Communicable Disease Prevention/Control
Communicable diseases, sometimes called infectious diseases, are illnesses caused by organisms such as bacteria, viruses, fungi and parasites. Sometimes the illness is not due to the organism itself, but rather a toxin that the organism produces after it has been introduced into a human host.

Communicable diseases may be transmitted (spread) in the following ways:

  • By one infected person to another
  • From an animal to a human
  • From some inanimate object (doorknobs, table tops, etc.) to an individual

Some communicable diseases can be spread in more than one way.

Follow-up, education, surveillance, and investigation are completed by the Clark County Health Department for all reportable communicable diseases.
