"Our results highlight the strength of Alberta's pandemic preparedness and our response in the early days of the pandemic", said Hinshaw.
Angela School and Lester B. Pearson High School in Calgary, as well as Raymond High School in Raymond and Lawrence Grassi Middle School in Canmore, have all reported in letters to parents that a case of COVID-19 has been diagnosed.
"We get parents to send us a screenshot of correspondence from principals, school districts or directly from Alberta Health Services", Wing Li, communications director for the advocacy group, said Tuesday.
The resource for parents of K-12 students will be regularly updated, and its aim is to provide families with complete transparency of COVID-19 outbreaks.
According to AHS, there are three brackets that schools will fall under if COVID-19 cases are confirmed at the facility.
None of the schools have declared outbreaks and all remain open.
AHS has already defined close contacts of the two cases within the school context, and those individuals have been contacted by the school through an emailed letter and individually by AHS.
Opposition NDP education critic Sarah Hoffman says there are at least 20 COVID-19 cases in schools, with 16 of those infections reported since Friday.
She said she's concerned with the rise in case numbers across the province.
But overall, with the majority of Alberta's 750,000 students and 90,000 staff back in school, the infection rate in the school community is low, Hinshaw said.
Masks are mandatory in schools for students in grades 4 to 12 when there can not be physical distancing. Edmonton is under Alberta Health's watch with a 53.1-active case rate per 100,000 people.
Similarly, Dr. Deena Hinshaw, the province's chief medical officer of health, said there was no flawless way for the province to relaunch - and no matter the levels of protection implemented, some cases will occur.
