STD stats & rates
How reported STI rates in Putnam County, the county that includes Worthington, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data.
#108 of 115 Missouri counties for chlamydia, a higher rate than 6% of the state
| Infection | Putnam County | Missouri | United States |
|---|---|---|---|
| Chlamydia | 86.2 4 cases ▼ 83% | 498.6 | 492.2 |
| Gonorrhea | — no data | 201.9 | 179.5 |
| Syphilis (P&S) | — no data | 21.5 | 15.8 |

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 Putnam County, chlamydia has fallen from 213.6 to 86.2 per 100,000 (60%), and gonorrhea has held roughly steady from 42.9 to 42.9 per 100,000.
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Putnam County.

Federal priority area: Missouri is one of the U.S. jurisdictions prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
Putnam County HIV care continuum (2023)
Putnam County recorded 0 new HIV diagnoses per 100,000 (2023), against 10.6 statewide and 13.7 nationally. 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 Putnam County tests for syphilis.

Data & references
Local context
Worthington's name reflects the settlers who built here, and that same spirit of self-reliance runs through how residents approach their health today. Young adults in town, a notably present age group, often seek STI testing quietly and on their own terms, without fanfare or the sense that word will travel. Testing in and around Worthington is available through clinics listed on this page, each offering the confidentiality that matters when you're managing your sexual health in a place where many people have known you for years. The clinics serving Worthington understand that discretion isn't theatrical here; it's practical.
Staff respect the reality that some conversations don't belong in a waiting room where you might run into an acquaintance, and test results are handled with the straightforwardness you'd expect from healthcare providers who know their community well enough not to gossip about it. Whether you're between jobs, settling into a new relationship, or simply staying current with routine screening, the testing available locally removes one barrier: you won't have to travel far or explain yourself to a stranger. Results arrive within the timeframe each clinic provides, and from there, your next steps are yours alone.

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