Prevention Prescriptions Written at This Clinic

Prevention medication often stops at whatever the testing clinic can offer, which, at many practices, means a conversation and nothing further. MainStreet Family Care writes PrEP and PEP prescriptions directly, keeping both ongoing prevention and post-exposure response inside the same practice where the testing happened.

Herpes and Hepatitis Tested Alongside the Standard Four

The expanded panel at MainStreet Family Care adds herpes simplex and both hepatitis B and hepatitis C testing to the core screen: hepatitis B antibody results also inform whether the on-site adult hepatitis B vaccine series is warranted, linking diagnosis and prevention within the same visit.

STDs & HIV in Nassau County: the local picture

How reported STI rates in Nassau County, the county that includes Callahan, compare with Florida and U.S. averages, based on the most recent 2023 surveillance data.

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 Nassau County tests for syphilis.

Confidentiality & consent in Florida

Minor consent and partner treatment (EPT) under state law, plus how to test privately

Two things that actually depend on Florida 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 Florida, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.

Can my partner be treated too? (EPT)

Florida 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.
