In Rhode Island and across the rest of the United States, the rates of several common sexually transmitted diseases are on the rise. In fact, the U.S. has seen four straight years of increases in the rates of chlamydia, gonorrhea, and primary and secondary syphilis, according to data reported by the federal Centers for Disease Control and Prevention.

Which STDs are most common here in Rhode Island, how does our state compare to others in the region and across the nation, what’s the shape of change over time, and which locales in Rhode Island have the highest concentrations of certain sexually transmitted diseases? To answer all those questions, we’ll delve into years’ worth of data reported by the CDC.

Chlamydia Rates in Rhode Island

Rhode Island’s population-adjusted rate of chlamydia infections is 500 per 100,000 people, which places the state at No. 25 among the 50 states. Rhode Island’s rate is about 5% lower than the overall U.S. rate but is nearly double that of the state with the lowest rate, West Virginia, where chlamydia infections occur at a rate of 226.1 per 100,000 people.

No Northeastern state ranks among the 20 states with the highest rates, and only New York has a rate that is higher than the overall U.S. rate. While Rhode Island ranks in the bottom half of the region the state’s rate is more than three times higher than that of Vermont, which has both the lowest rate in the region and the lowest rate in the nation.

Coming in just within the states with the 25 highest syphilis rates, Rhode Island’s population-adjusted syphilis rate of 6.7 per 100,000 is more than 25% lower than the overall national rate and is nearly three times lower than the rate posted by Nevada, which leads the nation. Still Rhode Island’s rate is many times higher than the rate recorded by Wyoming, 0.7 per 100,000, the lowest in the U.S.

HIV & Other STD Rates in Rhode Island


Rhode Island ranks No. 28 for the population-adjusted rate of HIV diagnoses. In 2017, more than 80 people were newly diagnosed with HIV here in Rhode Island, a rate of 7.8 per 100,000. While the state isn’t yet in the top half of the country for HIV cases, Rhode Island did see a 20% increase in HIV prevalence from the 2016 rate. See How to Test for HIV

Hepatitis B & C

Rhode Island has not reported its rates for acute infections of hepatitis B or hepatitis C. Nationally, both viral infections occur at a rate of about 1 per 100,000 people, while hep C rates have climbed steadily since 2012 but hep B rates have fallen in that time. See How to Test for Hepatitis


Rhode Island has higher-than-median rates of HPV-caused cancer cases. In Rhode Island, such cancers occur at a rate of 12 per 100,000, while they happen nationally at a median rate of 11.7 per 100,000. Human papillomavirus (HPV) causes the vast majority of cases of several types of cancer, most famously cervical cancer. As the world’s most common STD, the virus is usually not harmful, but examining HPV-caused cancer can help provide a window into how serious untreated HPV is in a state. See How to Test for HPV

STDs in Rhode Island Cities & Counties

While Rhode Island has STD rates that tend to be lower than overall national rates, some areas of the state have much higher rates.


Providence County had by far the highest chlamydia rates in the state, accounting for nearly 3 in 4 cases.

Rhode Island’s position when it comes to how common sexually transmitted diseases are here is generally that the state ranks toward the middle of the country, which means some states have it worse, while a few others have it much better. But, as the trends happening here and nationwide show, there’s no room for complacency. For those who may be concerned about their STD status, it’s easy to get tested and find out for sure. Most people who do have STDs don’t know it, which increases the risk of them continuing the spread of the disease, which is why testing is a crucial part of bringing STD rates down in Rhode Island and across the U.S.

Additional References

Note: Some states have published more recent data for chlamydia, gonorrhea, and primary and secondary syphilis. For states in which that’s the case, we have substituted the individual state data for 2018 and used that in our rankings, while other states’ rankings are based on 2017 numbers. In some cases, we assume that when the full national dataset is published by the CDC, states’ positions relative to other states will change some, though those changes are unlikely to be dramatic, since the CDC data comes from the states.
