STD stats & rates
How reported STI rates in Naguabo Municipio, the municipio that includes Rio Blanco, compare with Puerto Rico and U.S. averages, based on the most recent 2023 surveillance data.
#20 of 78 Puerto Rico counties for chlamydia, a higher rate than 74% of the state
| Infection | Naguabo Municipio | Puerto Rico | United States |
|---|---|---|---|
| Chlamydia | 183.9 42 cases ▲ 13% | 162.1 | 492.2 |
| Gonorrhea | 8.8 2 cases ▼ 76% | 37 | 179.5 |
| Syphilis (P&S) | 8.8 2 cases ▼ 35% | 13.6 | 15.8 |
| Syphilis (early) | 21.9 5 cases ▲ 12% | 19.6 | 16 |

Rates per 100,000 population, 2023. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis). Population figures: U.S. Census Bureau ACS. These figures are the latest available surveillance estimates. Bars are scaled to the highest rate shown.
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 Naguabo Municipio, chlamydia has risen from 98.3 to 183.9 per 100,000 (87%), gonorrhea has risen from 4.3 to 8.8 per 100,000 (105%), and P&S syphilis has risen from 4.3 to 8.8 per 100,000 (105%).

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 Naguabo Municipio.
Local HIV snapshot
Naguabo Municipio HIV care continuum (2022)
Naguabo Municipio recorded 0 new HIV diagnoses per 100,000 (2022), against 13.5 statewide and 13.7 nationally. Among Naguabo Municipio residents living with HIV, 51.2% are in care · 48.8% 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 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 Naguabo Municipio tests for syphilis.

Local resources & officials
Data & references
Local context
In Rio Blanco, the daily commute often begins with a long drive down Highway 19, the main road that connects the town to the rest of Naguabo Municipio. For many residents, this drive is part of their weekly routine, a necessary step to get to work or run errands. A testing visit, whether for a routine check-up or an unexpected diagnosis, can easily fit into this schedule, but the logistics of getting there can be a challenge.
The high cost of homeownership in Rio Blanco, where nearly everyone owns their own home, can also affect household budgets. With a median home value of $100,013 and a typical rent of just 7% of the median income, the financial pressures on families can be significant. For those who do rent, finding affordable options can be difficult, and this can impact the ability of residents to prioritize healthcare needs, including STI testing.
Given the rural nature of Naguabo Municipio, where Rio Blanco is located, and the limited public transportation options, driving to the nearest clinic can be a time-consuming and expensive endeavor. This reality changes the way people think about getting tested for STIs, as the convenience and accessibility of testing services can be a major barrier for many residents.
Getting there
At 3.1/20 on the EPA walkability index, day-to-day errands in Rio Blanco generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
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).
In Puerto Rico, public health clinics provide confidential STI testing and treatment; ask the clinic directly about consent requirements for minors.
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.
