How common is syphilis in the us?

8/100,000 people: He reported rate varies rising from 3/100, 000 inn 2001 to 8/100, 000 in 2009, the last year complete data is available.

More than u think...: Though overall statistics paints a relatively low number, in certain populations such as msm (men who have sex with men) in urban centers, syphilis rates are disturbingly high - in 2010 the cdc estimates it to be 44 times higher than other men and 40 times that of women. It is also important to remember that co-infection with HIV is not uncommon, so get tested for both!

Resources: In 2010, the rate was about 15 cases per 100, 000 population in the U.S. See: http://sgoti.Ws/zqhkwk.
