How long does strep last after antibiotics

Cochrane

Women, men and children of all ages can wear Group BStreptococci-Bacteria (GBS) without showing any symptoms. Group B streptococci occur primarily in the digestive tract, vagina, and urethra. This is the case in both developed and developing countries. About 1 in 2000 newborns will have GBS infections. Most of these can be recognized by respiratory diseases, general sepsis ("blood poisoning") or meningitis in the first week of life. The child is infected during the birth from the mother. If the mother is given an antibiotic directly into the vein during childbirth, the number of bacteria decreases rapidly. This could be useful, but all pregnant women would have to undergo routine screening. Guidelines for GBS screening during pregnancy and antibiotic treatment are already in place in many countries. Affected unborn babies are particularly at risk when it comes to a premature birth with a low birth weight, a long birth time, premature rupture of the bladder (more than 12 hours before birth), serious changes in the child's heart rate in the opening phase or gestational diabetes. Of all women giving birth with GBS, very few of the children born are infected. Antibiotics can have negative effects such as severe allergic reactions in the mother, an increase in treatment-resistant germs and the risk of infection in the newborn with resistant bacteria, as well as fungal infections in mother and child after birth.

The administration of antibiotics has not yet been supported by sufficient evidence. The review included four studies involving a total of 852 women with GBS. Three studies, all older than 20 years, compared the administration of ampicillin or penicillin with childbirth accompaniment without administration of medication. The result showed no significant differences in deaths in newborns, although the risk of early GBS infection in the newborn could be reduced with antibiotics. In a study with 352 GBS-infected women, no difference in the effect could be found between the antibiotics ampicillin and penicillin. Even if an effective vaccine were developed, not all birth-related GBS infections could be prevented.
