10. A person who has tested HIV positive is diagnosed with AIDS when: the person’s CD4 cell count falls below 200 cells/ml OR CD4 positive T-lymphocyte percentage of total lymphocytes of less than 14% OR the person is diagnosed with any of the following conditions or diseases: Candidiasis of bronchi, trachea, or lungs; Candidiasis, esophageal; Cervical cancer, invasive; Coccidioidomycosis, disseminated or extrapulmonary; Cryptococcosis, extrapulmonary; Cryptosporidiosis, chronic intestinal (>1 month duration); Cytomegalovirus disease (other than liver, spleen, or nodes); Cytomegalovirus retinitis (with loss of vision); Encephalopathy, HIV-related; Herpes simplex: chronic ulcer(s) (>1 month duration); Histoplasmosis, disseminated; Isosporiasis, chronic intestinal (> 1 month duration); Kaposi’s sarcoma; Lymphoid interstitial pneumonitis (in children); Lymphoma, Burkitt’s (or equivalent term); Lymphoma, immunoblastic (or equivalent term); Lymphoma, primary, of brain; Mycobacterium avium complex or M.

11. Patient Zero A study published in the American Journal of Medicine in 1984 traced many of New York City's early HIV infections to an unnamed infected homosexual male flight attendant. Gaëtan Dugas (April 20, 1953 – March 30, 1984) was a French Canadian who worked for Air Canada as a flight attendant. Dugas became notorious as the alleged patient zero for AIDS. Dugas is featured prominently in Randy Shilts's book And the Band Played On, which documents the outbreak of AIDS in the United States. Genetic analysis of HIV provides some support for the Patient Zero theory. Dugas is now believed to be part of a cluster of homosexual men who traveled frequently, were extremely sexually active, and died of AIDS at a very early stage in the epidemic.

32. Table 1 http://www.cdc.gov/mmwr/preview/mmwrhtml/rr5402a1.htm#tab1 -HIV transfers poorly during sexual intercourse or even needle sharing but enough events will lead to transfer. A secondary STD will increase transfer about 10-20 fold during sex.

33. Graph showing HIV copies and CD4 counts in a human over the course of a treatment-naive HIV infection Originally from English Wikipedia. -After a few months the level of HIV in blood has decreased over 100-fold from its peak and remains nearly steady for several years. Still ~10 billion new viruses are made each day during this clinical latent period and over 1 billion T4 helper cells are killed. The very slow decline in T cells over years results from replenishment of essentially all the killed cells each day. The reason for failure after several years remains unclear and highly controversial. One theory suggests that the body simply cannot sustain such a high rate of T-cell production and ultimately levels drop resulting in failure of the entire immune system which is highly dependent on T helper cells.

38. Good: -HAART has been very successful with about 80% of patients responding to treatment in controlled studies. -This therapy has been the primary reason for the decrease in AIDS deaths in the USA and other developed countries. -New single dose pills that contain combinations of different drugs are beginning to be marketed. Bad: -Most under-developed countries where most HIV infections occur do not have access to HAART. -Success rate estimates still leave about 20% of people who don’t respond. -Treatment with drugs ultimately leads to resistant forms and there have been several reports of new viruses resistant to some triple drug regiments. -Drug treatment is complex (10-12 pills a day) and expensive (about $10,000/yr per patient just for drugs). -Several of the drugs have potentially severe side-effects that cannot be tolerated by some patients.
