Notifiable Diseases On-Line
National Notifiable Diseases
Communicable diseases (CDs) are made notifiable in the provinces and territories of Canada by provincial and territorial statute. The list of notifiable diseases at the federal level is agreed upon by consensus among provincial, territorial and federal health authorities, using agreed upon criteria. The Final Report and Recommendations from the National Notifiable Disease Working Group outlines the rationale behind the choice of diseases, and the process to choose the list that is current in 2009. In this review, the changing epidemiology of infectious diseases results in some previously notifiable diseases being removed from the list and new communicable diseases added. The reader should refer to Table 1 to determine the years in which a specific communicable disease has been reportable, and for links that provide details about each disease. The purpose of making a specific CD reportable is to facilitate both tracking and required control efforts by public health personnel. In addition, the NND list helps to promote uniformity and synergy among the provincial and territorial efforts and conformity with international reporting requirements.
Notifiable Diseases On-Line is a web based application developed by the Notifiable Diseases Section of the Public Health Agency of Canada to enhance dissemination of surveillance data collected on notifiable diseases in Canada.
The application contains information on the number of cases reported for several of the notifiable diseases as well as their rate in the population. The data are available for each province and territory for each year starting at 1989 and is updated when data can be finalized with the provinces and territories. (For 1999, Northwest Territories and Nunavut data have been combined). Please see the Technical Notes section for more information on reliability of measures over time.
Please note:
- The rates are based on reporting provinces and territories only.
- Data are subject to change due to updates from provinces and territories. Changes are rarely great enough to significantly alter the rates presented.
- Changes in case definitions, including confirmatory tests, may have any effect on rates over time. Please see the Technical Notes section for possible effects on disease trends of the 2009 Case Definitions.
How to Use Notifiable Diseases On-Line
This section provides information on the use of notifiable diseases data, limitations of the data, and important considerations to be taken into account when analyzing and interpreting the data.
Notifiable Disease Maps
This section will allow the user to create maps of Canada showing the number of reported cases and rates of infection per 100,000 population for selected notifiable diseases. The data may be broken down by sex, age-group and year.
Notifiable Disease Incidence
by Year, 1989-2001
This section will allow the user to generate tables and charts which
display the number of reported cases and the rate of infection per 100,000
population for a selected notifiable disease over the time interval from
1989 to 2001. The number of cases and rates of infection may be broken
down by gender, age-group, and province/territory.
Notifiable Disease Incidence
by Province/Territory
This section will allow the user to generate tables and graphs which
display the number of reported cases and rate of infection per 100,000
population for a selected notifiable disease by province/territory. The
data may be broken down by gender, age-group, and year. The user may
select double bar charts to compare the data by two or more of the variables
at the same time.
Incidence by Notifiable Disease
This section will allow the user to generate tables and charts which
display the number of reported cases and rate of infection per 100,000
population by one or more notifiable disease. The data may be broken
down by gender, age-group, province/territory, and year.
Notifiable Disease Incidence by Age Group
This section will allow the user to generate tables and charts which
display the number of reported cases and the rate of infection per 100,000
population for a selected notifiable disease by age-group. The data may
be broken down by gender, province/territory and year.
Line Charts will display trends over age groups.
Pie Charts will outline incidence with age groups.
Horizontal Bar Charts compare the rates for all age groups.
