Abstract: CorrectionsWe found a few issues in our original paper that require correction.First, we did not state a basic assumption used to derive an expression for R * .In our infection model we included the term ω to account for the rate of 'natural removal' from the population (i.e.cessation of sexual activity that is not related to HIV-specific mortality).We did not clearly state that our derivations assume that ω = 0.This assumption was justified by the fact that δ 1 is always going to be much larger than ω for HIV such that the probability of an infected case being removed before reaching the second stage of infection is very small.For example, if we assume that the acute stage of infection lasts 2 months and that an average person is sexually active for 30 years, then the probability of being removed before progressing to the second stage is less than 0.005.We chose to assume ω = 0 but did not clearly state this assumption.Second, there is a typo in the original expression for R * where the terms β 1 and β 2 were omitted.The correct expression for R * is
