Chorioamnionitis affects which structures according to the provided material?

• A. Fluid, placenta, fetus, membranes, or decidua
• B. Only the myometrium
• C. Only the amniotic sac
• D. Only the umbilical cord

Answer: (A)

Chorioamnionitis is an intrauterine infection that involves multiple components of the fetal–maternal interface. The infection starts in the fetal membranes (chorion and amnion) and commonly involves the amniotic fluid; it can extend to the placenta (placentitis) and the maternal decidua (deciduitis). The fetus itself can be affected by the infection, leading to fetal inflammatory responses or sepsis if untreated. Because of this spread across several structures, the most accurate description includes fluid, placenta, fetus, membranes, and decidua. Limiting involvement to just one structure—like the myometrium, the amniotic sac, or the umbilical cord—does not reflect how chorioamnionitis typically behaves.
