A communicable disease is an illness that can affect one or more students and/or staff caused by an organism with potential to infect others. This is what is meant by “contagious”.
Most communicable disease events do not require action either by the parent or by the school.However, occasionally there are events that require classroom or school wide attention..Often this will be a single student who has a highly contagious disease (ie., active tuberculosis) or a clustering of symptoms, such as diarrhea and vomiting that is higher than expected for that time of year. This is called surveillance and is the responsibility of the school nurse.
Not every event needs whole school notification. Some events such as bed bugs, lice , scabies may only require classroom.
