In 2002, Trask et al. published a study showing that a highfrequency of HIV transmissions in Lusaka, Zambia occurred betweenmarriage partners. Specifically, they studied a cohort of marriedcouples where, at the beginning of the study, one partner wasinfected and the other was not. Later, the uninfected partnerbecame infected. If you were doing this study, how could you usephylogenetic methods to determine whether the newlyinfected individual was likely infected by his/her partner? Brieflydescribe your study design and results that would support andresults that would refute (you can use drawings if you wish) thepartner-partner transmission scenario.
