Infectious Disease Trends in Renfrew County and District Dashboard

The Ontario Health Protection and Promotion Act lists approximately 70 infectious diseases that must be reported to local health units. These are referred to as Diseases of Public Health Significance (DOPHS). This dashboard provides case counts and rates for all DOPHS reported to Renfrew County and District Health Unit (RCDHU) over the past 10 years (2014-2023). Annual rate comparisons with Ontario overall are also included. In this dashboard, DOPHS are classified into the following disease categories:

  • Enteric Disease and Food-Borne Disease
  • Respiratory Disease
  • Sexually Transmitted Infections (STIs) and Blood-Borne Infections (BBIs)
  • Vaccine Preventable Disease
  • Vectorborne Disease
  • Zoonotic Disease
  • Other Disease

This dashboard was created for local health care providers, community partners, and the public to enhance understanding of local infectious disease trends and to support evidence-informed decision making related to infectious disease.

Data source: Integrated Public Health Information System (iPHIS) and the Public Health Case and Contact Management Solution (CCM) accessed through Infectious Diseases Query, Public Health Ontario (PHO). Updated March 13, 2024. Data extracted by Renfrew County and District Health Unit March 18, 2024.

iPHIS and CCM are dynamic reporting systems which allow ongoing updates to data previously entered. As a result, data extracted from these data sources represent a snap shot at the time of extraction and may differ from previous or subsequent reports.

Case counts presented in this tool include only the confirmed classification for all diseases, except for the following diseases where both confirmed and probable cases are included in the total counts: amebiasis, Lyme disease, mumps, pertussis, invasive meningococcal disease, invasive Haemophilus influenzae disease, and West Nile virus illness.

Case classifications and disease-specific information are specified in the provincial surveillance case definitions outlined in Appendix 1 of the Infectious Diseases Protocol:

Complete 10-year historic data is not available for the following diseases because the disease became reportable at some point between 2014-2023: Blastomycosis (2018), Carbapenamase-producing Enterobacteriaceae (CPE) (May 2018), Echinococcus multilocularis infection (May 2018), COVID-19 (January 2020), Mpox (July 2022), Anaplasmosis (May 2023), Babesiosis (May 2023), Powassan Virus (May 2023).

Cases are reported based on ‘episode date’, with the exception of CPE, HIV, AIDS and Tuberculosis (TB). The episode date is an estimate of the onset date of disease for a case.

A case is reported as encephalitis and/or meningitis when an agent is not specifically identified through laboratory testing or is not reportable.

Due to the impact of the COVID-19 pandemic on the public health and health care sectors, there may be limitations with the 2020, 2021 and 2022 data presented in this tool. Trends should be interpreted with caution.
