Communicable disease is defined by Memorial University as an infectious disease that is spread from person to person through casual contact or respiratory droplet to include, but is not restricted to the following:

• Influenza
• Chickenpox
• Norovirus
• Measles
• Meningitis
• Tuberculosis
• Mononucleosis
• West Nile Virus 

 A communicable disease may be transmitted directly from one body to another without the aid of other objects, e.g. kissing, droplet spray from sneezing, coughing, spitting, singing or talking. It may be transmitted directly when an object transmits the organism. Objects of transmission may be clothing, linen, utensils, food, water, milk, air, soil, or insects.

The University endorses a 3 C Campaign (Clean, Cover and Contain) to help prevent the spread of communicable diseases.
