Abstract
Any component exposed to shocks which cause damage to the component is likely to fail when the total cumulated damage exceed a level called threshold. When the immune system does not accumulate the increase in shock which is the inter-arrival time, the expected life time of the human system will reach the threshold. CD4 counts are observed with three variables of time, namely Platelet Count, Prothrombin Time and Activated Partial Thromboplastin Time. Through shock model the CD4 count is being studied and the data collected in Pondicherry region is been fitted for the time to break down of the infected person.
