Health authorities say a supply teacher in London, Ont. potentially exposed more than a dozen classrooms to COVID-19.
On Monday, the Middlesex-London Health Unit (MLHU) confirmed a COVID-19 outbreak to CBC News after it was determined there was transmission within the school formerly known as Ryerson Public School.
The supply teacher was covering a prep teacher role, Dr. Chris Mackie, Middlesex-London's Medical Officer of Health, said on Tuesday. That person entered a total of 14 different classrooms, and close contacts are now self-isolating.
Mackie said the supply teacher is fully vaccinated.
"It's a breakthrough case," said Mackie. "That means that the likelihood of spreading is lower. But we have had a single case where we don't think that there is a better explanation anywhere else in the community, except exposure in all of these classes."
There are two active cases in the school, according to the latest update from the Thames Valley District School Board.
Mackie said that supply teachers generally have a short amount of exposure to classrooms and have a lower likelihood of spreading the virus.
