The human organism expresses retroviruses.
They are beneficial particles needed for immune defense, growth, and tissue repair.
Since retroviruses were observed in the first AIDS patients, it has been postulated - and it has since become firmly established dogma - that retroviruses "cause" AIDS. Anti-retroviral drugs are the treatment of choice for those who have tested positive to the protein which is a signature for retroviruses.
Of course killing the retrovirus also deprives us of the repair and defense functions they perform. And the drugs' side effects are often deadly for AIDS patients.
Perhaps to re-think our approach in this would be a good idea?
