Four years after the first cases of what was later called COVID-19, infections continue to spread and lead to new cases of long COVID. However, the mystery that still surrounds this persistent disease limits the ability of health professionals to intervene.

According to recent data released by the Canadian COVID-19 Health and Antibody Survey (CADTH), about one in nine Canadian adults, or 11.7% of the population, claims to have suffered long-term symptoms from SARS-CoV-2 infection.
