Communicable Disease

Understanding Communicable Diseases in Our School Community

Communicable diseases are illnesses that can spread from one person to another, affecting students and staff. These diseases are caused by organisms, such as viruses or bacteria, that have the potential to infect others.

When is Action Required?

Not all communicable diseases require action from parents or the school. In many cases, a student may contract an illness that does not pose a significant risk to others, and no further steps are needed. However, there are instances when additional attention is necessary, either within a classroom or across the entire school community. If further action is required, such as in the case of a highly contagious disease or an unusual increase in specific symptoms, the school will send out a notification letter. This letter will be distributed either to the affected classroom or to the entire school community, depending on the situation.

Cluster Definition

To ensure the safety and well-being of our students and staff, Boston Public Schools (BPS) has a specific definition for what constitutes a "cluster" of illness. A cluster is identified when there are three or more cases of the same illness within a single classroom or epidemiological cohort (a group of individuals with a shared exposure) during a 7-day period. When a cluster is identified, appropriate measures will be taken to manage the situation and prevent further spread. By following these guidelines, we aim to maintain a healthy school environment while providing clear communication and support to our families.
