Background Paragraph: Chlamydia may cause a burning feeling during urination. It may also cause a discharge (leaking of fluids) from the vagina or penis. But in many cases it causes no symptoms. As a result, people do not know they are infected, so they don’t go to the doctor for help. If chlamydia goes untreated, it may cause more serious problems in females. It may cause infections of the uterus, fallopian tubes, or ovaries. These infections may leave a woman unable to have children. 
Story: At a doctor's office, two people come in to get STD tests. John comes in and reports the only symptom he has is a rash on his thighs. Patty says she has seen something leaking out of her vagina, and she's not sure what it is. The doctor takes a urine sample from each and will give them the results in a day or two.
