There has been a significant increase in syphilis cases among expectant mothers since the pandemic. The rise in cases is being reported nationally, with some areas such as California experiencing a notable spike, and has led to an increase in congenital syphilis cases, resulting in infant deaths. The trend is part of a broader global rise in syphilis cases, with public health officials warning of an "alarming" resurgence and urging those who are sexually active to get tested.
