These states have the highest and lowest STD rates

Our research team dives deep into the C.D.C.’s latest 2019 STD Surveillance Statistics and provides our analysis of current trends.

The Centers for Disease Control and Prevention (C.D.C.) recently released its latest Sexually Transmitted Disease Surveillance Report (Oct., 2019) along with new data on the number of reported sexually transmitted disease (STD) cases across the United States. Innerbody.com’s research team analyzed and combined the latest statistics developed our annual state rankings by STD rate from highest to lowest along with key trends.

Before we get to the rankings, here are some findings and trends that we observed:

American southern states continue to dominate our state rankings with alarmingly high STD rates. In fact, 7 out of the Top 10 states are in the South.

What is going on in the South? According to Ronald Gray, MD, a professor of epidemiology at John Hopkins, the answer may simply come down to lack of access to affordable health care. “The South has more people living in poverty and in rural areas,” he says, “which may make it harder for them to get tested and treated for STDs.”

Unlike Chlamydia and Gonorrhea, Syphilis infection rates appeared to disproportionately affect western states:

State rankings by syphilis (primary and secondary) infection rate:

  1. Nevada (22.7 cases per 100K population)
  2. California (19.2 cases per 100K population)
  3. Mississippi (15.5 cases per 100K population)
  4. Georgia (15.4 cases per 100K population
  5. Arizona (14.9 cases per 100K population)

California led all states with the largest number of cities with high STD rates with seven cities. Ohio and Texas tied for the second most cities, both of which had six each. For more information about how individual U.S. cities stack up, check out our recently published U.S. Cities STD Statistics Rankings and Research.

In terms of total STD cases, as one might expect, the largest states have the most number of reported STD cases.

State rankings by total number of STDs reported:

  1. California (318,214 total cases reported)
  2. Texas (196,279 total cases reported)
  3. New York (159,487 total cases reported)
  4. Florida (140,282 total cases reported)
  5. Illinois (104,155 total cases reported)

Without further ado, below are our rankings of each U.S. state based on STD (highest to lowest):

How We Collected Data for This Report

All of the STD data found in this report, including case statistics for HIV, syphilis, gonorrhea, and chlamydia, are from the C.D.C.’s latest data release (Aug. 2019) for the year 2018. Syphilis data includes only primary and secondary syphilis cases and does not include congenital and early latent syphilis cases. HIV cases are not reported for some cities. Statistics for other relatively common STDs, such as herpes, are not collected by the C.D.C. at this time and hence are left out of our analysis. For more information about which statistics the C.D.C. does and does not track, see its STD Data & Statistics page.

No statistical testing was used during the production of this research.
