FIG. 4.

Age distribution among case patients (n = 24; black boxes) and non-case patients (n = 378; white boxes) who participated in part 1 and/or 2. The age of one non-case patient was unknown. Fifty (65.8%) of the 76 persons in the 21- to 30-year age range were women; they are the predominant figures in Haitian households and thus the adults most likely to be home. The percentages (numerator/denominator) of persons in each age group infected with Cyclospora are provided. The prevalence for children ≤10 years of age (i.e., those in age groups of 0 to 5 and 6 to 10 years) was 13.3% (20 of 150).
