The competition was not close. The STI study referenced by the CDC estimated that 50 percent of the new infections in 2008 occurred among people in the 15-to-24 age bracket. In fact, of the 19,738,800 total new STIs in the United States in 2008, 9,782,650 were among Americans in the 15-to-24 age bracket. By contrast, there were 1,524,092 bachelor’s degrees awarded in the United States in the 2007-2008 school year, according to the National Center for Education Statistics. That means the total number of new STIs in 2008 outpaced the total number of new bachelor’s degrees by nearly 13 to 1, and the number of new STIs among Americans in the 15-to-24 age bracket outnumbered new bachelor’s degrees by more than 6 to 1.
While the CDC estimates that there were 19.7 million new STIs in the United States in 2008, data published by the Bureau of Labor Statistics indicated that the total number of people employed in the country actually declined by 2.9 million during that year. The CDC said the new venereal infections contracted each year cost the nation about $16 billion. “CDC’s new estimates show that there are about 20 million new infections in the United States each year, costing the American healthcare system nearly $16 billion in direct medical costs alone,” said a CDC fact sheet.
The CDC study—“Sexually Transmitted Infections Among U.S. Women and Men: Prevalence and Incidence Estimates, 2008”—was published in the March edition of Sexually Transmitted Diseases, the journal of the Sexually Transmitted Diseases Association. The study distinguishes between “incidences” of a disease, which is the number of new infections in a year, and the “prevalence,” which is the total number of new and existing infections. “In 2008, there were an estimated 110 million prevalent STIs among women and men in the United States,” said the study. “Of these, more than 20% of infections (22.1 million) were among women and men aged 15 to 24 years.
Approximately 19.7 million incident infections occurred in the United States in 2008; nearly 50% (9.8 million) were acquired by young women and men aged 15 to 24 years.” The study focused on estimating the incidences of sexual transmission of particular diseases as opposed to other forms of transmission. For example, it did not include HIV infections that were not sexually transmitted. It also counted the number of infections rather than the number of people infected–recognizing that a single individual could have multiple infections.
