Information for Public Health & Medical Professionals
Surveillance and Outbreaks
Giardiasis is a nationally notifiable disease. This means that health care providers and laboratories that diagnose cases of laboratory-confirmed giardiasis are required to report those cases to their local or state health departments, which in turn report the cases to CDC.
For more information, see Nationally Notifiable Diseases.
Outbreaks of giardiasis affecting multiple people that are related to water, food, or person-to-person transmission should be reported to CDC by state health departments. It is important to inform local, state, and federal health authorities about cases of giardiasis so that appropriate public health responses can be taken to help control the spread of this disease.
