About half of all cases of urethritis that are not gonorrhea are chlamydia , which is caused by an infection with Chlamydia trachomatis. Groups with the highest rates of STDs are often the same groups for whom access to or use of health services is most limited. This fact sheet is based on information from the following sources: From CDC:. Finally, pregnant women and their infants are particularly vulnerable to complications of STD during pregnancy or parturition. At least one-quarter of women with acute pelvic inflammatory disease will experience serious long-term sequelae, the most common and important of which are ectopic pregnancy the development of a fetus outside the uterus and tubal-factor infertility.

The virus affects the areas where it entered the body. For example, women infected with certain types of human papillomavirus are at risk for cancers of the cervix a relatively common malignancy , as well as cancers of the vagina, vulva, and anus; whereas heterosexual men infected with these human papillomavirus types are at risk only for cancers of the penis a relatively uncommon malignancy. Apart from being serious diseases in their own right, sexually transmitted infections increase the risk of contracting or transmitting HIV infection. STDs are severe public health problems because of their potentially serious complications as well as their potential to increase the efficiency of HIV transmission. Fam Plann Perspect ;, Washington: Institute of Medicine; These types of reminders are now used in addition to phone calls and letters.
