Chlamydia is, in fact, the most commonly reported sexually transmitted disease in the United States. According to data from the Centers for Disease Control and Prevention (CDC), Chlamydia trachomatis infection consistently has the highest rate of reported cases among STDs. It is highly recommended that high-risk groups, such as adolescents and women with multiple sex partners, undergo regular screening for chlamydia due to its prevalence and potential complications if left untreated.
