CDC Warns of Alarming Increase in Syphilis Cases, Urges Regular STI Testing

The US Centers for Disease Control and Prevention (CDC) has reported a 7% increase in the number of sexually transmitted infections (STIs) in 2021, with syphilis rates surging by an alarming 32%.

The CDC expressed concern that the pandemic had disrupted screening for STIs, particularly for chlamydia, which is often asymptomatic. Chlamydia accounted for more than half of the reported cases, with rates increasing about 4% in 2021.

The most alarming increase was in cases of congenital syphilis, which happens when a mother with syphilis passes the infection on to her baby during pregnancy. Congenital syphilis cases rose by 32%, causing 220 stillbirths and infant deaths in 2021.

Dr. Leandro Mena, director of the CDC’s Division of STD Prevention, said: “The US STI epidemic shows no signs of slowing. The most important thing to remember is that congenital syphilis is 100% preventable.”

The CDC recommends that all pregnant women be tested for syphilis at their first prenatal visit and that all sexually active people get tested for STIs at least once a year. They also recommend that people who are at high risk of STIs be tested more frequently.
