Abstract
In this paper we investigate the effects of variable infectivity on th e spread of HIV in a heterosexual population where pair formation and separation are taken into account. We calculate the basic reproduction ratio as a function of the number of new partners during the infectio us period, keeping the total number of contacts fixed. Numerical evide nce suggests that the basic reproduction ratio decreases for variable infectivity if the average infectivity is kept constant.
