Case and Contact Management System (CCM)
The Case and Contact Management System (CCM) is a central data repository for COVID-19 case and contact management, outbreaks and all adverse events following immunizations, and reporting in Ontario. The Health Protection and Promotion Act requires that each public health unit in Ontario collect information about any case of a disease of public health significance (reportable diseases), including COVID-19, in their jurisdiction and report it to the Ministry of Health (MOH). This information is used for local, provincial and national surveillance.
Ontario Ministry of Health
- 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 and outbreaks in iPHIS were migrated over to CCM with key reporting elements. Adverse events following immunizations were also migrated over to CCM between 2021 and 2022. 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.
