% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#45 of 58 California counties for chlamydia, a higher rate than 22% of the state
| Infection | Modoc County | California | United States |
|---|---|---|---|
| Chlamydia | 247.1 21 cases ▼ 50% | 491.1 | 492.2 |
| Gonorrhea | — no data | 190.2 | 179.5 |
| Syphilis (P&S) | 11.8 1 cases ▼ 28% | 16.3 | 15.8 |
| Syphilis (early) | — no data | 19.1 | 16 |
| Syphilis (late/unknown) | 11.8 1 cases ▼ 75% | 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 Modoc County, chlamydia has risen from 149.4 to 247.1 per 100,000 (65%), gonorrhea has fallen from 114.9 to 47 per 100,000 (59%), and P&S syphilis has fallen from 23.1 to 11.8 per 100,000 (49%).

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 Modoc County.
Local HIV snapshot
Modoc County HIV care continuum (2023)
Modoc County recorded 0 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Modoc County residents living with HIV, 80% are in care · 80% 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 Modoc County tests for syphilis.

Data & references
Local context
Lake City draws young adults drawn to work in timber operations, wildland fire crews, and seasonal outdoor labor that shapes the region. For people in their late teens through thirties navigating those work environments, where crew dynamics matter and privacy carries real weight, STI testing in and around Lake City remains straightforward and confidential. The clinics and providers listed on this page understand that a positive result stays between you and your provider, without automatic workplace notification or community gossip. Testing availability here reflects the town's character: direct, no-frills, focused on getting accurate results without delay.
Whether you're new to the area or have roots stretching back to family land near Little Baldy or Bald Mountain, the same standard applies: you can walk in, get screened, and walk out knowing your status. Routine screening catches infections early, before symptoms emerge, which matters when your livelihood depends on showing up ready to work. The confidentiality built into these visits isn't a luxury marketed to you; it's simply how testing functions. No one gets a call at your job.
No one mails results to your home address unless you request it. That separation between your health decision and the rest of your life is what allows people in Lake City to get tested without hesitation.

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.
