Congenital Syphilis
Congenital syphilis (CS) is an infection transmitted from pregnant person to child during pregnancy and/or delivery caused by the bacterium
Treponema pallidum. CS can cause severe illness in infants including premature birth, low birth weight, birth defects, blindness, and hearing loss. It can also lead to stillbirth and infant death. Tests and treatment for pregnant people are readily available.
Over the last several years, California has experienced a steep increase in syphilis among females and CS. From 2012 to 2021, female early syphilis cases increased over 1,113 percent and CS cases increased 1,500 percent, from 33 cases in 2012 to 528 cases in 2021. This is the highest number of reported CS cases since 1992 when 522 cases were reported. According to the U.S. CDC, California had the 11th highest congenital syphilis rate of all states in 2021. Thirty-seven (60.7 percent) of Californiaās 61 local health jurisdictions reported at least one case of congenital syphilis in 2021. Most pregnant females who gave birth to infants with CS received prenatal care late in pregnancy or not at all.
