Trends Over Time

Due to the increase in cases being reported to public health, less information is being collected about demographics, geography, and acquisition, and as such new cases may not contain complete information. Charts below describing case acquisition (e.g. close contact of a case or community-acquired) are impacted by this change in case management.

Summary

  • Young adults 18-34 have had the highest infection rate since Omicron has become the dominant strain.
  • While the rate of new infections among females was higher than males in January, this difference was mainly due to a higher number of female cases associated with institutional outbreaks. But from July 2021 to November 2021, infection rates were fairly similar for males and females. However, starting with the onset of Omicron in December, females have once again had higher infection rates than males. This is due, in part, to a higher number of female cases associated with outbreaks.
  • The effective reproduction number for a given period of time or Rt is the average number of secondary cases that a new case will infect. If Rt is greater than one it indicates that the spread of COVID-19 in Simcoe Muskoka is growing, and if Rt is less than one, the spread of COVID-19 is slowing and containment/mitigation efforts may be working to keep the outbreak under control. Currently, Rt cannot be estimated accurately because the testing capacity in Ontario is insufficient to deal with the number of infections caused by Omicron, and the testing strategy has changed.
