Immunology discusses HIV/AIDS, including that HIV is the virus that causes AIDS when it destroys T cells in the immune system. The document outlines how HIV enters cells through macrophages, integrates into the cell's nucleus, and hijacks the cell to produce more viruses. It notes that AIDS is diagnosed when the T cell count drops below 200 and that there were over 33 million people infected with HIV globally in 2009, with around 3 million new infections and 2 million AIDS-related deaths that year, making it one of the top causes of mortality.
