In the state of Florida and much of the rest of the U.S., the prevalence of sexually transmitted diseases (STDs), often referred to as sexually transmitted infections, is on the rise. According to the CDC’s most recent reporting, rate of three of the most common infections (chlamydia, gonorrhea and syphilis) rose in 2017, marking the fourth straight year of increases for all three STDs. Florida’s health data largely mirrors these increases.

Which STDs are most prevalent in the state of Florida, which areas of the state have the highest concentrations of infections and how has the picture of sexual health changed in our state over time? Let’s take a close look at data from the federal Centers for Disease Control and Prevention and the Florida Department of Health.

Chlamydia Rates in Florida

Chlamydia infections in Florida in 2017 topped 100,000, putting the state fourth in terms of overall number of cases. But when adjusted for population, Florida falls out of the top 25, and the state has a rate lower than the national infection rate.

HIV & Other STD Rates in Florida

HIV

Nearly 5,000 people were newly diagnosed with HIV in our state in 2017, a slight increase from 2016, putting the state at the very top of the list in terms of overall cases. Even when adjusted for population, Florida has one of the highest rates of HIV infections in the country (22.9 per 100,000), coming in second behind Georgia (24.9 per 100,000). The state’s infection rate stayed level between 2016 and 2017. See also HIV test options.

Hepatitis B & C

Florida ranks fifth overall in the nation for acute hepatitis B infections with a rate nearly three times higher than the national rate (2.7 per 100,000 vs. 1 per 100,000). Acute hep C infections are a bit less common in our state, but Florida’s population-adjusted rate is still slightly higher than the national rate (1.1 per 100,000 vs. 1 per 100,000). Rates of both infections have risen by at least two-thirds since 2012. See also hepatitis test options.

HPV

Human papillomavirus is the most common STD, but the vast majority who have it aren’t aware, which encourages the disease to spread easily. Precise figures on the number of Floridians who catch HPV each year are unavailable, but we do know that Florida has one of the highest rates of HPV-related cancers of any state, and HPV is the major cause of cancers in several parts of the body, including the cervix, penis, anus and vulva. Florida’s rate of HPV-related cancer is fourth-highest in the country at 14.3 per 100,000. See also HPV test options.

STDs in Florida Cities & Counties

STD rates vary pretty widely across the state of Florida, which contains several large and medium metro areas, including Fort Lauderdale, Jacksonville, Miami and Orlando.

Chlamydia

Miami accounted for 12% of all chlamydia cases in 2017, but Miami-Dade County’s chlamydia rate is not among the top 10 in the state.

Conclusion

Sexually transmitted infections are incredibly common across the United States and right here in Florida. People who are concerned they could have an STD often put off getting tested out of embarrassment or fear of finding out they have a serious condition. There’s no doubt some STDs are very dangerous, but almost all of them can be treated and the ones that can’t be treated can often be prevented with medication. But it’s important to take the first step and find out your STD status by getting tested.

Additional References

Note: The CDC publishes comprehensive STD data on only three of the many conditions that are sexually transmitted — chlamydia, gonorrhea, and primary and secondary syphilis. Many other STDs are not classified as nationally notifiable diseases, meaning states are not legally obligated to report infection rates. Also, while the CDC collects data for the District of Columbia, the population density of the district prevents it from being included in rankings.
