  1. aThe multiplicity of infection (MOI) was calculated by dividing the total number of P. vivax clones by the number of PCR-positive isolates; H E , the expected virtual heterozygosity (the chance of drawing a pair of alleles differs from each other) using the following formula: H E  = [n/(n − 1)] × (1 − ∑p 2i ), where pi is the frequency of the ith allele and n is the number of isolates analysed
