Lindsay Thurber High School up to nine COVID-19 cases

Lindsay Thurber Comprehensive High School is dealing with an outbreak of COVID-19.

In a letter to students and parents Thursday, principal Chris Good said the school was made aware of five more cases.

In the past week, the school has been notified a total of nine students have been infected.

In the letter, Good says they have not received any information about transmission within the school by Alberta Health Services.

“Our investigation leads us to believe that most of these cases have been brought into our school from the community,” Good said in the letter.

The principal said Alberta Health Services will investigate the origins of the cases and make recommendations as necessary.

According to AHS, an outbreak is declared at a school when there are two or more confirmed cases in a 14-day period.

An outbreak isn’t declared over until there have been no new COVID-19 cases in a school for 28 days.

Central Middle School also had a new case confirmed Thursday, and last had a reported case on Oct. 19.

Holy Family School in Red Deer is also investigating a case of the virus.

Last month, Hunting Hills High School declared an outbreak, after three cases were reported within the 14-day period.
