Chorioamnionitis

Overview
Chorioamnionitis is an inflammatory condition of pregnancy affecting the uterus. According to a 2000 report by Dr Yvonne W. Wu, a pediatric neurologist at the University of California in San Francisco, chorioamnionitis is one of the most common causes of brain injuries in newborns.

The amniotic sac consists of two membranes:
 * The outer membrane, the chorion, contains the amnion and is part of the placenta.
 * The inner membrane, the amnion, contains the amniotic fluid and the fetus.

Chorioamnionitis is an inflammation of the chorion and amnion. It is usually caused by a bacterial infection.
