Spanish Is the Working Language Here

Spanish is the operational language at Concilio de Salud Integral de Loiza, not an accommodation layered on top, but the default. That means clinical conversations about medication adherence, prevention options, and follow-up care happen at full depth, without anything lost in translation.

PrEP and PEP Prescribed On-Site, No Referral Needed

Concilio de Salud Integral de Loiza carries both PrEP and PEP as standing services: meaning anyone who needs ongoing HIV prevention medication, or who arrives needing post-exposure coverage, can get it prescribed and managed here without tracking down a separate provider. Sliding-scale fees apply.

Substance-Use Treatment Staffed Within the Same Clinic

The clinic staffs substance-use treatment directly alongside STI services, so a single care team can monitor medication adherence, flag interactions, and coordinate counseling without splitting the patient's record across separate programs.

Zero-Cost Care With Real Downstream Reach

All services at HealthproMed Foundation are provided at no fee, which means a patient managing ongoing HIV treatment or starting PrEP never has to weigh medication adherence counseling against what they can afford that week. The full scope of care stays available without interruption.

Spanish Is the Clinical Language Here

Spanish is the operating language of care at HealthproMed Foundation in Carolina, not a supplemental accommodation. Medication adherence counseling, HIV test counseling, and PrEP education are conducted directly in Spanish, so nuance around dosing, resistance, and risk isn't compressed into translation.

Many STI clinics stop at testing and hand prevention medication off to outside providers. HealthproMed Foundation prescribes and manages both PrEP and PEP directly, keeping the clinical relationship, and the prescription, inside the same practice where testing and HIV medical treatment already live.

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.

Local context

About Rio Grande, PR

Rio Grande carries one of the steeper STI burdens in its county, and for younger residents here, that public-health reality collides with a cost landscape that leaves little slack for discretionary appointments. With unemployment running high and barely any households clearing six figures, a testing fee that seems modest elsewhere can feel like a genuine line-item decision, which is exactly why the options listed on this page span a range of price points worth comparing before you commit to one. The city's household structure adds another layer.

Averaging nearly four people per home, many younger adults in their late teens and twenties are living with family rather than on their own, which shapes both their schedules and their sense of privacy around sexual health. Finding a site that fits those realities, one that doesn't demand a long drive on a workday morning, makes the difference for the under-35 crowd whose screening rates tend to lag furthest behind need. The clinic cards on this page show distances and hours together, so you can match both at once rather than discovering the conflict after you've already planned the trip.

What each STD test costs

Use this as a per-test benchmark before you pay out of pocket, or see the full guide to STD test costs for insurance, free, and at-home options.

Confidentiality & consent in Puerto Rico

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

Two things that actually depend on Puerto Rico 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 Puerto Rico, public health clinics provide confidential STI testing and treatment; ask the clinic directly about consent requirements for minors.

Can my partner be treated too? (EPT)

Expedited Partner Therapy (EPT) is potentially allowable in Puerto Rico: it is not expressly authorized, but not prohibited either. Ask your provider whether they will prescribe treatment for a partner without a separate visit.

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.
