 AB    The individuals are distributed in 9 risk groups (adults and children),
       in which an HIV transmission way is predominant. Taking into account a
       simplified graph of the HIV infection evolution, kinetic equations for
       the number of individuals from each risk group--situated in various
       stages of HIV infection--are written. The approximative solutions of
       these equations give us: the characteristic exponents of the temporal
       evolutions of the main and secondary local epidemics; the ratios Ci/Bi
       and Di/Bi of asymptomatically contaminated and dead (as consequence of
       AIDS) versus symptomatically contaminated; the onset of local epidemics
       in various risk groups; the relative amplitude of the secondary local
       epidemics versus the main local ones.
