as 4.6 months. The longest was reported by Xu et al. as 10.9 months.15 The remaining two studies by Niccolai et al.25 and Burstein et al.17 reported median time to reinfection as 5.2 months and 6 months, respectively. GENDER-SPECIFIC PREVALENCE AND INCIDENCE RATES Limited information was available on gender-specific reinfection rates. Over half of the studies excluded males. Of the five studies that included both sexes, three analyzed rates stratified by sex. Burstein et al. studied adolescents aged 12-19 to determine screening practices within the Kaiser Permanente Mid-Atlantic States (KPMAS) system and the positive chlamydia results from those screenings, reviewing medical histories of adolescents who were screened at least twice. 17 Researchers reported a chlamydia reinfection prevalence rate of 17.1% and 11.1% among females and males, respectively.17 Only 1.5% of the males in the KPMAS system were screened for chlamydia.17 Orr et al. reported a female reinfection prevalence rate of 73% by 7 months and a male reinfection rate of 60% by 7 months among high-risk adolescents aged 14-21 from STD clinics.16 Finally, Michelson et al., who recruited lab confirmed chlamydia from a county health department, reported reinfection incidence rates of 3,982 female cases and 2,223 male cases per 100,000 person years.14 Researchers did not include asymptomatic men in their analysis, limiting the population pool.14 Reitmeijer et al. included both genders but did not stratify reinfection by age.20 Anshuetz et al. evaluated only adolescents, but did not stratify reinfection rate by gender.28
