Communicable Diseases

A communicable disease such as a cold is a disease that spreads from person to person. When a person becomes sick with a communicable disease it means a germ has invaded their body. The spread often happens via airborne viruses or bacteria, but also through blood or other bodily fluid. Germs are tiny organisms (living things) that may cause disease. They are so small and sneaky that they creep into our body without being noticed.
