The U.K. COVID-19 variant has been confirmed in 39 cases across York Region, according to the municipality.

Three cases were detected in Newmarket, four in Georgina and King, five in Richmond Hill, and the most infections were recorded in Vaughan, with 12, and Markham with 11.

While the majority are now resolved, the municipality said there are 24 households associated with the cases, and 10 were spread through "local transmission."

"This further reinforces the need for everyone to stay home, limit trips outside of your home for essential reasons only and continue following all public health advice," stated a spokesperson for the Municipality of York.

While the variant remains a serious concern, the municipality says it's not aware of any long-term care home in York Region with cases of the U.K. strain, also known as the B.1.1.7 variant.

As of Monday, the new strain had also not been linked to any deaths in York.
