This pamphlet from Fox Pro Media's In the Know series profiles the most common STD, which afflicts some 3 million Americans a year.
It explains that most people infected with chalmydia have no symptoms, and thus do not seek treatment or take measures to prevent its further spread.
It warns that untreated chalmydia can cause subsequent inflammatory conditions in the genitals of both sexes, capable of rendering victims sterile.
Readers learn that chlamydia is curable, but must be caught early to prevent irreversible damage, so people who are sexually active should be tested periodically.
Abstaining from sex, resrtricting sex to one uninfected partner and using a condom for all forms of sex are recommended as means of preventing chlamydia's spread.
Readers wishing to know more about the subject are referred to www.intheknowzone.com, Fox Pro Media's free STD information Web site, and to the National STD Hotline.
