The NFL's present policy, for anyone interested.
2011 POLICIES FOR NFL PLAYERS
AIDS and HIV
AIDS (Acquired Immunodeficiency Syndrome) and HIV (Human Immunodeficiency Virus the AIDS virus) continue to be important public health issues. Although there is yet no cure for AIDS, many medications are available that slow the progress of the disease. The NFL developed its HIV/AIDS policy based on medical and scientific evidence provided by the Centers for Disease Control and other agencies. Highlights of the policy are summarized below.
HIV-Infected players are not excluded from participation in the NFL. A player with HIV, in consultation with his physician, must make a personal medical decision concerning his participation in the NFL and other activities.
There is no routine testing for AIDS and HIV conducted by the NFL. Additionally, NFL Clubs may only administer an HIV test with the player’s prior, voluntary consent and any such test must be in accordance with applicable state laws.
NFL Clubs will take appropriate precautions and follow universal healthcare procedures to reduce the risk of transmission of illnesses (e.g., Hepatitis B).
The Americans with Disabilities Act and various state laws protect against the acquisition and/or use by employers of information regarding an HIV/AIDS diagnosis.
NFL Clubs are encouraged to advise players and other employees how to obtain private and confidential HIV testing and counseling.
As an aside, I fail to see how NFL clubs can maintain "universal healthcare precautions," which specifically include preventative use of hand hygiene, use of gloves, gown, mask, eye protection, or face shield.
