The United States has recorded four straight years of increasing rates of several common sexually transmitted diseases, such as chlamydia, syphilis and gonorrhea. In Hawaii, the situation is a little more complex. While some rates are climbing and most are higher than they were a half-decade ago, the past couple of years have seen declines here in Hawaii.

Which STDs are most prevalent here in Hawaii, how does the state stack up with others, what has happened to STD rates over the past several years, and which locales in Hawaii are the biggest hotbeds of sexually transmitted diseases and infections? To answer all those questions, we’ll check out data from the federal Centers for Disease Control and Prevention.

Chlamydia Rates in Hawaii

Hawaii’s population-adjusted chlamydia infection rate ranks the state No. 32 among the 50 states, and Hawaii’s rate is just under 10% less than the overall U.S. rate. Still, Hawaii’s rate is more than twice as high as that of West Virginia, the state with the lowest rate.

Hawaii has seen two consecutive years of decline in the chlamydia rate, but the rate has risen about 5% since 2012.

Gonorrhea Rates in Hawaii

The population-adjusted rate of gonorrhea in Hawaii is low enough to put the state at No. 42 overall, and Hawaii is one of only nine states with rates below 100 per 100,000 people. Hawaii’s rate is more than three times lower than that of Mississippi, the national leader, but is nearly three times higher than that of Vermont, which has the lowest rate in the country.

Between 2016 and 2017, Hawaii’s gonorrhea rate fell, but taking a longer view shows that the rate has climbed more than 60% since 2012.

Half of the 10 states with the lowest gonorrhea rates are in the West, and Hawaii ranks in the bottom half of the region.

Syphilis Rates in Hawaii

The rate at which primary and secondary syphilis infections occur in Hawaii is high enough to place the state in the top half nationally, though the state’s rate is still far behind Nevada, which leads the nation.

Hawaii’s syphilis rate has varied somewhat over the past three years, but it’s virtually exploded since 2012, rising more than 288% since then.

HIV & Other STD Rates in Hawaii


More than 80 people were newly diagnosed with HIV in Hawaii in 2017, which represents a 4% increase from the previous year. Among the states, Hawaii ranks 33rd for its population-adjusted HIV rate. See best HIV test options.

Hepatitis B & C

The prevalence of acute hepatitis B has dropped in recent years here in Hawaii to a statistically insignificant rate. Acute hep B occurs in the U.S. at a rate of 1 per 100,000, and the most recent year in which Hawaii had a detectable rate, the viral infection occurred at the same rate as the national rate. Hawaii has not reported its rate of acute hep C for several years. See best hepatitis test options.


Human papillomavirus (HPV), while the most common STD in the world, is difficult to pinpoint. This is partially because it’s so very common, but it’s also because the vast majority of people who have it don’t have any signs of the disease. But untreated HPV can be very dangerous, or even deadly. That’s why examining a state’s rate of HPV-related cancers can be a window into understanding the virus. Nationally, the median rate for these cancers is 11.7 per 100,000, but Hawaii’s rate of 9.4 per 100,000 is the fourth-lowest in the nation. See best HPV test options.

STDs in Hawaii Cities & Counties

While Hawaii is generally not among the leaders when it comes to how common sexually transmitted diseases and infections are, the rates vary depending on the geography being examined, and the city of Honolulu accounts for the majority of cases.


More than 3 in 4 chlamydia cases in Hawaii were diagnosed in people living in Honolulu.

Maui 383.9

Honolulu accounted for nearly 9 in 10 cases of gonorrhea.

Hawaii has managed to buck national trends in recent years when it comes to the prevalence and growth of sexually transmitted diseases and infections. But when comparing rates to those recorded 5-6 years ago, most diseases have grown in frequency in Hawaii, which means that it’s likely that many people who are infected are unaware. Through getting yourself tested and being vigilant about practicing safer sex, everyone has the power to keep making progress against STDs in Hawaii.

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.
