    Chlamydial infections are common among young women and can lead to serious reproductive health complications. We assessed the risk of reported repeat chlamydial infection among young women in Louisiana and time interval between infections by age and race/ethnicity.


    We analyzed surveillance data on chlamydial infections reported among women in Louisiana from January 1, 2000 to December 31, 2015. Multiple reports for the same person were matched using unique codes. Chlamydial infections reported more than 30 days after a previous positive test were considered new infections. Women aged 15–34 years at first infection during 2000–2012 were censored after three years or after they had a repeat infection. Cumulative incidence and incidence rate of repeat chlamydial infection among women were determined by year of first infection. Race- and age-specific results were obtained using stratified analyses.


    One in four women diagnosed with a chlamydial infection at 15–34 years of age in Louisiana had a reported repeat infection in three years or less. Risk of repeat infection increased for younger women, racial/ethnic minorities, and women in more recent cohorts. Young black women aged 15–19 years in 2012 had the highest risk (44%). Black women also had shorter intervals between infections than white women.


    Repeat chlamydial infections were common, especially among young black women. The true number is likely higher because surveillance data only count infections that were detected and reported. Comprehensive prevention strategies are needed to address high rates of repeat chlamydial infections among women.
