The Syphilis Epidemic in Connecticut

Abstract

Syphilis rates in Connecticut increased four-fold between 1986 and 1988. During this time there were also signs of a large increase in cocaine use in the state. We studied links between these parallel trends in drug use and syphilis by examining two sources of data: information collected during syphilis case interviews and information from the syphilis screening program at the state's prison for women. As syphilis rates rose, there were large increases in the percentage of women with syphilis who reported prostitution or illicit drug use. In 1988, 41% of women with syphilis reported cocaine use, and 19% reported prostitution; 21% of male heterosexuals with syphilis reported cocaine use, and 31% reported sexual contact with prostitutes. Among incarcerated women, syphilis infection was frequent: of 113 women incarcerated for possession of illicit drugs in 1987-88, 7% were found to be infected with Treponema pallidum, and of 187 women incarcerated for prostitution in these years, 14% were infected. In both groups of incarcerated women studied, cocaine users had the highest syphilis rates, and those who administered drugs nonintravenously had rates similar to those who administered drugs intravenously. We concluded that the syphilis epidemic in Connecticut is related to the increase in use of illicit drugs (primarily cocaine) and that female drug users are at very high risk of syphilis regardless of whether they administer drugs intravenously or nonintravenously. We recommend that syphilis control efforts focus on wider serologic screening and early treatment of drug users, prostitutes, and their sex partners.
