General Sexually Transmitted Diseases Statistics
About one in five people in the US acquire an STI every day. According to the latest data, the reported sexually transmitted disease cases in the country have reached a historic high.
1. 20% of the US population has an STI on any given day.
The percentage of people with STDs is relatively high. According to CDC data, one in five people in the US has a sexually transmitted infection on any given day every year. Chlamydia, genital herpes, trichomoniasis, and HPV account for 98% of newly acquired STDs. Additionally, estimates are that newly acquired STIs cost the healthcare system $16 billion.
2. Statistics on STD reveal there are over 2.5 million chlamydia, gonorrhea, and syphilis cases reported in one year.
The reported STDs in the US have reached an all-time high for a sixth consecutive year. More specifically, there are 1.8 million chlamydia, 616,392 gonorrhea, and 129,813 syphilis cases. Additionally, there are 1,870 congenital syphilis cases, which has seen an increase of 279% since 2015.
3. The gonorrhea rate in the US is 124 per 100,000 people.
(World Population Review)
As gonorrhea statistics show, the US has the highest gonorrhea rate at 124 per 100,000 people in the developed world. Additionally, it has the third-highest rate for chlamydia of 479 per 100,000 people. These STD rates are rising due to many reasons, including decreased condom use among vulnerable groups, decreased care and screening, and reduced patient follow-up due to budget cuts of the state and local programs.
4. HPV is the most common STD type in the US, with more than 20 million confirmed cases.
(World Population Review)
STD statistics worldwide indicate that human papillomavirus (HPV) is the most widespread STD type globally. According to estimations, there are more than 600 million cases. The disease is also the most common STD type in the US, with 20 million cases.
5. An estimated 1.2 million people in the US have HIV.
As per sexually transmitted diseases stats, around 1.2 million people in the US live with HIV. However, about 13% of them aren’t aware of it and don’t know they need testing. In addition, 34,800 newly diagnosed cases appeared in the US. It should be noted that HIV has the highest direct medical costs of nearly $14 billion — almost six times more than other STDs combined.
STDs Prevalence by Age, Gender, and Ethnicity
Syphilis is most widespread among young men, particularly gay and bisexual men. However, females are more prone to get gonorrhea than men.
6. Sexually transmitted diseases rates are 5–8 times higher for African Americans or Black people.
According to the CDC report, African American or Black people have 5–8 times higher rates of STD than non-Hispanic White people. Additionally, the rates are 3–5 times higher for Native Alaskans, American Indians, and Native Hawaiians, and 1–2 times higher for Hispanic or Latino people.
7. Among men, the US STD rates of reported gonorrhea infections increased by 60.6% in four years.
CDC reports that the prevalence of gonorrhea cases among men increased by 60.6% between 2015 and 2019 and 5.9% between 2018 and 2019 only. On the other hand, the rates have increased by 43.6% and 5.1% in the respective periods among women. The expanded rate is likely due to increased case ascertainment and transmission.
8. The STD percentage among gay and bisexual men with syphilis is nearly 50%.
The primary and secondary syphilis rates among men increased by 8% to 20 cases per 100,000 men. Men account for 83% of all instances of primary and secondary syphilis, and the rates for gay and bisexual men stand at 47% of all syphilis cases reported.
9. Females are three times more likely to get gonorrhea than men.
STD transmission rates for gonorrhea after just one sexual encounter with an infected partner are 60–90% for women. In comparison, the male’s risk of being infected with the disease by a female is only 20%. Such a significant difference might be related to the larger exposed genital surface area and greater exposure to trauma and tissue damage in females.
10. With 57.6 cases per 100,000 people, syphilis is most common in 25–29-year-old men.
STD statistics by age show that syphilis is most prevalent among men in the 25–29 age group, with a rate of 57.6 per 100,000 population. Additionally, the rate of syphilis cases among men in the 30–34 age group is 51.2 per 100,000, whereas there are 45.2 cases per 100,000 people among men aged 20–24en.

