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.

People look up STD rates for many reasons. Some want to understand how common infections are in their borough. Others are comparing std rates by state or std rates by city before a move, a new relationship or a conversation with a partner. Whatever brings you here, numbers are most useful when you know where they come from and what they can and cannot tell you.

This guide walks through the most recent figures published for New York City and New York State, explains how to read them, and points to free and low-cost testing across the five boroughs. Every number below is named with its year and its source.

Key takeaways

The NYC Department of Health and Mental Hygiene (DOHMH) reported 62,774 chlamydia cases in 2024, a rate of 760.16 per 100,000 people.
NYC DOHMH reported 32,889 gonorrhea cases in 2024, a rate of 398.27 per 100,000.

How to read STD rates

A rate is a count of reported cases divided by the number of people in a place, then scaled to 100,000. This lets a city of more than eight million be set beside a smaller county or a whole state without the biggest place always looking worst.

Rates still have limits. Keep these in mind as you read.

Reported cases are not every infection

Surveillance counts only infections that were tested for, found and reported. Many chlamydia and gonorrhea infections cause no symptoms, so the CDC STI Treatment Guidelines (2021) stress screening for people who may be at risk. A place with more screening will find and report more infections, and that is a sign of looking, not necessarily of more spread.

Different years and different sources

The NYC DOHMH publishes its own annual STI report. The CDC publishes state ranking tables with a lag of a year or more. When you search for std rates by state, you will usually see CDC tables for an earlier year than the city report. That gap matters, and it is why this guide keeps city and state numbers in separate tables.

A rate describes a place, not a person

A citywide rate cannot say whether any one person has an infection. Only a test and a clinician can do that. If you are wondering about your own health, testing is the way to find out.

NYC DOHMH noted that its 2023 and 2024 rates were both calculated using 2023 population estimates. It also noted that figures for 2025 in the report are preliminary and cover only part of the year, so this guide does not use them.

The latest New York City figures

The most recent full-year figures come from the NYC DOHMH STI Surveillance Annual Report for 2024 and the NYC DOHMH HIV Surveillance Annual Report for 2024. They cover all five boroughs: Manhattan, Brooklyn, Queens, the Bronx and Staten Island.

Infection	Reported cases, 2024	Rate per 100,000, 2024	Source
Chlamydia	62,774	760.16	NYC DOHMH STI Surveillance Annual Report, 2024
Gonorrhea	32,889	398.27	NYC DOHMH STI Surveillance Annual Report, 2024
Primary and secondary syphilis	1,467	17.76	NYC DOHMH STI Surveillance Annual Report, 2024
Early latent syphilis	2,842	34.41	NYC DOHMH STI Surveillance Annual Report, 2024
Congenital syphilis	37	43.18 per 100,000 live births	NYC DOHMH STI Surveillance Annual Report, 2024
New HIV diagnoses	1,791	Citywide rate not stated in the one-page summary	NYC DOHMH HIV Surveillance Annual Report one-pager, 2024

Chlamydia

Chlamydia is the most commonly reported infection in the city. The NYC DOHMH counted 62,774 cases in 2024, or 760.16 per 100,000 residents. Chlamydia is a bacterial infection, and the CDC says it is curable with treatment from a clinician. Because it often has no symptoms, testing is the only way to know.

Gonorrhea

The NYC DOHMH reported 32,889 gonorrhea cases in 2024, a rate of 398.27 per 100,000. Gonorrhea is also bacterial and curable with treatment from a clinician. The CDC recommends that a clinician choose treatment, because the right choice depends on the person and the site of infection.

Syphilis

Syphilis is counted by stage. In 2024 the NYC DOHMH reported 1,467 primary and secondary cases (17.76 per 100,000) and 2,842 early latent cases (34.41 per 100,000). Early latent means the infection has no symptoms but was acquired within the past year. Syphilis is curable with treatment from a clinician, and earlier treatment protects long-term health.

Congenital syphilis

Congenital syphilis happens when syphilis passes from a pregnant person to a baby. The NYC DOHMH counted 37 cases in 2024, or 43.18 per 100,000 live births. Each of these cases is preventable with screening and treatment during pregnancy, which is why New York has specific testing rules, described below.

