2016 STD Surveillance Report

September 26, 2017 – STDs at record high, threatening the health of millions of Americans

New CDC data for three nationally reported STDs – chlamydia, gonorrhea, and syphilis—reveal more than 2 million cases were diagnosed in 2016. CDC estimates that closer to 20 million infections occur annually.

The majority of these diagnoses (1.6 million) were cases of chlamydia. There were also 470,000 gonorrhea cases and almost 28,000 cases of primary and secondary syphilis – the most infectious stages of the disease. While young people, particularly young women aged 15-24, continue to bear the greatest burden of STDs, surges in syphilis and gonorrhea are increasingly affecting new populations.

The Value of Chlamydia Screening

This animation shows the benefit and importance of chlamydia screening. Identifying asymptomatic infections can prevent life-long health complications. Once identified, chlamydia can be easily cured with a single dose treatment. If not identified, chlamydia can result in infertility, pregnancy complications, and increased risk of infecting others. CDC recommends annual chlamydia screening for women 25 and under, as well as for older women at high risk.
