Chlamydia cases number more than 1.4 million
Syphilis cases rise nearly 100% for bi- and homo- sexual men over last 8 years
'Alarming' STD rate
A Center for Disease Control (CDC) report of sexually transmitted diseases (STDs) in the US found that STD cases are at an all-time high. The report, released Nov 2015, found that chlamydia cases numbered more than 1.44 million, up nearly 3% over last year. While both the number of chlamydia cases and the disease rates are the highest ever recorded, the rates for gonorrhea and syphilis are only near 10-yr highs. Gonorrhea cases are up nearly 5% over 2013 and syphilis cases are 15% higher than they were in 2013.
Chlamydia by State
At a rate that is nearly twice the national average of 278 cases per 100,000, the District of Columbia and Alaska have the highest rates of chlamydia, at 508 and 480 cases per 100,000 individuals, respectively. The Western US was the region with the highest rate at 291, followed by the South at 281, and the Midwest and the Northeast at 269 cases per 100,000 people.
STDs by City
The CDC report on STDs also reports data by major metropolitan region. The below figures show the Top 10 cities for each syphilis, gonorrhea and chlamydia rates. If we consider the rates of the all three aforementioned STDs, Memphis, TN has the highest collective rate.
Men sleeping with men
Twenty seven states collect sexual preference data along with STD information, the following figure reflects those data. From 2007 to 2014, bi- and homo- sexual men saw a 100% increase in syphilis cases, rising from 4,000 to just over 8,000 cases. Over the same 8-yr time period men who slept with women saw a 33% increase in syphilis cases, 1,500 to nearly 2,000 cases.
