Quebec expands COVID-19 rapid testing in primary schools Dr. Melissa Généreux, a public health official from the Estrie region, said the cases were observed in 13 different classes and included a teacher and students from kindergarten to sixth grade.Genereux said the cases can be linked to students spending more time in common areas this year, such as the cafeteria and an absence of classroom bubbles.“We’ve got a mix that facilitated the spread,” she said.Education Minister Jean-François Roberge announced as the school year began that students would not be restricted to classroom bubbles and those in high school would be able to attend school full-time.
