Sexually Transmitted Diseases (STDs)
Sexually Transmitted Diseases (STDs)
More than 25 diseases are spread primarily through sexual activity. The latest estimates indicate that there are 15 million new sexually transmitted disease cases in the United States each year. Approximately one-fourth of these new infections are in teenagers. Nearly two-thirds of all STD cases occur in people younger than 25 years.
While some sexually transmitted diseases, such as syphilis, have been brought to all-time lows, others, like genital herpes, gonorrhea, and chlamydia, continue to resurge and spread through the population.
Not including HIV, the most common sexually transmitted diseases in the U.S. are chlamydia, gonorrhea, syphilis, genital herpes, human papillomavirus, hepatitis B, and trichomoniasis.
