Figure 5. Eosinophil and hemoglobin concentrations in US-bound Myanmar refugees at 3 camps along the Myanmar–Thailand border who were monoinfected with Ancylostoma ceylanicum (n = 24) or Necator americanus (n = 143) hookworm at baseline, Thailand, 2012–2015. Those co-infected with both hookworms or Strongyloides stercoralis, Ascaris lumbricoides, or Trichuris trichiura roundworms were excluded from analysis. Horizontal line indicates geometric mean. Significance was calculated by Mann-Whitney test. A) The geometric mean eosinophil cell concentration was significantly higher in those with A. ceylanicum monoinfection (8.49 × 108 cells/L, 95% CI 5.98–12.0 × 108 cells/L) than those with N. americanus monoinfection (3.44 × 108 cells/L, 95% CI 2.92–4.05 × 108 cells/L) (***p<0.001). B) The geometric mean hemoglobin level of the 2 groups was not significantly different.
