From the onset of the pandemic in March 2020, YorkRegion.com set out to track every case in York Region, mapping COVID-19 hotspots and cases in the community.Â
As the situation changes, those numbers now come with a warning.Â
With the rapid rise of the highly transmissible Omicron variant and the province shifting its COVID-19 testing to high-risk or symptomatic people, the region is changing its interactive COVID-19 dashboard.Â
"Many health units are now faced with the reality case data reported externally is not a true representation of emerging cases," Patrick Casey, York Region director of corporate communications, said.Â
In fact, the case counts posted daily by York Region Public Health "are an underestimate of the true number of individuals with COVID-19 in York Region".
Case counts should be interpreted with caution.Â
"Daily case counts will only reflect a particular piece of the overall picture of COVID-19 transmission," Casey said. "The numbers will be an undercount of the true burden of illness in the community and will not accurately reflect transmission rates and community risk."
The actual number of cases is expected to be much higher as Omicron continues to spread, he added.Â
While YorkRegion.com will continue to monitor the number of positive COVID-19 cases as reported by public health, the focus will shift to our hospitals and the strain on resources posed by COVID-19.Â
Here, you will find the number of COVID-19 cases in each of York Region’s four hospitals as well as how many COVID-19 patients are in an intensive care unit (ICU).
