The latest Centers for Disease Control and Prevention (CDC) Sexually Transmitted Disease (STD) Surveillance Report shows that STD rates increased for the fourth consecutive year in 2017, and there has been a steep, sustained increase in the incidence of all three reportable STDs. While these STDs are treatable, if untreated, they can cause serious health consequences such as pelvic inflammatory disease, infertility, and stillbirth.
Firstly, gonorrhea diagnoses increased by almost 70% percent overall and nearly doubled among men. Increases in diagnoses among women, and the speed with which they are increasing, are also concerning, with cases going up for the third year in a row.
Primary and secondary syphilis diagnoses increased 76%. Congenital syphilis (transmitted from the pregnant person to the fetus) cases rose sharply with 918 cases in 2017, a number that has more than doubled since 2013. This included 64 reported stillbirths as a result of congenital syphilis (up from 41 in 2016).
Lastly, chlamydia remained the most common condition reported to CDC. More than 1.7 million cases were diagnosed in 2017, with 45% of cases among 15- to 24-year-old females. The preliminary data for 2018 sadly shows these trends continuing and a new CDC analysis suggests that gay and bisexual men are at a higher risk for extragenital STDs (e.g. chlamydia or gonorrhea in the throat or rectum), which increases treatment difficulty, drug resistance, and the risk of HIV infection.
