Syphilis
Human immunodeficiency virus?

HIV
AIDS
-? damages the immune system so it interferes w/ the body’s ability to fight organisms that cause disease
-? is transmitted blood, semen, or vaginal secretion: sexual activity, blood transfusions, needles. Etc
HIV
-no cure
-meds slow progression; combine at least 3 drugs from 2 different classes to avoid creating HIV strains that are resistant to a single drug.
