This page is general health information, not medical advice. It cannot tell you whether you have an infection. A clinician can, and the testing options on this site are a good place to start.

Numbers about sexually transmitted infections can feel abstract. This guide puts them in context for Miami. It covers the newest published figures for Miami-Dade County and Florida, how to read STD rates by state and STD rates by city, and what the data does and does not explain. It ends with where to get free or low-cost testing.

Rates describe populations, not individuals. They say nothing about whether any one person has an infection. Only a test and a clinician can do that.

Key Takeaways

In 2025, Miami-Dade County reported 471.5 chlamydia cases per 100,000 people, compared with 410.8 statewide (FLHealthCHARTS, Florida Department of Health).
The county's 2025 gonorrhea rate was 250.5 per 100,000, against 156.5 for Florida (FLHealthCHARTS).
Infectious (primary and secondary) syphilis was 16.8 per 100,000 in the county and 12.4 in Florida in 2025 (FLHealthCHARTS).
New HIV diagnoses in 2025 were 23.7 per 100,000 in Miami-Dade and 15.0 in Florida (FLHealthCHARTS).
Reported rates reflect both infections and how much testing happens. A higher rate is a reason for testing access, not for stigma.
Free and low-cost testing exists in Miami. Check with each clinic for current hours and fees.

How to Read STD Rates by State and by City

Most people searching for STD rates by city want one number to compare with another place. That is a fair goal, but a few details decide whether a comparison is meaningful.

Rates versus case counts

A case count is the number of reported infections. A rate divides that count by the population, usually per 100,000 people. Rates let you compare a large county with a small one. A big place will almost always have more cases, so counts alone mislead.

County, city and state are different lenses

Public health agencies report most STI data by county. The figures in this guide are for Miami-Dade County, which includes the City of Miami and many other municipalities. They are not a count for the city limits alone. If you need a narrower area, the Florida Department of Health publishes its data tools on FLHealthCHARTS, and the Florida Department of Health in Miami-Dade County can say what is available.

Different sources, different years

This guide uses two kinds of sources. FLHealthCHARTS, run by the Florida Department of Health, has the newest county and state figures (2025). The CDC's state ranking tables are from its 2023 STI surveillance report, which is the latest CDC state-level data. The CDC has said its 2024 report was provisional and national only. Because the years and methods differ, do not subtract one source from the other. Compare county to state within the same source and year.

Reported cases are not all infections

The CDC notes that many STIs cause no symptoms, so many infections are never found or reported. Reported rates therefore depend on how many people get tested as well as on how many are infected. Places with more testing can show higher rates simply because more infections are being found.

Chlamydia and Gonorrhea in Miami-Dade

Chlamydia and gonorrhea are bacterial infections. The CDC STI Treatment Guidelines (2021) describe both as curable with treatment from a clinician. They are also two of the most commonly reported infections, which makes them useful indicators.

Chlamydia

FLHealthCHARTS, from the Florida Department of Health, reports the following for 2025:

Miami-Dade County: 471.5 cases per 100,000 people (13,271 cases).
Florida: 410.8 cases per 100,000 people (96,044 cases).

The county rate is roughly 15 percent higher than the statewide rate. For a separate view, the CDC's 2023 STI Surveillance state ranking tables list Florida at 498.9 chlamydia cases per 100,000 (112,804 cases), rank 17 in that table.

The CDC's 2023 and the state's 2025 Florida figures are not the same number, because they come from different years and sources. Both are accurate descriptions of what each source reported.

Gonorrhea

FLHealthCHARTS reports these gonorrhea figures for 2025:

Miami-Dade County: 250.5 cases per 100,000 people (7,052 cases).
Florida: 156.5 cases per 100,000 people (36,596 cases).

Here the gap is larger. The county rate is about 60 percent above the statewide rate. In the CDC's 2023 state ranking tables, Florida's gonorrhea rate was 206.7 per 100,000 (46,726 cases), rank 11.

Why these two matter for testing

The CDC STI Treatment Guidelines (2021) note that chlamydia and gonorrhea are often silent. Without symptoms, testing is the only way to find out. Both can be treated by a clinician once found. Both are also on Florida's list of reportable conditions, which is why the counts above exist.

Infection (2025, FLHealthCHARTS)	Miami-Dade rate per 100,000	Florida rate per 100,000
Chlamydia	471.5 (13,271 cases)	410.8 (96,044 cases)
Gonorrhea	250.5 (7,052 cases)	156.5 (36,596 cases)

Syphilis in Miami-Dade and Florida

Syphilis is a bacterial infection that the CDC STI Treatment Guidelines (2021) describe as curable with treatment from a clinician. It moves through stages, and the figures below describe the infectious stages that are reported together.

Infectious syphilis, 2025

FLHealthCHARTS defines infectious syphilis as primary plus secondary syphilis. For 2025 it reports:

Miami-Dade County: 16.8 per 100,000 people (472 cases).
Florida: 12.4 per 100,000 people (2,903 cases).

The county rate is about 35 percent above the statewide figure. The Florida Department of Health counts syphilis in pregnant women and newborns as reportable too.

