Overall

The age-standardized emergency visit rate for asthma in Simcoe Muskoka for all ages and sexes in 2020 was 186 (174.6, 197.2) visits per 100,000 population, which was significantly higher than the Ontario rate of 151 (149.1, 153.2) visits per 100,000 population.

The asthma emergency visit rates dropped dramatically in 2020, by more than 40%, in both Simcoe Muskoka and Ontario as a whole. This sudden and dramatic drop can be attributed, at least in part, to changes in health care use and access during the COVID-19 pandemic. It is unclear how much the reduced transmission of other infectious diseases (like the common cold and influenza) and reduced exposures to activities and environments that exacerbate asthma may have contributed to the drop in the rate.

Prior to 2020, there was a significant downward trend in the asthma emergency visits rates, both in Simcoe Muskoka and Ontario as a whole, over the 15-year time period from 2005 to 2019. The steepest decline in the rates occurred between 2005 and 2010, which was followed by a more moderate decrease from 2010 to 2019.
