Preliminary data recently released by the Centers for Disease Control and Prevention shows that cases of syphilis, gonorrhea, and chlamydia all went up last year.

There were at least 2.5 million reported cases of chlamydia, gonorrhea, and syphilis in the U.S.

Instances of chlamydia in 2021 (around 1.63 million cases) were slightly down from their high in 2019 but were higher than 2020’s total, and cases of gonorrhea and syphilis have continued to climb year after year.

There were 696,764 reported cases of gonorrhea in 2021, along with 171,074 cases of syphilis.

Rates and cases of congenital syphilis passed down from mother to child in the womb have also increased, with 2,677 cases in 2021.

And without effective drugs, gonorrhea cases will more often cause serious complications like infertility or blindness in newborns who contract the infection while in the womb.
