Chlamydia is a sexually transmitted infection (STI) caused by the Chlamydia trachomatis bacteria and transmitted by oral, anal or vaginal sex. It is one of the most commonly transmitted STIs, with 1,244,180 cases reported to the Center for Disease Control in 2009. The reason it is so prevalent is Chlamydia's lack of obvious symptoms. Most men and women don't have symptoms. When symptoms are present, they are usually different in men and women.
BabyCenter.Com states that approximately 3 million new cases of chlamydia occur each year in the United States alone. Although this sexually-transmitted infection can affect both men and women, it has potentially serious side effects for pregnant women in particular. Knowing the signs of chlamydia during pregnancy will help you identify and obtain treatment for this infection more quickly.
