Communicable Diseases: Exposure Notices and Facts Sheets

A communicable disease is an infectious disease that can be transferred/transmitted from an infected person to another individual. Organisms like bacteria, viruses, and parasites cause infectious diseases. Illness caused by an infectious disease is a common occurrence in students. These notices address various infectious diseases often seen in students.

Most cases of illness are isolated to one student, but occasionally an outbreak of a particular disease can occur in a school.  The law requires school personnel to report to the local public health agency a list of specific reportable disease or conditions.  Notices included in this section can be downloaded and sent home to parents.
