    Mean average pairwise Hamming distance (APHD) of HIV-1 Env SGA/S sequences distinguishes between single and multiple founder viruses.

    <p><b>(A)</b> A training set of SGA/S Env sequences derived from 127 previously published acute HIV-1 infected subjects illustrating a wide range of <i>env</i> diversity. The APHD is calculated using a sliding window of 120bp with a step size of 21bp. The mean APHD is plotted according to Fiebig stages as defined by HIV-1 clinical laboratory test results. <b>(B)</b> A classifier based on a logistic regression segregated 127 subjects into single or multiple infections and correctly assigned 97% of subjects into the respective groups. Each point corresponds to an individual subject with the number of subjects denoted on the x-axis in parenthesis under each Fiebig stage.</p
