What are the most common STDs?


Chlamydia, Herpes, Gonorrhea, HPV, and Trichomoniasis are the most common STDs ranked by the number of people infected. Chlamydia is the most commonly reported disease in the US.

In 2017, almost two-thirds of all reported chlamydia cases were among persons aged 15–24 years. Second most common among notifiable diseases is gonorrhea. Rates of reported gonorrhea increased by 75.2% since the historic low in 2009 and increased by 18.6% since 2016.
Trichomoniasis is the most common curable STD, and is more common in women than men. It infects 2.3 million (3.1%) women ages 14-49 in the US.

It is believed 1 in 8 people have genital herpes, but most people do not have any symptoms. 

Researchers estimate that at least 80% of sexually active people will have an HPV infection at some point in their lifetime. Most of the strains of the virus are harmless and your body will clear them its own. The HPV vaccine protects against the strains most likely to cause cancer.
