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.

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 Trinity County tests for syphilis.

About Lewiston, CA

Lewiston Historic District gives this small Trinity County town its character: weathered storefronts, quiet roads, and a pace that can make routine health errands feel lower on the list than they deserve. For a community where most residents own their homes and have planted real roots here, that permanence can work in favor of consistent care, but only when the options are actually within reach. The workforce picture adds a layer worth understanding. With labor-force participation notably low, many residents may be managing caregiving, seasonal work, or retirement.

Schedules that don't follow a predictable nine-to-five. For the younger adults here, people in their late teens and twenties still building careers and relationships, fitting a screening appointment around irregular hours means having options that flex rather than demand a planned day off. The households here earning more comfortable incomes aren't the whole picture; plenty of residents are working within tighter margins. Options listed here that offer sliding-scale fees or extended hours make the difference between a test scheduled around a long shift and one that never quite gets scheduled at all, until it does, because the hours actually fit.

Confidentiality & consent in California

Minor 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.
