CDC: Sexually transmitted infections increase in 2011
Reports of the sexually transmitted infections (STI), chlamydia and gonorrhea showed significant increases from 2010 to 2011, according to the 2011 Sexually Transmitted Diseases Surveillance report released Thursday by the Centers for Disease Control and Prevention (CDC).
According to the annual report, in 2011, a total of 1,412,791 cases of Chlamydia trachomatis infection were reported to the Centers for Disease Control and Prevention (CDC).
This case count corresponds to a rate of 457.6 cases per 100,000 population, an increase of 8.0% compared with the rate of 423.6 in 2010.
CDC officials say (the 1.4 million cases) is the largest number of cases ever reported to CDC for any condition.
Rates of chlamydial infections among women have been increasing annually since the late 1980s. In 2011, the overall rate of chlamydial infection in the United States among women (648.9 cases per 100,000 females) was over two and a half times the rate among men (256.9 cases per 100,000 males), reflecting the large number of women screened for this disease, says federal health officials.
Differences of rates of chlamydia were not only seen in gender, but there were also racial differences. In 2011, the chlamydia rate in blacks was over seven times the rate in whites.
Alaska was the state with the highest rate of chlamydia in the nation with 808 cases per 100,000 population, while New Hampshire was the lowest with 228.6 cases per 100,000 population.
Gonorrhea, which experienced a massive decline from the mid-70s to the mid-90s, has been increasing in recent years. In 2011, The CDC reported 321,849 gonorrhea infections. The rate increased 4% to 104.2 cases per 100,000 in 2011 from 100.2 in 2010.
Gonorrhea is most reported from the southern states.
Gonorrhea, like chlamydia, showed differences in rates between the sexes and races. In 2011, the gonorrhea rate in women was 108.9 cases per 100,000 population compared with a rate of 98.7 in men. As with chlamydia, gonorrhea rates in women were highest among those aged 15–24 years. In men, they were highest among those aged 20–24 years.
The gonorrhea rate in blacks was 17 times the rate in whites last year, according to the Surveillance report.
Louisiana ranked highest in the country with a 202.3 rate per 100,000 population. Vermont was the lowest with 7.7 case per 100,000 population.
The report also shows some increases in syphilis cases in 2011, with much of the increase attributed to men who have sex with men (MSM).
