The American Medical Association voted Tuesday to oppose a decades long ban by the U.S. Food and Drug Administration, which prohibits gay men from donating blood. The FDA ban originated in 1983 in response to the AIDS outbreak, when little was known about the virus and gay men were more likely to have contracted the virus. However, now that the ban is almost 30 years old, some experts say the policy is outdated. HIV and AIDS testing has become standard practice in blood donations to minimize risk to recipients. According to the FDA's website, approximately 1 in 2 million blood transfusions results in an HIV infection.
