In 2016, a record high of over 2 million cases of chlamydia, gonorrhea, and syphilis were reported in the United States, as per the Centers for Disease Control and Prevention (CDC)’s annual Sexually Transmitted Disease Surveillance Report. Specifically, there were 1.6 million cases of chlamydia, 470,000 of gonorrhea, and nearly 28,000 cases of primary and secondary syphilis. 

Almost half of the diagnosed chlamydia infections occurred in young women. Increases in syphilis were seen across different patient populations including gay, bisexual, and other men who have sex with men (MSM) (these groups made up the majority of cases), women (36% increase) and newborns (congenital syphilis; 28%). A substantial increase in gonorrhea infections was also noted among men, particularly MSM (22%), although increases in women were seen as well.

“Increases in STDs are a clear warning of a growing threat,” said Dr. Jonathan Mermin, director of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention. “STDs are a persistent enemy, growing in number, and outpacing our ability to respond.” Given this new data, the CDC recommends that clinicians make STD screening and treatment a regular part of medical care (eg, prenatal care, HIV prevention) especially for pregnant women and MSM.
