CDC reports finds sexually transmitted infections on the rise among MSM
Cases of sexually transmitted infections other than HIV are on the rise in the US, particularly among men who have sex with men (MSM).
According to a Centers for Disease Control and Prevention overview of national surveillance data for 2015, men accounted for over 90% of all cases of syphilis and of these 81.7% were MSM.
Overall, in 2015 a total of 23,872 syphilis cases were reported nationally, a 19% increase from 2014.
During 2011–2015, the chlamydia rate in men increased 20%, compared with a 0.3% increase in women during this period.
However, this is due to the fact that MSM are increasingly being tested for chlamydia infection.
Gonorrhea rates among both men and women increased in every region of the United States.
The extent of the increase among males suggest either increased transmission or increased screening among MSM, or both.
