Chlamydia cases reached an all-time nationwide high in 2010 with 1.3 million cases of the sexually transmitted disease reported to the Centers for Disease Control and Prevention (CDC), reported MedPage Today. The staggering number is the biggest number ever reported and a 5.1 percent increase over 2009 rates, stated the CDC's annual surveillance report.
The 1,307,893 cases equate to a rate of 426 cases per 100,000 population. The CDC broke down cases into black, Hispanic and white, but failed to account for American Indians/Alaska Natives in its breakdown. Chlamydia proved the highest among black women aged 15-19. It is also predominant among women, although the CDC says this may be attributed to the fact that women are more likely to get tested. Even still, data suggests that most young women are not getting screened. The CDC estimates that there are 2.8 million chlamydia cases annually—more than twice the number actually reported.
According to CDC rates from 2008, the prevalence rate of chlamydia among American Indians/Alaska Natives (808.8 cases per 100,000 population) was 4.7 times higher than that of whites, and lower than the rate among black women (1906.0) and men (841.3).
