Abstract

In 2013, based on data reported as of April 28, 2014, the rate of reported primary and secondary syphilis in the United States was 5.3 cases per 100,000 population, more than double the lowest-ever rate of 2.1 in 2000. To characterize the recent epidemiology of syphilis in the United States, CDC analyzed data from the National Notifiable Diseases Surveillance System (NNDSS) for cases of primary and secondary syphilis diagnosed during 2005-2013 with a focus on states that reported the sex of sex partners during 2009-2012 to describe reported syphilis among gay, bisexual, and other men who have sex with men (collectively referred to as MSM). During 2005-2013, primary and secondary syphilis rates increased among men of all ages and races/ethnicities across all regions of the United States. Recent years have shown an accelerated increase in the number of cases, with the largest increases occurring among MSM. Among women, rates increased during 2005-2008 and decreased during 2009-2013, with different trends among different racial/ethnic groups. Racial/ethnic disparities in reported syphilis persisted during 2005-2013, likely reflecting social determinants of health, such as socioeconomic status, that might contribute to the burden of syphilis in a community. These findings underscore the need for continued syphilis prevention measures among MSM.
