April is STD Awareness Month, an annual observance to
raise public awareness about the impact of sexually transmitted diseases (STDs)
on the lives of Americans and the importance of individuals discussing sexual
health with their health care providers and if sexually active, their partners.
Many of those who are infected don't know it. Many STDs do not have any symptoms. The only way to know for sure whether you have an STD is to get tested.
Chlamydia remains the most commonly reported infectious disease in the United States. In 2006, 1,030,911 chlamydia diagnoses were reported, up from 976,445 in 2005. Even so, most chlamydia cases go undiagnosed.
It is estimated that there are approximately 2.8 million new cases of chlamydia in the United States each year.
Women, especially young women, are hit hardest by chlamydia. Studies have found that chlamydia is more common among adolescent females than adolescent males, and the long-term consequences of untreated disease are much more severe for females. The chlamydia case rate for females in 2006 was three times higher than for males.
Because chlamydia is most common among young women, CDC recommends annual chlamydia screening for all sexually active women under age 26, as well as older women with risk factors such as new or multiple sex partners.3 Data from one study in a managed care setting suggest that chlamydia screening and treatment can reduce the incidence of pelvic inflammatory disease (PID) by over 50 percent. Unfortunately, many sexually active young women are not being tested for chlamydia, in part reflecting a lack of awareness among some providers and limited resources for screening. Research has shown that simple changes in clinical procedures, such as coupling chlamydia tests with routine pap testing, can sharply increase the proportion of sexually active young women screened.6 Increased prevention screening efforts are critical to preventing the serious health consequences of this infection, particularly infertility.
