A communicable disease is an illness caused by an infectious agent or its toxic product that can be transmitted in a workplace from one person to another. Examples of communicable disease that may circulate in the workplace include norovirus and seasonal influenza. 

The level of risk of certain communicable diseases may increase from time to time or on a seasonal basis. OLA administration and OLA’s Joint Health and Safety Committee will monitor and review school and community communicable disease-related information (including orders, guidance, notices and recommendations) issued by our regional or provincial medical health officer. 

Please refer to OLA’s Communicable Disease Prevention Plan for further details – revised September 2026.
