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. 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. The incidence and prevalence of syphilis may be affected by age, gender, race, sexual behavior and geographical distribution.
