About 3% to 6% in the US have chlamydia at any given time. Rates of infection in the general population appear to be the same among males and females, although female reported cases are higher (likely due to programs encouraging screening in young women). In females, 50% will have chlamydia by the age of 30. The rates are probably similar for males. See related link for references.

Most people with chlamydia (80-90% of females and half of males) have no symptoms of chlamydia, or symptoms so mild that they are almost unnoticed. For this reason, symptoms may be perceived as having gradual or sudden onset, depending on the type of symptom experienced. Painful urination, for instance, may appear suddenly. Pelvic pain is likely to have a more subtle and gradual onset.
Both males and females can have chlamydia. The most common age group to be infected is 15 to 25 years old.
While reported cases are higher in females than in males, studies in the general population suggest that males and females are equally likely to be infected with chlamydia. Because routine screening of males is not common in general health care practices, their infections may go undetected more often. See related links for references.
