Communicable diseases are illnesses caused by infectious agents like bacteria, viruses, parasites, or fungi that can be spread from one person to another, either directly or indirectly. This means that if someone with a communicable disease sneezes, coughs, or even touches something, they can pass the disease on to someone else.

Therefore, it is essential to prevent the spread of Communicable diseases, such as washing your hands, covering your mouth and nose when sneezing or coughing, and avoiding contact with sick people.
