Neurosyphilis is now very rare because syphilis is usually treated early. 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. In 2012, the prevalence of syphilis was estimated to be approximately 18 million cases in men and women aged 15-29 worldwide. Among infected patients with Treponema pallidum only 3 to 5% develop neurosyphilis and 5% of those individuals develop tabes dorsalis, 10–20 years later.
