diseases often coevolve with their hosts (e.g. myxomatosis and rabbits). Based on this, what do you predict will
happen to the effects of HIV (virus that causes the disease AIDS) on humans
over time and why?
destroys human immune system. Once a person’s viral load starts rising to
higher and higher levels, this is a sign that the immune system is worsening;
the disease is reaching a more advanced stage over time. In the final
stage of HIV, the immune system is rigorously compromised. Infections become more
and worse. CD4+ T-cell counts fall considerably, and viral load increases considerably.
When a person’s CD4+ T-cell count falls under 200 cells per cubic millimeter of
blood and he or she is diagnosed with a stage-4 HIV-related condition (for
instance tuberculosis, cancer, and pneumonia), the HIV has progressed to
Acquired Immunodeficiency Syndrome (AIDS). Once HIV progresses to AIDS, a
person is more expected to die.
