Predictors of disease progression in HIV infection: a review

Reviver submitted, created time 1 year 3 months (www.aidsrestherapy.com)

"During the extended clinically latent period associated with Human Immunodeficiency Virus (HIV) infection the virus itself is far from latent. This phase of infection generally comes to an end with the development of symptomatic illness. Understanding the factors affecting disease progression can aid treatment commencement and therapeutic monitoring decisions. An example of this is the clear utility of CD4 count and HIV-RNA viral load for disease stage and progression assessment