The CDC's state view

In the CDC's 2023 STI Surveillance state ranking tables, Florida's primary and secondary syphilis rate was 19.3 per 100,000 (4,366 cases), rank 16. The same CDC tables list congenital syphilis in Florida at 104.7 per 100,000 live births (235 cases), rank 17.

Congenital syphilis is syphilis passed from a pregnant person to a baby. The CDC treats it as preventable with timely testing and treatment during pregnancy. That is why Florida rules require prenatal testing, covered in the section on Florida rules below.

A note on comparing the numbers

The state-level syphilis figure from FLHealthCHARTS (12.4, year 2025) and from the CDC (19.3, year 2023) are different. They come from different years and reporting systems, and the CDC row specifically reports primary and secondary stages. Use each in its own context.

HIV Diagnoses in Miami-Dade and Florida

HIV is not curable, but it is treatable. The CDC describes modern HIV treatment as helping people with HIV stay healthy for many years. The numbers below count new diagnoses, which means people who received an HIV diagnosis in that year. A diagnosis in 2025 does not always mean the infection happened in 2025.

New diagnoses, 2025

FLHealthCHARTS, HIV Diagnoses, with data as of June 30, 2026, reports:

Miami-Dade County: 23.7 per 100,000 people (668 diagnoses).
Florida: 15.0 per 100,000 people (3,512 diagnoses).

The county rate is roughly 58 percent above the statewide rate.

Year-on-year change

For the state, FLHealthCHARTS lists 4,398 diagnoses in 2024 (19.1 per 100,000) and 3,512 in 2025 (15.0 per 100,000). That is a lower number in the later year.

The page does not explain the decline, and it does not flag the 2025 figure as provisional. This guide does not offer a reason for it either. A change in a single year can come from many things, including testing patterns and how quickly diagnoses are reported. County figures for 2024 were not part of the material reviewed, so a county year-on-year comparison is not shown here.

Prevention and testing options

PrEP and PEP are medicines a clinician prescribes to lower the chance of getting HIV. The Florida Department of Health in Miami-Dade County links to a PrEP and nPEP provider locator from its HIV/AIDS page, described as a way to find locations that can provide pre and post-exposure prophylaxis. It also lists a PrEP Workgroup where community members and providers coordinate PrEP and nPEP services. A clinician decides whether either is appropriate for a given person.

What Drives the Numbers

It is natural to ask why a county's rate is higher or lower than the state's. The honest answer is that the published figures describe what happened, not why. The sources this guide relies on do not attribute Miami-Dade's rates to a cause, so this section sticks to what public health agencies do say about how to read them.

Testing volume

Because many STIs have no symptoms, the CDC says the number of reported cases depends in part on how much screening occurs. More screening finds more infections. A high rate can partly reflect an active testing system.

Who gets reported

Florida requires practitioners, hospitals and labs to report certain conditions to the Department of Health. Under Florida Administrative Code Rule 64D-3.029, chlamydia, gonorrhea, syphilis and HIV are on that list. Reporting completeness can differ from place to place and year to year.

Population and mix of people

Miami-Dade is a large, dense, international county with many visitors. Rates are adjusted for population size but not for how many visitors, residents or people in different age groups are present. Age matters because the CDC reports that STIs are diagnosed most often in younger adults. This guide does not have county age breakdowns, so it cannot say how age shapes the local figures.

What the data cannot say

The rates cannot tell any individual whether they have an infection. They also cannot support claims about any group of people. STIs affect people of every gender, orientation, age and background. Anyone who is sexually active can benefit from a conversation with a clinician about what testing fits their situation. The CDC STI Treatment Guidelines (2021) and USPSTF recommendations lay out who is generally advised to be screened and how often.

Florida Rules That Shape Testing and Reporting

Florida law affects both how the numbers are produced and how people can use services. Here are the parts most relevant to readers in Miami.

Minors can consent to testing and treatment

Under Florida Statutes section 384.30, the Florida Legislature's Online Sunshine site states that any minor may consent to examination and treatment for sexually transmissible diseases. The statute sets no minimum age. A minor's consultation, examination and treatment are confidential, and the law bars disclosure directly or indirectly, for example by billing a parent or guardian, except as provided in section 384.29. The statute applies to the Department of Health, licensed physicians and certain other licensed professionals, and qualified public or private health facilities. If you have questions about how a particular clinic handles billing, ask the clinic.

Prenatal testing

Florida Administrative Code Rule 64D-3.042 says practitioners providing prenatal care must test for chlamydia, gonorrhea, hepatitis B, HIV and syphilis at the first exam for the pregnancy and again at 28 to 32 weeks. A person may refuse in writing. People who arrive at delivery with no prenatal care, no record of testing, or no testing after the 27th week must be tested for hepatitis B surface antigen, HIV and syphilis before discharge. Anyone with a reactive syphilis test during pregnancy must be tested as soon as possible at or after delivery. The rule does not require universal syphilis testing for everyone at delivery.

