Answer:
AIDS affects our immune system, that itslef is a serious matter. The AIDS virus being a retrovirus, invades the host cells in a very complicated and baffling manner.
Scientists have not been able to understand the behaviour of the virus as it hides out in certain tissues of the body. Then there are too many strains of the virus. The virus mutates so often that no cure works for very long or at all. HIV is so complicated that it implants itself into our genome or DNA and keeps replicating, tricking our immune system to produce more HIV viruses instead of producing T-cells, which are vital for conducting a proper immune response to a viral or bacterial invasion.
