โœฆ Synopsis

It is shown that the concept of the basic reproduction number R, which has arisen in the theory of acute air-borne infections, need8 essential modifications when it is applied to chronic, eexnally transmitted infections. A new definition of R is given. which takes into account the aging of the infected person and its partners during the course of the infection. Thereby the impact of age preference in sexual choice on the ~preed of HIVIAIDS can be quantified with little computational effort. It turns out that for low-riak groups, R h by far smaller than conventional calculation would suggest, and that the frequency of partnershipa between people with distant ages exerts greater influence on R than the infection probability per contact and the number of successive partnership6 within the infectious period. It is euggested that a high incidence of partnerships between older men and very young women is a major reaeon for the AIDS epidemic in Africa.
