Syphilis, once nearly eliminated in the United States, continues to resurge, reaching the highest rate of new infections recorded since 1950, the Centers for Disease Control and Prevention said on Tuesday.

According to a new C.D.C. report, more than 207,000 cases were diagnosed in 2022, the last year for which data are available. That represents an 80 percent increase since 2018, and 17 percent over the previous year’s tally.

Three board-certified dermatologists are available to share their expertise on the medical condition.
