Saskatchewan reported 299 new cases of COVID-19 Thursday. Three residents who tested positive for the virus have died — a person in Saskatoon in their 70s, and two in the 80 and over age group in the northwest zone. There have now been a total of 40 deaths in the province due to COVID-19. Of the cases announced Thursday, 72 are from the Saskatoon Correctional Centre, including 68 offenders and four staff.Those numbers are a sharp increase from a week ago. As of Nov. 21, only one inmate and one staff member at the facility had tested positive for COVID-19.There are now 85 known active cases among offenders and staff at Saskatoon Correctional Centre.Correctional facilitiesThe province says corrections officials are working with public health on measures to reduce the spread within the Saskatoon facility and within the correctional system. Those measures will include ongoing testing of offenders and staff at the Saskatoon Correctional Centre.All new admissions to provincial correctional centres will be tested for COVID-19 starting early next week. New admissions will continue to be quarantined for 14 days."Given that we tested a large amount of people and we had such a high number of cases come back, we are going to do a large amount of testing to get a better picture of what's happening in these facilities so that we can manage it better," said Noel Busse, executive director of communications for the Ministry of Corrections, Policing and Public Safety, during a media conference call Thursday. The province said Corrections is instituting mandatory continuous masking for offenders across all provincial correctional facilities. Employees at correctional centres have been masked up since the summer, according to the province. But masks have not been available to all offenders."Under the previous health order, it wasn't mandatory for offenders to wear masks in the common areas," which would be considered "clean units," said Busse."Everybody in those units would have been through the 14-day assessment unit. They weren't they were considered public areas."As of Thursday, there will be no new admissions to Saskatoon Correctional Centre. The province says remanded and sentenced offenders are being redirected to Regina and Prince Albert correctional centres.There are currently no active cases at Pine Grove Correctional Centre in Prince Albert. The Regina Correctional Centre has two cases among staff and one case involving an offender, and there is one active case among staff at the Prince Albert Correctional Centre.'From zero to 100 in about 4 days'The union that speaks for staff at the jail says that it wants the province to offer workers "optional accommodation" because of the high risk they now face at the facility."No one wants to carry this infection outside of the correctional centre," said Glenn Billingsley, a labour relations officer with the Saskatchewan Government and General Employees' Union (SGEU)."We want to keep it contained and manage the best we can within the facility."Billingsley said the COVID-19 numbers at the jail exploded over four days, with one inmate and three staff testing positive on Saturday."We went from zero to 100 in about four days," he said.All of the estimated 200 staff at the jail are now getting tested and Billingsley expects the number of known positive cases to climb by Friday.Numbers breakdown The seven-day average of daily new cases in Saskatchewan as of Thursday is 243 per day — 20.1 new cases per population of 100,000.
