A disease is an unhealthy condition of the body or mind. A communicable disease, such as a cold, is a disease that spreads from person to person. A noncommunicable disease, such as cancer, is a disease that does not spread from person to person - you can't catch it from someone else.
Health Department nurses watch for communicable diseases in our community. When one is reported, nurses follow up to help prevent the disease from being spread to other people.
Anyone can report communicable diseases, but hospitals, doctors and laboratories are required to notify the Health Department about specific reportable communicable diseases.