HIV

The NYC DOHMH reported 1,791 new HIV diagnoses in 2024. The one-page summary does not state a citywide rate per 100,000, so this guide does not give one. HIV is not curable, but it is treatable. A clinician can prescribe medicine that lets people with HIV stay healthy, and the CDC says that treatment that keeps the virus at very low levels also prevents sexual transmission.

What about year-on-year change?

Year-on-year change is best read straight from the annual report, which includes trend tables across several years. This guide does not quote a percentage change, because the pages used here give the 2024 counts and rates but not a verified comparison with 2023 that fits this format. For trends, open the NYC DOHMH STI Surveillance Annual Report linked in the sources below, or check with the health department.

New York State figures and how they compare

Most people who search for std rates by state want to know how New York sits among states. The CDC publishes state ranking tables each year. The most recent set used here is the CDC 2023 STI Surveillance State Ranking Tables, so the year is 2023, not 2024.

Infection	New York State, 2023	CDC table position	Source
Chlamydia	558.4 per 100,000 (109,284 cases)	Rank 10 (Table 28)	CDC 2023 STI Surveillance State Ranking Tables
Gonorrhea	235.6 per 100,000 (46,102 cases)	Rank 7 (Table 19)	CDC 2023 STI Surveillance State Ranking Tables
Primary and secondary syphilis	14.8 per 100,000 (2,887 cases)	Rank 25 (Table 9)	CDC 2023 STI Surveillance State Ranking Tables
Congenital syphilis	32.2 per 100,000 live births (67 cases)	Rank 40 (Table 4)	CDC 2023 STI Surveillance State Ranking Tables
New HIV diagnoses	2,555 (count), 2024	Not ranked here	NYS Department of Health, New York State HIV At a Glance 2024

Why the city and state numbers do not line up

It is tempting to compare the city rate of 760.16 for chlamydia with the state rate of 558.4. Please do not. The city number is for 2024 and comes from the NYC DOHMH. The state number is for 2023 and comes from the CDC. Different years, different sources and different population estimates all affect the result.

What can be said safely is that both sources show chlamydia as the most commonly reported infection, with gonorrhea next, and syphilis and HIV reported in smaller counts. The state HIV count of 2,555 new diagnoses in 2024 includes the city's 1,791, so a large share of the state total is reported in New York City.

Using std rates by city responsibly

Searches for std rates by city often turn up lists that put one city above another. Those lists mix years, definitions and testing levels. A city with more screening can look higher, and a city with less screening can look lower even when the real picture is the same. If you want to compare places, use the same source and the same year for each, such as the CDC state tables above, and read the notes that come with them.

What shapes the numbers

No single factor explains the figures. The CDC and the NYC Health Department point to a mix of things that affect both how many infections occur and how many are found.

How much testing happens

More testing means more infections are found and reported. This is especially true for chlamydia and gonorrhea, where many infections have no symptoms. A high count can partly reflect strong screening, and the CDC STI Treatment Guidelines (2021) support regular screening for people who may be at higher risk.

Access to care

People who cannot easily reach a clinic may go longer without a test or treatment. Cost, work hours, transportation, language and fear of being judged can all get in the way. Free and low-cost walk-in clinics, described below, exist to lower those barriers.

Reinfection and partner treatment

A person treated for a bacterial infection can be infected again if a partner is not treated. New York law allows expedited partner therapy (N.Y. Public Health Law § 2312), which lets a clinician provide treatment for a patient's partner in certain cases. NYC Health says the infections for which the CDC recommends this approach are chlamydia, gonorrhea and trichomoniasis. Ask a clinician whether it applies to you.

Population and geography

New York City is dense, mobile and diverse. Rates can differ widely between neighborhoods and boroughs, and the full NYC DOHMH report breaks them down further than this guide does. A citywide figure hides those differences.

Prevention tools

Prevention has expanded. PrEP can lower the chance of getting HIV, and the CDC issued guidance in 2024 on doxycycline post-exposure prophylaxis (doxy-PEP), which a clinician can prescribe to some people to lower the chance of certain bacterial infections after sex. Whether either is a fit for you is a conversation for a clinician.

