Infectious diseases within American prisons: Infectious diseases within American correctional settings are a concern within the public health sector.  The corrections population is susceptible to infectious diseases through exposure to blood and other bodily fluids, drug injection, poor health care, prison overcrowding, demographics, security issues, lack of community support for rehabilitation programs, and high-risk behaviors.  The spread of infectious diseases, such as HIV/AIDS and other sexually transmitted diseases, hepatitis C (HCV), hepatitis B (HBV), and tuberculosis result largely from needle-sharing, drug use, and consensual and nonconsensual sex among prisoners.  HIV/AIDS and hepatitis C need specific attention because of the specific public health concerns and issues they raise.

Merle Sande: Sande was a professor of Internal Medicine from 1971–1980 at the University of Virginia, where he performed research in mice on bacterial meningitis therapies such as novel antibiotics and corticosteroids.  Dr Sande was Chief of Medical Services at San Francisco General Hospital in 1981 when he recognized a pattern of gay men being admitted with the rare pneumocystis pneumonia.  His efforts on behalf of these patients resulted in the formation of an AIDS ward at San Francisco General Hospital and later an AIDS outpatient clinic.  Teaming with such experts as Julie Gerberding and Paul Volberding he helped to craft what became known as the "San Francisco model" of AIDS therapy, a comprehensive, rational approach to care that avoided the fear and paranoia surrounding the disease at that time.  The model addressed a need for infection-control guidelines, clinical studies and research financing and became a template for AIDS centers nationwide.  Sande helped found to the Gladstone Institute of Virology and Immunology, which performed trials on some of the first anti-retrovirals such as zidovudine.  He also helped to found the Infectious Diseases Institute at the Makerere University College of Health Sciences in Kampala, Uganda a major center for HIV education and research in Africa.  Sande was a professor of Medicine at University of California, San Francisco from 1980–1996, chairman of the department internal medicine at University of Utah from 1996–2005 and Professor of medicine at University of Washington from 2005 until his death and president of the Infectious Diseases Society of America from 1993–4.
