The number of people in intensive care rose to 262, an increase of 24%.

Additionally, Canada’s chief public health official notes that the delta variant is responsible for the majority of new infections. She is also concerned that this alternative could interfere with the effectiveness of vaccines.

Public health is also concerned with the emergence of new variables in regions and environments where the vaccination rate is lower. This situation may also contribute to the spread of vaccine-resistant variants.
