About us

Infectious diseases are caused by microorganisms, such as bacteria, viruses or parasites, that can cause disease. Not all infectious diseases have a cure, but most are treatable or preventable.

Different types of infectious disease can spread in different ways:

  • Contact with a person who has an infection
  • Bites from insects or animals that carry an infectious organism
  • Ingestion of contaminated food or water
  • Environmental exposure to an infectious organism
