This document contains guidelines for developing policies and procedures related to chronic infectious diseases, as recommended by the Illinois Task Force on School Management of Infectious Disease. It is designed to help school personnel understand how infectious diseases can be transmitted, and to assist school districts in the development and implementation of school programs that will meet the needs of students who have chronic infectious diseases while preventing the spread of such diseases in the school setting. A chapter on general management of infectious disease focuses on: establishing prevention procedures; maintaining a safe, clean, and healthful school environment; cleaning up body fluid spills; developing special procedures for early childhood, day care, and special classroom settings; and selecting an appropriate disinfectant. Specific diseases covered include: congenital rubella syndrome, hepatitis B, cytomegalovirus (CMV) infections, acquired immunodeficiency syndrome (AIDS) and AIDS related complex (ARC), and herpes simplex. Each disease is described along with its mode of transmission, its prevention, and the management of infectious students in the classroom. (JDD)
