Bacterial vaginosis.
Bacterial vaginosis is the most common cause of vaginal infectious morbidity, including vaginal discharge. The condition is easily diagnosed and treated. If undiagnosed or left untreated, the condition is associated with serious adverse sequelae in both obstetrics and gynaecology. If bacterial vaginosis is detected in early pregnancy, the woman has a five-fold increased risk of late miscarriage or preterm delivery compared with women without the condition. Further research is necessary to establish whether adverse sequelae such as premature labour, preterm prelabour rupture of the membranes, late miscarriage or postpartum endometritis can be reduced by treating the condition in early pregnancy.
