Screening

Bacterial vaginosis

Bacterial vaginosis is known to increase the risk of pregnancy complications (e.g., preterm premature rupture of membranes, preterm birth) but the evidence does currently not support routine screening for bacterial vaginosis in asymptomatic pregnant women.[4][36]​​[37]​ There is insufficient evidence to assess the trade-off between benefits and harms of screening asymptomatic pregnant women at high risk of preterm delivery.

Although bacterial vaginosis occurs more commonly in women with female sexual partners, routine screening for bacterial vaginosis is currently not recommended for this population.[38][39]

Trichomonas

Screening for Trichomonas vaginalis should be considered in women at high risk for infection (i.e., women who have new or multiple partners, have a history of STIs, exchange sex for payment, or use injection drugs).[4]

Although T vaginalis infection is known to increase the risk of pregnancy complications (e.g., preterm premature rupture of membranes, preterm birth), the evidence does not currently support routine screening in asymptomatic pregnant women at low risk of infection.[4] Screening is recommended at first prenatal visit for pregnant women with HIV infection, because T vaginalis infection increases risk of vertical transmission of HIV.[4]