Treating partners

The CDC's page on the legal status of expedited partner therapy in Florida says Florida law (section 384.27) allows a clinician, under certain conditions, to provide treatment for a patient's partner without examining the partner first. The conditions include a lab-confirmed or suspected clinical diagnosis, a patient report of sexual activity with the partner, and a partner who is unable or unlikely to seek care in a timely way. Pharmacists may dispense these prescriptions. Whether this applies is a clinician's decision.

Reporting

Under section 381.0031(2) of the Florida Statutes, practitioners, hospitals and labs must report diseases of public health significance to the Department of Health. This is how the rates in this guide are built.

Free and Low-Cost Testing in Miami

Rates are the backdrop. Testing is the action. Here are the options published by the health department and by clinics. Hours and fees can change, so confirm with the clinic before you go. For a fuller local list with costs, see our guide to where to get tested in Miami and what it costs.

Florida Department of Health in Miami-Dade County

The Department of Health's STI page says, "We offer low or no-cost testing for chlamydia, gonorrhea, syphilis, and HIV." Its HIV Prevention page says it provides free prevention education and testing for HIV, chlamydia, gonorrhea and syphilis. The two pages use different wording, so ask the clinic what applies to your visit. The page does not publish a fee schedule.

Health District Center (STI clinic): 1350 NW 14th St., Suite 350, Miami, FL 33125. Listed hours are Monday to Friday, 8 a.m. to 3:30 p.m., closing at noon on the 1st and 3rd Fridays.
West Perrine Health Center (STI clinic): 18255 Homestead Ave., Miami, FL 33157. Listed hours are Tuesday, Thursday and Friday, 8 a.m. to 3:30 p.m., closing at noon on 3rd Fridays.
Scheduling: the page lists 305-575-3800 for appointments at both sites. It does not state a walk-in policy, so call first.
Disease control line: 305-470-5660 is listed on the STI page. The HIV testing line is 786-792-5269.

Community health centers and other options

Care Resource, Midtown Miami: 3510 Biscayne Blvd., Miami, FL 33137, phone 305-576-1234. CDC GetTested lists free HIV and STI testing with no appointment required.

Testing hours are listed as Monday to Friday, 8:15 a.m. to 4:30 p.m.
Care Resource, Little Havana: 1800 S.W. 1st Street, Miami, FL 33135, phone 305-576-1234. Its page describes no-cost rapid HIV testing and wellness screenings. The pages reviewed do not state STI testing for this site.
Borinquen Medical Centers, Main Office: 3601 Federal Hwy, Miami, FL 33137, phone 305-576-6611. CDC GetTested lists HIV and STI tests as free with no appointment required, and it lists insurance, Medicaid, Medicare and a sliding scale.
Jessie Trice Community Health System, Main Center: 5361 NW 22nd Ave, Miami, FL 33147, phone 305-637-6400. CDC GetTested lists insurance, Medicaid, Medicare and a sliding scale, with no free services listed. It lists HIV, chlamydia and gonorrhea tests and does not list syphilis for this site. No appointment is required per that listing.
UM Rapid Access Wellness Clinic and PrEP Program: 1120 NW 14th St, Miami, FL 33136, phone 305-243-2584. CDC GetTested lists HIV, hepatitis B, hepatitis C and STI tests as free and says an appointment is required.
Pridelines (Thrivelines Health), Miami Beach: 1130 Washington Ave, First Floor, Miami Beach, FL 33139, phone 305-571-9601. This is in the City of Miami Beach, not the City of Miami. Its Thrivelines page describes HIV testing as fast, free and confidential and says it also does mobile testing across Miami-Dade, Broward and Monroe counties.

Free HIV tests at home

The Department of Health in Miami-Dade offers a free HIV home test kit to Miami-Dade County residents only. Care Resource lists a no-cost HIV home test for people ages 14 and older who live in Miami-Dade or Broward, are not HIV-positive, and have not tested in the last three months. It can be ordered online or at 305-576-1234, extension 352. The CDC also points to Together TakeMeHome, a national program for free HIV self-tests by mail. A clinician can explain what any result means and what follow-up testing is needed.

Finding more places

The CDC's GetTested locator lists testing sites by ZIP code, with services and cost details as submitted by each site. Because the CDC notes that listings can change, confirm hours with the clinic.

Next Steps

Numbers about Miami can look large, but they point to something practical. Testing is available, often at low or no cost, and the common bacterial infections can be cured by a clinician once found. HIV is manageable with treatment, and prevention medicines exist.

Choose a clinic from the list above and call to confirm hours, cost and whether you need an appointment.
Ask the clinician which tests fit your situation. The CDC STI Treatment Guidelines (2021) and USPSTF recommendations guide those choices.
If you are pregnant or planning a pregnancy, ask your prenatal provider about the testing Florida rules call for.
If you want to learn about PrEP or PEP, use the Department of Health's provider locator or ask a clinic that offers it.

Rates will keep changing as new data comes in. The best way to stay current is to check FLHealthCHARTS and the Florida Department of Health in Miami-Dade County directly.
