==Overview==
The rate of primary and secondary syphilis reported in the United States decreased during the 1990s; in 2000, the rate was the lowest since reporting began in 1941. The low rate of infectious syphilis and the concentration of the majority of syphilis cases in a small number of geographic areas in the United States led to the development of the CDCs National Plan to Eliminate Syphilis, which was announced by Surgeon General David Satcher in October 1999 and revised in May 2006.[http://www.cdc.gov/stopsyphilis/plan.htm 2]
In 2012, the incidence of syphilis was estimated to be 6 million cases worldwide. From year 2005 to 2014, the incidence of syphilis in the United States increased from 2.9 to 6.3 cases/100,000/year. The rate of reported cases increased by 15.1% between 2013 and 2014 in the United States.<ref name=CDC>https://www.cdc.gov/std/stats14/surv-2014-print.pdf Accessed on September 16, 2016</ref> Syphilis incidence increased in every region of the Untied States in 2014, with the highest rate in the West and lowest rate in the Midwest. In 2012, the [[prevalence]] of syphilis was estimated to be approximately 18 million cases in men and women aged 15-29 worldwide.<ref name="pmid26646541">{{cite journal| author=Newman L, Rowley J, Vander Hoorn S, Wijesooriya NS, Unemo M, Low N et al.| title=Global Estimates of the Prevalence and Incidence of Four Curable Sexually Transmitted Infections in 2012 Based on Systematic Review and Global Reporting. | journal=PLoS One | year= 2015 | volume= 10 | issue= 12 | pages= e0143304 | pmid=26646541 | doi=10.1371/journal.pone.0143304 | pmc=4672879 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=26646541  }} </ref> The incidence and prevalence of syphilis may be affected by age, gender, race, sexual behavior and geographical distribution.<ref name=CDC>https://www.cdc.gov/std/stats14/surv-2014-print.pdf Accessed on September 16, 2016</ref><ref name="pmid23403598">{{cite journal| author=Satterwhite CL, Torrone E, Meites E, Dunne EF, Mahajan R, Ocfemia MC et al.| title=Sexually transmitted infections among US women and men: prevalence and incidence estimates, 2008. | journal=Sex Transm Dis | year= 2013 | volume= 40 | issue= 3 | pages= 187-93 | pmid=23403598 | doi=10.1097/OLQ.0b013e318286bb53 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=23403598  }} </ref><ref name=WHO2012>http://apps.who.int/iris/bitstream/10665/85376/1/9789241505895_eng.pdf?=1 Accessed on September 16, 2016</ref><ref name="pmid23049658">{{cite journal| author=Purcell DW, Johnson CH, Lansky A, Prejean J, Stein R, Denning P et al.| title=Estimating the population size of men who have sex with men in the United States to obtain HIV and syphilis rates. | journal=Open AIDS J | year= 2012 | volume= 6 | issue=  | pages= 98-107 | pmid=23049658 | doi=10.2174/1874613601206010098 | pmc=3462414 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=23049658  }} </ref><ref name="pmid17463387">{{cite journal| author=Heffelfinger JD, Swint EB, Berman SM, Weinstock HS| title=Trends in primary and secondary syphilis among men who have sex with men in the United States. | journal=Am J Public Health | year= 2007 | volume= 97 | issue= 6 | pages= 1076-83 | pmid=17463387 | doi=10.2105/AJPH.2005.070417 | pmc=1874206 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=17463387  }} </ref><ref name="pmid6893897">{{cite journal| author=Judson FN, Penley KA, Robinson ME, Smith JK| title=Comparative prevalence rates of sexually transmitted diseases in heterosexual and homosexual men. | journal=Am J Epidemiol | year= 1980 | volume= 112 | issue= 6 | pages= 836-43 | pmid=6893897 | doi= | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=6893897  }} </ref>

Overview

In 2012, the incidence of syphilis was estimated to be 6 million cases worldwide. From year 2005 to 2014, the incidence of syphilis in the United States increased from 2.9 to 6.3 cases/100,000/year. The rate of reported cases increased by 15.1% between 2013 and 2014 in the United States.[1] Syphilis incidence increased in every region of the Untied States in 2014, with the highest rate in the West and lowest rate in the Midwest. In 2012, the prevalence of syphilis was estimated to be approximately 18 million cases in men and women aged 15-29 worldwide.[2] The incidence and prevalence of syphilis may be affected by age, gender, race, sexual behavior and geographical distribution.[1][3][4][5][6][7]

Epidemiology

Incidence

  • Worldwide incidence of syphilis:
    • 2004: approximately 12 million cases[8]
    • 2008: approximately 10.9 million cases[9][10][11]
    • 2012: approximately 6 million cases[2]
  • Incidence of syphilis in the United States:
    • From 2005 to 2014, the incidence of primary and secondary syphilis increased from 2.9 to 6.3 cases/100,000/year.
    • From 2009 to 2014, the incidence of late and latent syphilis increased from 5.6 to 7.4 cases/100,000/year.
    • The rate of reported cases increased by 15.1% between 2013 and 2014.[1]
    • Syphilis incidence increased in every region of the Untied States in 2014, with the highest rate in the West and lowest rate in the Midwest.

Prevalence

  • In 2008, the prevalence of syphilis was estimated to be 36.4 million cases worldwide.[9]
  • In 2012, the prevalence of syphilis is estimated to be 18 million cases in men and women aged 15-29 worldwide.[2]
  • In 2014, the prevalence of syphilis in the United States was estimated to be 20 cases/100,000 individuals.[1]

Demographics

The incidence and prevalence of syphilis may be affected by the following demographic factors:[1][4]

Age

In 2014, the highest rate of primary and secondary syphilis in the United States was seen in age groups 20-24 years and 25-29 years.[1][3]

Gender

  • There is increased incidence of primary and secondary syphilis in men who have sex with men (MSM).
    • In 2014, 61% of 19,999 total reported cases of primary and secondary syphilis were estimated to be among MSM.[1][4][5][6][7]

Race

  • Syphilis is more prevalent in the African American population as compared to other racial groups.[2]
  • In 2014, the highest incidence of primary and secondary syphilis in the United States was reported to be in the African American population and the lowest incidence was observed in Caucasisans, Asians and multiracial groups.[1]
