Students who have an infectious or communicable disease are allowed to attend school as long as they are able to do so and their presence does not pose an unreasonable risk of harm to themselves or does not create a substantial risk of illness or transmission to other students or employees. If there is a question about whether a student should continue to attend classes, the student shall not attend class or participate in school activities without their personal physician’s approval. Infectious or communicable diseases include, but are not limited to, mumps, measles and chicken pox.