Syphilis in pregnancy, reporting and privacy

Required syphilis tests during pregnancy

The New York State Department of Health says providers must test pregnant people for syphilis at least three times: at the first prenatal visit, in the third trimester, and at delivery. A May 2024 letter from the department sets the third-trimester test at 28 weeks, or as soon after as reasonably possible, and no later than 32 weeks. The NYC Health Code (§ 11.33) separately requires physicians in the city to draw blood for syphilis testing on the same schedule.

These rules exist because syphilis in pregnancy is treatable, and treatment can protect the baby. If you are pregnant or planning to be, ask your clinician about the timing of your tests.

What gets reported to the health department

The NYC Health Code requires certain infections, including chlamydia, gonorrhea and syphilis at all stages, to be reported to the Health Department within 24 hours, according to NYC Health. Under N.Y. Public Health Law § 2130, physicians and laboratories must also report HIV infection to the state health commissioner. Reporting is how the counts in this guide exist. Case reports are used for public health work such as follow-up and planning, and the reader can ask the clinic how their information is handled.

Testing as a young person

New York Public Health Law § 2305 allows a licensed physician to diagnose and treat a person under 21 who has or may have been exposed to an STD without a parent's consent. NYC Health says its Sexual Health Clinics serve anyone 12 or older without parental consent, regardless of immigration status.

Free and low-cost testing in the five boroughs

The point of looking at rates is to act on them. If a test is on your mind, the city makes that easier than many people expect. You can find a longer walkthrough on our page about where to get tested in New York City, and a shorter list of clinics on the home page.

NYC Health Sexual Health Clinics

The NYC Health Department runs Sexual Health Clinics that offer STI testing, HIV testing, PrEP, PEP, doxy-PEP, HPV vaccine (for patients receiving other sexual health services) and treatment. NYC Health says services are low-cost or no-cost. Adults 19 and older are asked for insurance or a sliding-scale fee, no proof of income is required, no payment is collected at the clinic, and no one is turned away for inability to pay. Most services are walk-in, and clinics may close early once they reach capacity, so arriving early is wise.

The clinic hotline is 347-396-7959 (Monday to Friday, 9 a.m. to 3:30 p.m.). The 24/7 PEP Hotline is 844-373-7692. NYC Health does not list a separate number for each clinic.

Chelsea Sexual Health Clinic and Chelsea Express Clinic, 303 9th Avenue, First Floor, Manhattan, NY 10001. Open Monday to Friday, 8:30 a.m. to 3:30 p.m. The main clinic does not offer rapid results, and NYC Health says to expect results in seven days. The Express Clinic has a Quickie Lab with rapid chlamydia and gonorrhea results and is open Monday and Wednesday to Friday, 8:30 to 3:30, and Tuesday 8:30 a.m. to 7 p.m.
Central Harlem Sexual Health Clinic, 2238 Fifth Avenue, First Floor, Manhattan, NY 10037. Monday to Friday, 8:30 a.m. to 3:30 p.m.
Fort Greene Sexual Health Clinic and Express Clinic, 295 Flatbush Avenue Extension, Brooklyn, NY 11201. The clinic is on the second floor and the Express Clinic on the first. Hours match Chelsea, including the Quickie Lab for rapid chlamydia and gonorrhea results.
Morrisania Sexual Health Clinic, 1309 Fulton Avenue, Second Floor, Bronx, NY 10456. Monday to Friday, 8:30 a.m. to 3:30 p.m.
Jamaica Sexual Health Clinic, 90-37 Parsons Boulevard, First Floor, Queens, NY 11432. Monday to Friday, 8:30 a.m. to 3:30 p.m.
Corona Sexual Health Clinic, 34-33 Junction Boulevard, First Floor, Queens, NY 11372. Monday to Wednesday and Friday, 8:30 a.m. to 3:30 p.m., and Thursday, 8:30 a.m. to 7:15 p.m.

