Ratios of Emergence as HIV/AIDS Prevalence Increases: We investigated the emergence and dominance of resistant strains as HIV/AIDS prevalence increased from 0%–30%, and we present results for the entire population, and for HIV/AIDS+ hosts only. Irrespective of the initial fitness of the q-strain, we observe increasing q-strain success as HIV/AIDS prevalence increases. (a,b) Emergence in the total population with (a) cf = 0.5 and (b) cf = 1.2; (c,d) Emergence in the HIV+ infective population with (c) cf = 0.5 and (d) cf = 1.2; (e,f) Relative emergence among (e) total population and (f) HIV+ infectives.
