We have seen shifts over time in the age groups being most severely impacted by COVID-19 that align with shifts in exposures in the community. At the beginning of the pandemic we saw increased rates of infection among older populations, notably people in their 70s and 80s, especially as long-term care facilities reported outbreaks. As COVID-19 began spreading further in the community, we began to see increased rates among people aged 20-40 years, which includes a large portion of our essential workforce. We continue to monitor trends in age demographics to better understand community spread.
