Health Care for the Homeless in Casper takes walk-ins for a full STI panel (gonorrhea, chlamydia, syphilis, and rapid or conventional HIV) plus hepatitis A, B, and C and TB, with same-visit treatment for bacterial infections, on a sliding scale that runs to zero.
Health Care for the Homeless tests for hepatitis A, B, and C alongside the standard bacterial and HIV panel. That breadth means a single visit produces a complete picture of bloodborne and liver-affecting infections, so nothing requires a separate appointment elsewhere.

Health Care for the Homeless operates with a fee structure that reaches a floor of zero, not for a subset of services, but across the entire visit. HIV testing, hepatitis panels, TB screening, STI treatment, and substance-use care are all covered under that same structure, with no line items excluded.

Rocky Mountain Infectious Diseases in Casper runs by appointment, so every visit is structured around your actual care needs: HIV, syphilis, gonorrhea, chlamydia, hepatitis B and C, and TB testing, with sliding-scale fees, same-visit treatment for bacterial infections, and services delivered in Spanish.
Many infectious-disease clinics route Spanish-speaking patients through an interpreter line that sits outside the clinical conversation. At Rocky Mountain Infectious Diseases, care (counseling, treatment decisions, follow-up) is delivered directly in Spanish, keeping nothing at arm's length.
Rocky Mountain Infectious Diseases prescribes both PrEP and PEP for HIV prevention, which means ongoing risk reduction is managed by the same clinicians who handle your testing and infectious-disease care. No separate prescription source to coordinate.
A positive hepatitis C test without an on-site treatment pathway means a second appointment, a new provider relationship, and weeks of potential delay during which the virus continues advancing. Rocky Mountain Infectious Diseases closes that gap entirely, diagnosis and full treatment are managed within the same practice in Casper.

STD stats & rates
How reported STI rates in Natrona County, the county that includes Mills, compare with Wyoming and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~19% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#3 of 23 Wyoming counties for chlamydia, among the very highest in the state
| Infection | Natrona County | Wyoming | United States |
|---|---|---|---|
| Chlamydia | 452.8 362 cases ▲ 45% | 313.2 | 492.2 |
| Gonorrhea | 75.1 60 cases ▲ 78% | 42.3 | 179.5 |
| Syphilis (P&S) | 2.5 2 cases ▲ 14% | 2.2 | 15.8 |
| Syphilis (early) | 7.5 6 cases ▲ 295% | 1.9 | 16 |
| Syphilis (late/unknown) | 8.8 7 cases ▲ 73% | 5.1 | 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 Natrona County, chlamydia has fallen from 559.1 to 452.8 per 100,000 (19%), gonorrhea has fallen from 97.6 to 75.1 per 100,000 (23%), and P&S syphilis has fallen from 7.5 to 2.5 per 100,000 (67%).

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 Natrona County.
Local HIV snapshot
Natrona County HIV care continuum (2021)
Natrona County recorded 0 new HIV diagnoses per 100,000 (2021), against 4.2 statewide and 13.7 nationally. Among Natrona County residents living with HIV, 87% are in care · 80.4% 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 Natrona County tests for syphilis.

Data & references
Local context
Winter winds sweep hard across Mills, and the town's modest neighborhoods (Midwest Heights, Paradise Valley, the quieter blocks of Red Buttes Village) settle in for months of cold. Most households here are built to last; people buy, stay put, and raise families in the same place for years. That stability means health routines matter: screening for STIs becomes something you fit into ordinary life, not a crisis decision. A significant population of young adults moves through Mills, and for many in their late teens through thirties, confidential testing is simply part of staying well.
The affordability that draws families to Mills also means clinic visits fit the budget. Testing facilities in and around Mills are listed on this page, each offering the privacy and straightforward care that lets you get results without fanfare. You walk in, get screened, and walk out. No need for elaborate explanations or complicated logistics.
Because people here tend to know their neighbors and their town, discretion matters. The clinics serving Mills understand that confidentiality is not negotiable; what you discuss with a provider stays with that provider, and your results are yours alone to share or keep private.
Getting there

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