Partner notification and treatment for sexually transmitted infections among pregnant women in Cape Town, South Africa.

Curable sexually transmitted infections (STIs) including Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) are associated with adverse pregnancy outcomes. Partner notification is an important component of STI control as it has been shown to prevent re-infection and reduce infectious burden. Between October 2017 and February 2019, we conducted a cohort study of women attending antenatal care in Cape Town, South Africa. Self-collected vulvovaginal swabs were tested for CT, NG, and TV using Xpert® assays at first antenatal visit, during the third trimester, and postpartum. At the visit following a positive diagnosis, women were asked if they notified their partner and if their partner was treated. Among 242 participants, 97% reported being willing to notify partners if they tested positive and 78% thought their partner would be willing to treat the STI. Of the 73 women who were diagnosed with one or more STIs and reported having a sex partner, 93% reported notifying their partner and 63% reported their partner was treated. Younger maternal age was associated with partner notification and treatment (OR = 3.82; 95%CI = 1.34-10.90). Acceptability of partner notification was high in pregnant women, but partner treatment was low. Future interventions to improve partner notification and treatment are needed.
