By examining available data on more than 60,000 men and women who tested positive for chlamydia between 2007 and 2009 at facilities participating in CDC's Infertility Prevention Project in New York, New Jersey and the U.S. Virgin Islands, analysts with Cicatelli Associates, Inc. found that just 14 percent of men and 22 percent of women were retested within 30-180 days. Of those who were retested, a significant proportion again tested positive (25 percent of men and 16 percent of women).