NYC Health says the Crown Heights (Brooklyn) and Riverside (Manhattan) clinics are closed until further notice, and its open list includes no Sexual Health Clinic on Staten Island. Staten Island residents can check with the health department for the nearest option. Hours and locations can change, so confirm on the NYC Health Sexual Health Clinics page before you go.

Callen-Lorde Community Health Center

Callen-Lorde is an LGBTQ+ community health center that offers STI testing, HIV testing, PrEP, PEP, doxy-PEP, HPV vaccine, hepatitis C testing and treatment. Its Chelsea site is at 356 W 18th St, New York, NY 10011, phone 212-271-7200. Sexual health visits are by appointment Monday to Friday with limited walk-in, and Saturday 9 a.m. to 3 p.m. is walk-in, first come first served. Callen-Lorde says it serves people regardless of ability to pay, with a sliding fee for people who are uninsured or underinsured and visit co-pays from $0 to $100. It also lists a Bronx site (555 Bergen Ave, 4th floor, 718-215-1800) and a Brooklyn site (40 Flatbush Ave Ext, 3rd floor, 718-215-1818). Its sexual health page names only the Chelsea site, so ask which services each location offers.

Mount Sinai Adolescent Health Center

For people ages 10 to 26, the Mount Sinai Adolescent Health Center at 312-320 East 94th Street, New York, NY 10128 (212-423-3000) says its services are completely free. It lists walk-in hours Monday to Saturday, 8:30 a.m. to 4 p.m., along with scheduled appointments, STI screening and treatment, and HIV testing with same-day rapid results.

Paying for PrEP-related care

The New York State PrEP Assistance Program (PrEP-AP) helps people who are uninsured, or whose insurance does not cover some PrEP services, pay for PrEP-related health care and lab costs. It does not cover the medication itself, which can come through manufacturer assistance. The program number is 1-800-542-2437, and you must use a participating provider. NYC Health also says its clinics offer PrEP starts and counseling, and that adolescents can get PrEP without a parent's permission.

Free HIV self-test kits

NYC Health says residents can get free HIV self-test kits from Community Home Test Giveaway partner agencies listed on the NYC Health Map, through 311, or by texting TESTNYC to 55676. NYC Health pages do not list a free at-home STI kit program, so for chlamydia, gonorrhea and syphilis, a clinic visit is the route.

Finding other sites

The CDC runs a national locator at gettested.cdc.gov where you can enter a ZIP code to find nearby testing sites. Call ahead to ask about cost, hours and which tests are offered.

Prevention, treatment and common questions

What treatment looks like

Chlamydia, gonorrhea, syphilis and trichomoniasis are curable with treatment from a clinician. HIV, herpes and HPV are not curable, but they are treatable or manageable, and a clinician can explain the options. The right treatment depends on the infection, your health history and your test results, so it is always chosen by a clinician.

How often should someone test?

The CDC STI Treatment Guidelines (2021) and the U.S. Preventive Services Task Force (USPSTF) set screening advice by age, pregnancy status and risk. A clinician can tell you which tests fit your situation and how often to repeat them. A recent test may also need repeating, since some infections do not show up right away. Ask the clinician for the timing that fits your exposure.

Do high rates mean I should worry?

No. Rates describe a population, and they say nothing about you. The useful response to a number is practical: know your options, get tested if you have reason to, and talk with partners. Anyone who is sexually active, whatever their gender or orientation, can have an infection and benefit from a test.

What if a test finds something?

A positive result is a medical finding, and clinicians handle it every day. For curable infections, treatment from a clinician clears them. For HIV, herpes and HPV, a clinician can set up ongoing care. The clinic can also talk with you about telling partners, including anonymously through the health department if you prefer.

Can I get the numbers for my borough?

Yes. The full NYC DOHMH STI Surveillance Annual Report for 2024 contains more detail than a citywide rate. For anything this guide does not cover, check with the NYC Department of Health and Mental Hygiene.

Where to go next

Rates are one lens on sexual health. Testing, treatment and prevention are where they turn into action. If a test is on your list, our guide to STD testing in New York City covers what to expect at a visit, and the clinics above are a good first call.
