Document Summary
Ch 10: the resurgence of infectious disease (biomedical science) Attaches to rna, which is mistakenly replicated => multiplies => can mask itself as a regular cell. Human immunodeficiency virus -> leads to aids. Aids: disease in which there is a severe loss of the body"s cellular immunity, greatly lowering the resistance to infection and malignancy. Now many drugs are available, but no cure. Used to be a problem; no longer in u. s. Probably originated in africa (best current speculation) Cross species transmission from monkeys or apes. Spread in human populations due to a disruption of traditional lifestyles. Spread to western countries due to changing patterns of sexual behavior and international travel. Factors that lead to emergence of new infectious. Human activities that cause ecological damage and close contact with wildlife. We are making new things interact (mutations) People think animals are awesome (they are); but they don"t think of the consequences.
