Diseases to report

The health-care system identifies most cases of reportable disease. A provider who knows or suspects that a child or worker suffers from a reportable disease should contact their Licensing Officer, Public Health Nurse or Environmental Health Officer.

Remember that information about someone’s health is private information and should be treated with confidentiality.

Notifying Public Health of an outbreak of diarrheal disease

Some diseases that are not “reportable diseases” can still cause serious illness and need to be followed up by public health to determine the cause and to prevent spread. Many of these diseases cause diarrhea and vomiting

Providers in child care centres should notify public health, when 3 or more children have been sick with similar symptoms, such as diarrhea or vomiting, within a short period of time.
