Congenital Syphilis in Texas Section 4 - An Overview of Congenital Syphilis and Syphilis in Women of Childbearing Age in Texas


In 2018, there were 367 CS cases reported in Texas, a 124 percent increase from 2017 (Figure 2). This is a rate of 91.0 CS cases per 100,000 live births. Concurrently, there was an increase in reporting of all stages of syphilis in women of childbearing age. In 2018, there were 1,139 cases of early syphilis (primary, secondary, and early non-primary non-secondary) reported among women of childbearing age in Texas, representing a 42 percent increase from 2017 (Figure 2). There were 2,402 total syphilis cases (primary, secondary, early non-primary non-secondary, and unknown or late duration) among women of childbearing age, which is a 20 percent increase from 2017 (Figure 3).

Congenital Syphilis and Syphilis in Women of Childbearing Age by Geographic Area


The majority of CS and syphilis cases in women of childbearing age occurred around Texas metropolitan areas. In 2018, the top five Texas jurisdictions reporting the highest number of CS cases accounted for 79 percent of all CS cases (Figure 4). Three jurisdictions accounted for half the cases of women of childbearing age diagnosed with syphilis (Figure 5).

STD surveillance sites with higher proportions of women of childbearing age diagnosed with syphilis also had a higher proportion of CS cases (Figure 8).
