Proportion of MIs is the percentage of patients infected with multiple parasite genotypes. He is the expected heterozygosity index. % of identical infections is the percentage of single-genotype infections that share alleles at all the 24 SNPs genotyped. Multilocus LD (all genotypes) is multilocus linkage disequilibrium estimated by including all identical parasite genotypes while multilocus LD (unique genotypes) is that estimated by including single representatives of identical parasite genotypes. Error bars are standard deviations. We observed no multilocus linkage disequilibrium (p > 0.05) and no significant change in the proportion of MIs, He and % of identical infections over time.