According to the latest stats, 77% of female teenagers have received at least one HPV vaccination dose, compared to 72% of males.
Global Statistics on STD
Worldwide, there’s a staggering number of STDs acquired every day. One in every 25 people gets infected with chlamydia, trichomoniasis, gonorrhea, and syphilis daily.
20. Globally, there are one million new cases of STD every day.
More than one million cases of STDs are reported every day. The four main infections reported are chlamydia, trichomoniasis, gonorrhea, and syphilis. On average, one in every 25 people globally is infected with one of these STIs. Furthermore, there are over 376 million new cases annually, including people with multiple STIs and those that become re-infected with one or more STIs within a year.
21. There are over 129 million new cases of chlamydia every year in the world.
The STD rates for chlamydia show there are over 129 million new cases worldwide. Moreover, nearly 500 million people live with genital herpes infection, and an estimated 300 million women have an HPV infection.

(World Population Review)
Following the US and Australia, Singapore is ranked third for the highest rates of STD in general. Additionally, its global rate for syphilis ranks the highest, with 30.39 cases per 100,000 people. Such a high rate might be because the government didn’t previously educate the population on STD prevention.
24. Statistics on STDs reveal that the UK recorded 70,936 cases of gonorrhea pre-pandemic.
Before the pandemic, gonorrhea cases have been at a record-high level in the UK in the past 100 years. The country counts 70,936 reported cases. The most significant proportional increase was noted in the 20–24 age group, with rates rising by 28% to 17,443 confirmed cases.

Staying educated, using protection every time you engage in sexual activity, and getting tested regularly are crucial to ensuring you’re staying safe and preventing further transmission.
People Also Ask
What percentage of the population has an STD?
About 20% of the US population is infected with sexually transmitted diseases on any given day over the course of one year. That’s one in five people. The most widespread STIs are chlamydia, genital herpes, trichomoniasis, and HPV. These four STIs account for 98% of newly acquired infections. STIs burden the healthcare system, costing almost $16 billion a year.
What is the number one reported STD?
Chlamydia is the top reported STD in the US. According to CDC, there are 1,808,703 confirmed cases. The rate of reported cases is 553 per 100,000 people. Moreover, there are 616,392 reported gonorrhea cases, or 188 per 100,000 rates, whereas the syphilis rate amounts to 40 per 100,000 people or a total of 129,813 cases.
Why are STD rates rising?
There are many reasons why the number of STD cases is on the rise. One of them is the limited resources which make it challenging to identify and treat STDs. Additionally, the rising rates of drug use and poverty also influence the high sexually transmitted diseases rates. On top of that, fewer people are using condoms, and the STD prevention programs at the state and local levels have experienced budget cuts.
What are the odds of getting an STD?
Unfortunately, getting an STD is quite likely, especially for people who have sex without condoms. Even if you have only one sexual partner, you could be infected if that person had the disease. Additionally, you shouldn’t overlook that STDs are also transmitted through oral sex. The chances of getting infected from oral sex depend on the type and severity of the infection, its prevalence in the population, and the use of protection.
How many STDs does the average person get?
Some data suggests that one in two Americans will get at least one sexually transmitted infection in a lifetime, and the majority of them will contract it by age 25. That said, it’s possible to have two or more STDs at the same time, which would usually happen if you’ve had several sexual partners since your last STD test or you engage in sexual activity with someone who already has two STDs.
Are all STDs curable?
More than 30 bacteria, parasites, and viruses can be transmitted through sexual contact. Eight of them are linked to the most prevalent STDs. Four of these — syphilis, chlamydia, gonorrhea, and trichomoniasis — are curable. The other four — herpes simplex virus, HIV, hepatitis B, and HPV — are incurable. That said, if you leave curable STDs untreated, you will put yourself at risk for serious health outcomes, as illustrated in the STD statistics above.
