STD stats & rates
How reported STI rates in Ascension Parish, the parish that includes Donaldsonville, compare with Louisiana and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~25% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#46 of 64 Louisiana counties for chlamydia, a higher rate than 28% of the state
| Infection | Ascension Parish | Louisiana | United States |
|---|---|---|---|
| Chlamydia | 597.1 786 cases ▼ 25% | 792.4 | 492.2 |
| Gonorrhea | 159.5 210 cases ▼ 45% | 288.4 | 179.5 |
| Syphilis (P&S) | 12.2 16 cases ▼ 53% | 26.1 | 15.8 |
| Syphilis (early) | 18.2 24 cases ▼ 7% | 19.6 | 16 |
| Syphilis (late/unknown) | 40.3 53 cases ▼ 23% | 52.6 | 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 Ascension Parish, chlamydia has risen from 579.4 to 597.1 per 100,000 (3%), gonorrhea has fallen from 212.6 to 159.5 per 100,000 (25%), and P&S syphilis has risen from 4.7 to 12.2 per 100,000 (160%).

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 Ascension Parish.
Local HIV snapshot
Ascension Parish HIV care continuum (2023)
Ascension Parish recorded 10.2 new HIV diagnoses per 100,000 (2023), against 22.5 statewide and 13.7 nationally. Among Ascension Parish residents living with HIV, 85.3% are in care · 81.2% 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 Ascension Parish tests for syphilis.

Data & references
Local context
Most Donaldsonville households own their homes: a majority with roots planted here, and a substantial renting share whose lower monthly costs still leave real trade-offs when work is scarce. With unemployment running notably high and only about half the adult population in the labor force, discretionary time and spare cash don't stretch far. That economic texture shapes something practical: when getting tested means arranging a ride out along Highway 1 South or Marchand Drive in a city where walking to a clinic isn't realistic, it's easy for screening to drift. That matters most for the younger adults here, people in their late teens through early thirties, who are statistically most likely to encounter chlamydia, gonorrhea, or syphilis and least likely to have established primary-care relationships.
With average households running large and a relatively low share of married adults, many in that group are navigating relationships and new partners without the kind of built-in health-care prompts that come with stable family coverage or a regular doctor. Ascension Parish's STI numbers give this local context real weight. The testing options listed here, several with sliding-scale fees, mean that cost and distance, while genuinely real considerations in Donaldsonville, don't have to be the final word. Someone finishing a shift, catching a ride past Louisiana Square, can find a same-week appointment without rearranging their life.

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