During 2018\u20132019, 258 (32%) of 809 pregnant women with syphilis delivered babies with CS. Comparing CS prevention rates, it was determined that 65% of the increase in CS was due to the increases in maternal syphilis infections. The proportion of maternal cases staged as primary or secondary increased over time (7%\u201313%) (p&lt;0.01) and reports of drug use became slightly more common (6%\u201310%) (p=0.02). During 2018\u20132019, women delivering CS infants were more likely to be reinfected during the same pregnancy (27 (10%) vs 5 (6%) p=0.23) and more had negative third trimester screening tests (43 (17%) vs 7 (8% p=0.07)). The percentage of infants with CS who had \u22651\u2009sign or symptom increased from 35% to 40%, and the combined total of stillbirths and infant deaths increased from 5 to 26.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Recently, more pregnant women are being infected with syphilis and a higher per cent are not being treated to prevent CS.
