Abstract
The number of persons with early syphilis who donated blood between 1995 and 2000 in the United States was estimated using data collected in the National Electronic Telecommunication System for Surveillance (NETSS). To distinguish paid from volunteer donors, cases reported in 2000 were analyzed. For the 6 years, 22 primary, 81 secondary, and 413 early latent syphilis cases were identified through donation screening. In 2000, 69 cases of early syphilis were identified through donation screening in 16 states. In 6 states that reported 53 of these cases, 31 case subjects (58%) were volunteer donors and 22 (42%) were paid donors. Eighty-one percent of volunteer donors and 64% of paid donors reported no risk factors for syphilis. After adjustment for variation in NETSS use, it was estimated that, over the 6 years, approximately 1200 cases of early syphilis were detected nationally through donation screening, and 58% of the case subjects were volunteer donors.
