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.
这些个体被分为9个风险组（成人和儿童），每个风险组都有一种主要的HIV传播方式。考虑到HIV感染演变的简化图表，针对处于HIV感染不同阶段的每个风险组中的个体数量，写出了动力学方程。这些方程的近似解为我们提供了：主要和次要局部流行时间演变的特征指数；无症状感染与死亡（因艾滋病所致）个体数量与有症状感染个体数量的比值Ci/Bi和Di/Bi；不同风险组中局部流行的起始情况；次要局部流行相对于主要局部流行的相对幅度。
