Fig 2. Proportion of women in each serologic category.

The percentage of each serostatus is shown for the total cohort as well as subsets of the cohort stratified by LMP, indicating which pregnancies occurred during dates inclusive of peak ZIKV transmission (“Peak”) or after that period (“Post-peak”). Naïve specimens were excluded for this analysis. 183 of the 187 subjects had data for LMP, n = 108 before 30 Sept 2016 and n = 75 after 30 Sept 2016. LMP, last menstrual period.
