The Windsor-Essex County Health Unit says the rate of COVID-19 cases has nearly doubled in just a week.
The region is seeing about 36 cases per day, whereas this time last week it was around 20 per day.
Ramsey D'Souza, manager of epidemiology for the public health unit, presented the data during a virtual briefing Thursday morning.
"So almost a two-fold jump," he said.
Cases are rising across the province, and while the increase has been more dramatic in Windsor-Essex, other health units are seeing things escalate even more, according to D'Souza.
People 19 and under make up about 21 per cent of the cases in the last two weeks, whereas throughout the pandemic people in that age group accounted for 15 per cent.
WECHU reported 66 new cases on Thursday, the highest daily uptick seen since early September. There are 326 active cases and 20 people are in hospital.
The pandemic's death toll has risen by one, to 468.
Person under 20 dies
The person who died was under 20 years old, the youngest person to pass away after contracting COVID-19 in the region.
That death was first reported in provincial statistics on Wednesday. On Thursday, the region's acting medical officer of health, Dr. Shanker Nesathurai, declined to comment on the individual's vaccination status, saying no further information would be released due to privacy.
