The US Centers for Disease Control and Prevention (CDC) released the latest data about sexually transmitted infections (STI) Thursday in the Sexually Transmitted Disease Surveillance, 2010 publication.
According to the report, the surveillance information in this report is based on the following sources of data: (1) notifiable disease reporting from state and local STD programs; (2) projects that monitor STD prevalence in various settings, including regional Infertility Prevention Projects, the National Job Training Program, the STD Surveillance Network, and the Gonococcal Isolate Surveillance Project; and (3) other national surveys implemented by federal and private organizations.
In 2010, chlamydia hit record numbers. 1,307,893 cases of sexually transmitted Chlamydia trachomatis infection were reported to the CDC, this is an increase of greater than 5% from the previous year.
The overall rate of chlamydial infection in the United States among women (610.6 cases per 100,000 females) was over two and a half times the rate among men (233.7 cases per 100,000 males).
Alaska had the highest rate of Chlamydia with 861.7 cases per 100,000 population (national average: 426/100,000 population). New Hampshire had the lowest rate (185.9/100,000 population).
As far as raw numbers, California reported the most cases with 150,443.
In 2010, a total of 309,341 cases of gonorrhea were reported in the United States, which corresponds to a rate of 100.8 cases per 100,000 population.
Other key stats concerning gonorrhea in the United States include: 1) the gonorrhea rate in women was 106.5 cases per 100,000 population compared with a rate of 94.1 in men, 2) the gonorrhea rate in blacks was 18.7 times the rate in whites and, 3) In 2010, 9 isolates with decreased susceptibility to cefixime were reported.
The state with the highest rate of gonorrhea in 2010 was Mississippi with 209.9 per 100,000 population. Texas is the state with the most reported cases last year with 31,788.
After decades of declining numbers, syphilis is experienced a resurgence, going up every year from 2001 to 2009. However, in 2010, the overall rate decreased for the first time in 10 years (the syphilis rate fell 1.6 percent from 2009 to 2010).
There was a total of 13,774 cases of Primary & Secondary syphilis reported to CDC in 2010.
The report notes:
Although wide disparities exist in the rates of STDs among racial and ethnic groups, these disparities have decreased for syphilis over the past 10 years. In 2010, the P&S syphilis rate among blacks was eight times the rate among whites, which is substantially lower than the disparity observed in 1999, when the rate among blacks was 24 times higher than the rate among whites.
However, the data shows that syphilis rates increased 75% among black men aged 15–19 years and 134% among those aged 20–24 years during the period of 2006 to 2010.
Louisiana had the highest rates of syphilis in the country with 12.2 cases per 100,000 population. Wyoming had no reported cases of syphilis in 2010.
The report goes on to say that sexually transmitted infections cost the nation’s health care system $17 billion annually.
