Clinicalinfo is an online resource offering treatment information to health care providers caring for people with HIV and AIDS-related illnesses, including prevention and treatment of HIV-related opportunistic infections, prevention of mother-to-child transmission during pregnancy, and information on the prevention of HIV transmission from occupational exposure. Clinicalinfo is also a resource to refer patients to information about their continuum of care. This includes access to information about FDA-approved and investigational HIV/AIDS related drugs, available in both patient and health professional versions.
