Description Between July and August 2020, CCM replaced the integrated Public Health Information System (iPHIS) for COVID-19 for most health units in the province. COVID-19 cases in iPHIS were migrated over to CCM with key reporting elements. iPHIS is used for collecting information on all other reportable diseases in Ontario. The numbers of cases of COVID-19 in CCM is an underestimate of the actual numbers since not all people with COVID-19 develop symptoms, seek medical treatment or testing, and therefore, the disease goes unreported.
Purpose The Case and Contact Management System (CCM) is a central data repository for COVID-19 case and contact management, and reporting in Ontario. This information is used for local, provincial and national surveillance.
Scope The Health Protection and Promotion Act requires that each public health unit in Ontario collect information about people with diseases of public health significance (reportable diseases), including COVID-19, in their jurisdiction and report it to the Ministry of Health (MOH).
