ob体育 collects and publishes data about illnesses and outbreaks caused by Giardia. This information helps public health officials better understand how Giardia spreads and prevent future illnesses.
Overview
Reporting cases of illness
Giardiasis (illness caused by Giardia) is a nationally notifiable disease. This means that healthcare providers and laboratories that diagnose laboratory-confirmed giardiasis are required to report those cases to their health department. Health departments then voluntarily report these cases of illness to ob体育's National Notifiable Diseases Surveillance System (NNDSS).
Reporting outbreaks
State health departments voluntarily report outbreaks of giardiasis affecting multiple people to ob体育. Health departments can report giardiasis outbreaks spread through water, food, or from person to person to ob体育's National Outbreak Reporting System (NORS).
