COVID-19 Long-term Impact

Project Background

Long-COVID, also known as “post-COVID conditions” or “post-acute COVID-19 syndrome”, amongst others, is a complex condition characterized by symptoms that persist weeks to months after acute COVID-19 illness. These symptoms may be mild to severe and involve a range of body systems, including the respiratory, circulatory, nervous, gastrointestinal and musculoskeletal systems. Small clinical studies indicate that approximately 30% to 70% of individuals diagnosed with COVID-19 may experience long-COVID, depending, in part, on disease severity. Consequently, given the large number of COVID-19 cases in Canada and worldwide, long-COVID could have a major population-level impact on health status and healthcare utilization. Comprehensive population-level analyses are therefore essential to characterize the constellation of symptoms that make up long-COVID and to identify the demographic, clinical, social and other risk factors associated with this condition. 


Leveraging data from the BCC19C, our project seeks to characterize the burden of long-COVID in British Columbia and Ontario, Canada through a health equity lens by:  

  1. Determining risk factors and population-level burden of health outcomes, resource use, and healthcare costs attributable to the long-term impacts of COVID-19 
  2. Mapping the clusters of syndromes indicative of the long-term impact of COVID-19 to determine attributable incidence, risk factors and burden of syndromes that are associated with the long-term impact of COVID-19
