Syphilis cases in U.S. newborns again are on the rise. It has health officials calling for new measures to stop the increase, including encouraging millions of sexually active women of childbearing age and their partners to get tested. The Centers for Disease Control and Prevention says more than 3,700 babies were born with congenital syphilis in 2022. That's 10 times more than a decade ago and a 32% increase from 2021. CDC officials say there needs to be expanded testing. The agency also suggests starting syphilis treatment as soon as a pregnant woman tests positive.
