Annual data from the Public Health Agency of Canada shows a record number of bacterial infections that have been deadly in rare cases, especially among children.
The agency says that as of last week, its lab detected an invasive Group A streptococcal infection in more than 4,600 samples that provinces sent last year to its lab.
It says that is the highest annual number of invasive Group A strep samples submitted, with the previous peak of 3,236 samples in 2019, before the pandemic.
