HIV dynamic models are illustrated in the form of system of differential equations in most of the existing literatures. Solving the differential equations is very difficult. Then some of the studies followed the Bayesian analysis for estimating the parameter. We obtain the existence of the posterior risk when estimating the parameter. So this paper presents the predictive distribution of the viral load in the HIV dynamic model for pre-determination of the viral replication.

viral load, posterior distribution, predictive distribution.
