Cervicitis also known as cervical inflammation is the inflammation of the cervix(the lower, narrow end of the uterus that opens into the vagina). It's a common infection of the lower genital tract. The closed cervix acts as a barrier to keep bacteria and viruses that come in contact with the vagina from entering the uterus. However, when bacteria and viruses infect the cervix, they cause inflammation and may increase the risk that the infection can travel to the uterus.
