In the nearly 4 years since the initial publication of the model policy "Communicable Diseases and the Enrolled Student" in January 1986, the statistics, recommendations, and even the terminology of Acquired Immune Deficiency Syndrome (AIDS) have changed significantly. In light of the new information, the model policy, recommended for consideration or adoption by schools and school districts in Iowa, has accordingly been revised. Delineated within this document are changes in: (1) the admission and enrollment policy; (2) confidentiality of medical status as a Human Immunodeficiency Virus (HIV)-infected student; (3) health education and universal precautions; and (4) the appeal and review policy. Because blood and bodily fluids of all persons are considered potentially infectious for HIV, Hepatitis B Virus, and other bloodborne pathogens, "Universal Blood and Body Fluid Precautions" should be consistently followed. Appended is a listing of universal precautions for use in a school system. (KM)
