The prevalence and complexity of infection by P. vivax VK210 and VK247 for Wosera (a) and Mugil (b) study sites. Observed percentages (black) are based upon infection counts. Expected percentages (grey) are based upon a Multiple Kind Lottery strategy for predicting single- and mixed-strain infections. Chi-square analysis showed significant difference between the expected infection values and the observed infections (Wosera: χ2 = 122.12,p > 0.001,3degrees of freedom, Mugil: χ2 = 197.68,p > 0.001, 3 degrees of freedom).
