Immunological failure is identified from the estimation
of certain parameters of a mathematical model
of HIV infection dynamics. This identification is supported
by clinical research results from an original clinical trial.
Standard clinical data were collected from infected patients
starting highly active antiretroviral therapy (HAART) after
just 1 month of therapy initiation and were used to carry out
the model identification. The early diagnosis is shown to be
consistent with patient monitoring after 6 months.
