The number of syphilis cases in the U.S. are on the rise. According to a new report from the Centers for Disease Control and Prevention, cases increased by nearly 80% to more than 207,000 between 2018 and 2022.

Rates increased among all age groups, including newborns, and in all regions of the country. In 2022, 3,755 cases of babies born with syphilis in the U.S. were reported, which reflects an alarming 937% increase in the past decade, the CDC said.
