Expert Answer
The patient is suffering from Acquired Immuno Deficiency Syndrome (AIDS). The causal organism is Human Immunodeficiency Virus (HIV).
HIV infects Helper T-cells. HIV enters Helper T-cells where it replicates and produces progeny viruses. The progenies liberated by lysis of host T-cells attack other Helper T-cells. Repeated attacks result in progressive decrease in the number of T-cells and thus reducing immunity.
