Chorioamnionitis is a condition characterized by inflammation of the fetal membranes (chorion and amnion) and the amniotic fluid surrounding the fetus. It is typically caused by a bacterial infection ascending from the vagina and cervix into the uterus during pregnancy. Chorioamnionitis is associated with various adverse outcomes for both the mother and the baby, including preterm birth, neonatal sepsis, and complications during childbirth. Research in this area focuses on understanding the mechanisms of infection, developing effective diagnostic methods, and exploring potential treatments to improve outcomes for pregnant women and their babies.
