Acquired Immunodeficiency Syndrome (AIDS)
People with AIDS
Are highly susceptible to opportunistic infections and cancers that take advantage of an immune system in collapse
Because AIDS arises from the loss of helper T cells
Both humoral and cell-mediated immune responses are impaired
The loss of helper T cells
Results from infection by the human immunodeficiency virus (HIV)
The spread of HIV
Has become a worldwide problem
The best approach for slowing the spread of HIV
Is educating people about the practices that transmit the virus
