Streptococcus B positive, if the infection is effectively controlled, it is possible to have a normal labor in this case. However, if it is still positive when labor is imminent, normal delivery is not recommended in this case. Usually women need to go to the hospital to check if they have a group B streptococcus infection in the late stages of pregnancy. If the test is positive for group B streptococcus, it means that there is an infection of group B streptococcus, which may affect labor. When a group B streptococcus infection is found in late pregnancy, timely use of antibiotics to treat the infection is relatively effective, and the infection is usually able to be controlled with three consecutive days of medication. If the infection is under control, it is possible to have a normal labor, and this has no effect. If the symptoms of labor have already appeared in late pregnancy, and then found to have B streptococcus infection, this situation is not recommended to deliver vaginally, otherwise it may lead to infection of the newborn. If vaginal delivery is unavoidable, it is recommended that both the mother and the newborn be treated with anti-infection therapy after delivery.
