In fact, the CDC estimates there are over 110 million sexually transmitted infections among men and women in the U.S., with 20 million new cases each year. HPV is the most common STI (79 million cases), followed by genital herpes (24 million), trichomoniasis (3.7 million) and chlamydia (1.6 million).
Human Papillomavirus (HPV) Infection
HPV is the most common STI in the United States, but most people with the infection have no symptoms. HPV can cause some health effects that are preventable with vaccines.
HPV. While HIV may be the most well-known and feared STD, Human Papillomavirus is the most common. According to the CDC, approximately 79 million Americans are currently infected and nearly all sexually active men and women will contract HPV at some point in their lives.
All incurable STDs are viral. The most dangerous viral STD is human immunodeficiency virus (HIV), which leads to AIDS. Other incurable viral STDs include human papilloma virus (HPV), hepatitis B and genital herpes.
About 16 per cent of Australians report having an STI at some point in their lifetime — that's roughly 4 million people. With the exceptions of hepatitis and HIV, Australia's most common STIs are on the rise.
The report titled HIV, viral hepatitis and sexually transmissible infections in Australia: Annual surveillance report shows that in 2021 there were 86,916 diagnoses of chlamydia, 26,577 of gonorrhoea and 5,570 of infectious syphilis in Australia.
Chlamydia is very common: it's the most frequently reported infectious disease in Australia, and nearly 97,000 men and women are diagnosed with it each year. If you're sexually active and under 30 years of age, you are at the highest risk of contracting chlamydia.
Herpes is easy to catch. All it takes is skin-to-skin contact, including areas that a condom doesn't cover. You're most contagious when you have blisters, but you don't need them to pass the virus along. Because herpes is a virus, you can't cure it.
Trich is the most common curable STD. A healthcare provider can treat the infection with medication (pills) taken by mouth. This treatment is also safe for pregnant people. If you receive and complete treatment for trich, you can still get it again.
Trichomoniasis (or “trich”) is the most common of the curable STIs. The organism Trichomonas vaginalis is a parasite which lives in the lower genital tract and is generally transmitted through sexual intercourse.
Sexually transmitted infections (STIs) are very common, and over half of people in the U.S. will have an STI in their lifetime. In fact, the CDC estimates there are over 110 million sexually transmitted infections among men and women in the U.S., with 20 million new cases each year.
Symptoms usually appear after 1 to 3 weeks but can start much later. Symptoms include: discharge from the vagina or penis. pain when peeing.
Women are also biologically more vulnerable to STDs than are men. Women are more susceptible to STDs during sexual intercourse because the vaginal surface is larger and more vulnerable to sexual secretions than the primarily skin-covered penis.

More testing means more diagnosis
Advances in technology have created more accurate tests, which have helped to identify more infection. The number of tests conducted has increased over time as well. More people testing more often and more accurately means, by default, more infection will be found.
Researchers estimate that as many as one in four sexually active adolescent females has an STD. Why is this percentage so high, and what can we do to reduce it?
In Australia, men who have sex with men (MSM) are a population particularly at risk of sexually transmitted infections (STIs) such as gonorrhoea, chlamydia, syphilis and HIV. Since 2004, rates of unprotected anal intercourse with casual male partners have increased among MSM.
Incurable STDs. Currently, there are 4 sexually transmitted infections (STIs or STDs) that are not curable: herpes (HSV), hepatitis B (HBV), human immunodeficiency virus (HIV), and human papillomavirus (HPV).
Gonorrhea has progressively developed resistance to the antibiotic drugs prescribed to treat it. Following the spread of gonococcal fluoroquinolone resistance, the cephalosporin antibiotics have been the foundation of recommended treatment for gonorrhea.
If you receive a positive test result for an STI, such as chlamydia or syphilis, and you're fairly certain you got it from your partner, then it's important to talk with them about it as soon as possible. Don't wait or put it off — the longer you wait, the harder it may be to tell them about it later.
