Fast facts about the most common STDs
Chlamydia:
* Chlamydia is the most prevalent sexually transmitted infection in the US.
* In 2008, over 1.2 million reported cases of Chlamydia (1,210,523) were reported to the CDC
o Note: CDC research indicates that most individuals infected with Chlamydia never experience symptoms. Because of this, many infections go unreported. Based on this knowledge, the CDC estimates that there are roughly 2.8 million actual cases of infection in the US every year.
* In the US, the rate of Chlamydia infection is about 401.3 cases per 100,000 people.
* Women, especially younger women and those that are minorities, seem to be most at risk for Chlamydia infection. In 2008, young women aged 15 to 19 years comprised the highest numbers of reported cases (342,875) and highest rates of Chlamydia (3,275.8 per 100,000 females) infection
* For those young women aged 20 - 20, there were 323,696 reported cases of infection in 2008
* Chlamydia infection among men is reported to be on the rise. Between 2004 and 2008, there was a 45% increase in infection among men.
Gonorrhea:
* Gonorrhea is the second most common Sexually Transmitted Infection (also referred to as an STD) in the United States.
* In 2008, there were 336,742 reported cases of Gonorrhea infection
o Note: CDC research indicates that many individuals infected with Gonorrhea never experience symptoms; therefore, their infection goes unreported. Because of this, the CDC estimates that there are roughly twice as many Gonorrheal infections annually, over what is actually reported.
* The rate of infection in the US is 111.6 cases per 100,000 people.
* Since 2000, rates of infection between men and women have remained somewhat similar. In 2008, rates of infection among men and women were as follows:
o Women: 119.4 cases per 100,000 people
o Men: 103.0 cases per 100,000 people
* Young women and teenage girls seem to have the highest rate of Gonorrhea infection. In 2008, the infection rates of teenage girls and young women were as follows:
o Girls age 15 to 19 years: 636.8 cases per 100,000 girls
Women age 20 to 24 years: 608.6 cases per 100,000 females
Syphilis:
* Although previously on the brink of complete elimination less than 10 years ago, Syphilis has once again become a health threat as rates of infection have steadily been on the rise since 2001.
* In 2008 there were the highest number of reported cases since 1995. In fact, there were 13,500 cases of primary and secondary Syphilis that year alone.
o The rate of infection in 2008 rose 18% from 2007. Previously at a rate of 3.8 cases of infection per every 100,000 people, Syphilis infection rose in 2008 to an estimated 4.5 cases per every 100,000 individuals.
* Syphilis infection continues to be reported highest within the gay male community (men having sex with other men). In 2008, CDC data reported 63% of reported Syphilis infections were among gay and bisexual men, as opposed to only 4% of infections back in 2000.
* The rate of infection among women in the US increased 36% from 2007 to 2008. In 2007, there was an estimated 1.1 cases per every 100,000 females, while in 2008 there was an estimated 1.5 infections per every 100,000.
In 2008, there were 431 cases of congenital Syphilis (transmission from mother to infant during childbirth) reported to the CDC. These cases constitute a rate of infection of 10.1 Syphilis transmissions per 100,000 live births.
