Syphilis Cases Are Up 80% Since 2018
12:09 minutes

Syphilis is rearing its ugly head again in the United States. A new report on sexually transmitted infections (STIs) from the Centers for Disease Control and Prevention shows a shocking statistic: Cases of syphilis are up by nearly 80% among adults since 2018. Congenital syphilis cases, which occur when an infection is passed from parent to child during pregnancy, are up by more than 180%.
Strangely, cases of other STIs have stayed about the same or decreased in the same timeframe. Rachel Feltman, host of “The Weirdest Thing I Learned This Week,” joins Ira to talk about this and other science stories from the week, including the first cases of transmitted Alzheimer’s disease, and why closing the toilet seat doesn’t keep aerosolized viruses from contaminating other bathroom surfaces.
Rachel Feltman is author of Been There, Done That: A Rousing History of Sex, and is the host of “The Weirdest Thing I Learned This Week.”

Kathleen Davis is a producer at Science Friday, which means she spends the week brainstorming, researching, and writing, typically in that order. She’s a big fan of stories related to strange animal facts and dystopian technology.
Ira Flatow is the host and executive producer of Science Friday. His green thumb has revived many an office plant at death’s door.
